Plant Quarantine
The term ‘Quarantine’ is derived from the Latin word quarantum, meaning 40. It refers to the 40 days period of detention of ships from countries with bubonic plague and cholera in the Middle Ages. The first such quarantine was imposed in Venice in 1374.Present quarantine laws now include plants. Plant quarantine , restrict entry of plants, plant products, soil, cultures of living organisms, packing materials, and commodities, as well as their containers and means of conveyance to protect agriculture and the environment from avoidable damage by hazardous organisms.They exclude dangerous organisms while permitting plants and plant products to enter. The term exclusion convey this objective more clearly than plant quarantine. Exclusion relates to keeping organisms out; plant quarantine relates to keeping plants out.
In strict sense ‘Plant Quarantine’ refers to the holding of plants in isolation until they are believed to be healthy. Now, broader meaning of the plant quarantine covers all aspects of the regulation of the movement of living plants, living plant parts/plant products between politically defined territories or ecologically distinct parts of them. Intermediate quarantine and post entry quarantine are used respectively to denote the detention of plants in isolationfor inspection during or after arrival at their final destination.

The overuse of chemical pesticides and farmers’ improper application of them have resulted in a number of issues, including residue in food, feed, and fodder; resistance developing; resurgence, secondary outbreaks; and, most importantly, pollution of the environment. This has caused a condition known as Pesticide Treadmill, which is characterized by the need to apply ever-increasing amounts of chemical pesticides. Integrated Pest/Management was developed as an environmentally sound substitute for the exclusive use of chemicals after Rachel Carson’s book “Silent Spring” in 1962 sparked widespread concern about the overuse of pesticides.
The IDM Concept
In disease management, every alternative control strategy—cultural, biological, mechanical, resistant varieties, physical, etc.—is applied in combination to keep the disease below the threshold of economic injury . In order to control the disease, pesticides are employed if it spreads and hits the economic threshold. With consideration for the agro-ecosystem, this approach to integrated disease management uses the minimum amount of pesticides possible. In reality, we don’t aim for complete control while managing diseases—rather, we let them progress below what is tolerable, such as the economic threshold. Additionally, it offers agents the chance to endure by controlling the diseases and maintaining a particular state of equilibrium. Therefore, the goal of the integrated disease management concept is to manage the disease using all available strategies while achieving positive effects on the environment, society, and economy.

Cold storage is a widely used method for handling perishable goods in bulk between production and marketing stages. It is essential for preserving the freshness and quality of perishable commodities by controlling temperature and humidity within the storage environment. Ensuring the temperature remains sufficiently low is crucial, as failing to do so can lead to chilling damage to the produce. Additionally, maintaining a relative humidity of 85-90 percent in the storage area is vital for most perishables, as lower humidity can negatively affect their quality.
Fruits and vegetables, if stored at ambient harvest temperatures, have a very short shelf life. Post-harvest cooling helps to quickly remove field heat, thus extending the storage duration. Proper cooling after harvest can:
• Reduce respiration and enzymatic degradation;
• Minimize water loss and prevent wilting;
• Slow or stop the growth of microorganisms that cause decay;
• Lower the production of ethylene, the natural ripening agent.

Abstract
India holds a dominant position in the global production and export of castor, accounting for nearly 88% of global and leading the international the international castor oil trade. This chapter investigates the status of castor production and trade dynamics, highlighting India’s evolving role in commercial agriculture and export-oriented strategies. Castor, a non-edible oilseed with significant industrial applications, is primarily cultivated in Gujarat, Rajasthan, and Andhra Pradesh. The study explores trends in area, production and yield across states and districts, alongside export trends over a 15 year period (2006-06 to 2019- 20). Results show positive growth in export quantity, value and unit price, despite fluctuations, supported by favourable policies and quality improvements. Using the Markov chain model, the direction of trade analysis reveals China as the most stable and dominant importer, followed by Netherlands and France. The USA also shows emerging potential. Instability indices indicate relatively low volatility in trade metrics. The finding suggest that while India maintains a strong global presence, strategic efforts are needed to sustain existing markets and explore new opportunities, especially in emerging economies offering better prices and reliability.

ABSTRACT
India’s agricultural exports play a pivotal role in driving economic growth, enhancing rural livelihoods, and generating employment. The Agricultural and Processed Food Products Export Development (APEDA), establishedunder the Ministry of Commerce and Industry, has significantly contributed to the augmentation of India’s agri-exports through strategic interventions. This chapter explores APEDA’s multifaceted initiatives, including quality control, infrastructure development, product diversification, and digital innovations such as paperless systesm, mobile apps, and virtual trade fairs. Notable efforts include the promotion of Geographical Indication (GI) products, expansion of Agri-Export Zones (AEZs), and international marketing of millets during the International Year of Millets (IYOM 2023). APEDA’s Market Access Initiative (MAI) and Agri- Exchange portal have facilitated global trade linkages, while collaborations with institutions and FPOs have strengthened grassroots connections. Recent achievements include surpassing USD 19.69 billion in agri-export value in 2022- 23 and expanding to over 200 countries. This comprehensive engagement reflects APEDA’s central role in branding Indian agriculture on the global stage and positioning India as a reliable exporter of high-quality food products.

English name : Black pepper
Botanical name : Piper nigrum L.
Family : Piperaceae
Chromosome number : 2n = 52
Centre of origin : Western Ghats, India
Black of the commerce is the dried mature fruit of the perennial climbing vine of Piper nigrum L. It is one of the oldest and most significant spices in the world. Black pepper refers to the whole dried fruit, which is still unripe, while white pepper is made from the fruit after the mesocarp has been removed. Among all spice crops, pepper holds the highest share in foreign exchange, earning it the title of the “King of Spices.” An analysis of various types of black pepper from Kerala, Karnataka, Tamil Nadu and Assam revealed the following ranges of values: moisture content (8.7-14.1%), total nitrogen (1.55-2.60%), nitrogen in non-volatile ether extract (2.70-4.22%), volatile ether extract (3.0-4.2%), non-volatile ether extract (3.9-11.5%), alcohol extract (4.4-12.0%), starch (28-49%), crude fibre (8.7- 18.0%), crude piperine (2.8-9%), piperine (spectrophotometrically) (1.7- 7.4%), total ash (3.9-5.7%), and acid-insoluble ash (0.03-0.55%). Starch is the principal constituent of pepper, making up 34.8% of black pepper, 56.5% of white pepper, and 63.2% of decorticated white pepper. Pepper starch consists of small, polygonal granules similar to rice but much smaller. The alkaloid piperine (melting point: 29-30°C) is the primary compound responsible for black pepper’s characteristic biting taste. Other pungent alkaloids present in smaller quantities include chavicine, piperidine, and piperetine.

Abstract
All the technologies are applied from harvesting of fruits to its final consumption is called as post harvest technology. Development of processing industry takes care of surplus produce as well as of those fruits that are of lower quality. With the development of processing industry citrus fruits can be utilized for the production of wide range of commercial products. The large variability in physico-chemical characteristics of citrus fruits provides an opportunity to select desirable types for commercial exploitation. In India citrus fruit is available in large quantity that can be processed in to different processed products very easily. The fresh citrus fruits are not consumed in large quantity as fresh fruit due to high acidic in taste. The post-harvest technology including value addition would provide opportunity for commercial exploitation of the citrus fruits and leads to the marketing and processing in to quality products.

Introduction
Agriculture plays a vital role in global food security and economic development. However, in many regions, agricultural productivity is hindered by various challenges, including the presence of high soil salinity in agroecological systems (Singh, 2009). Saline agroecological systems are found in various regions worldwide, including coastal areas, arid and semi-arid regions, and areas affected by improper irrigation practices. These systems are characterized by high soil salinity levels, which can have detrimental effects on crop growth, nutrient availability and plant water uptake (Rai et al., 2020). Addressing these challenges requires specialized knowledge and tailored strategies to ensure sustainable agricultural practices in such environments (Dagar et al., 2019;
Sethi et al., 2016). Farm advisory and resource management services play a critical role in assisting farmers in saline agroecological systems by providing expert guidance, information dissemination, capacity building, and policy support (Adak et al., 2020). Farm advisory can play a crucial role in helping farmers understand the intricacies of saline agroecological systems, including the causes of soil salinity, its effects on crop performance, and the necessary strategies for managing these challenges effectively. Farm advisory can assist farmers in selecting suitable crop varieties that exhibit tolerance to high salinity levels. This requires comprehensive knowledge of salt-tolerant crops and and nutritional needs. Providing information on the performance and market
demand of different crop varieties enables farmers to make informed decisions about crop selection, optimizing productivity in saline agroecological systems (Kumar et al., 2020; Singh et al., 2021). It can offer guidance on crop management practices tailored to saline environments by providing recommendations on irrigation scheduling, water management techniques, and appropriate fertilization strategies to minimize salt accumulation and maximize crop yields. Helping farmers implement best practices for s

Introduction
Horticulture is distinct from other economic sectors as its output is heavily reliant on weather conditions. The degree of success of horticultural production and economics is decided to a large extent by how well weather conditions corresponding to the crop’s optimal requirements are best utilized to raise the crops. Also, how successfully adverse weather circumstances, such as moisture, thermal, wind, radiation and biotic stresses were handled to minimize adversity. It is well understood that variability in weather elements (particularly rainfall and temperature) is the primary cause of inter-annual variability in crop output. The onset of weather extremes (dry spells, droughts, floods, heat waves, and hailstorms) has a negative impact on horticultural yield, resulting in a low level of productivity. Furthermore, weather can have an impact on output at multiple levels (vegetative stage, harvest, transportation, storage, etc.). Flooding, droughts, heat waves, cold spells, hailstorms, and other natural calamities pose significant risks to farms. These natural catastrophes can lead to lower yields, leaving uninsured farmers with little income for the season. Farmers often plant low-risk, low-return crops (such as early maturing varieties that are drought-resistant) to deal with erratic weather rather than investing in more profitable crops that are more sensitive to weather fluctuations and extremes. Thus, atmospheric stress has significant impacts on the food ecosystem (Bal and Minhas, 2017; MANAGE, 2018).

Taxonomy, also known as systematics, is the study of classifying organisms into logically related groups. Historically, taxonomy was performed by examining physical characteristics of organisms and classifying species based on the most commonly held traits. Unfortunately, this method of classifying plants and animals assumes that because they share physical characteristics, they must have shared ancestors. Markers are used over the years for classification of plants. Markers are any trait(s) of an organism that can be identified with confidence and relative ease, and can be followed in a mapping population. They can be defined as heritable entities associated with the economically important trait under the control of polygenes. Molecular markers are any kind of molecule indicating existence of a chemical or a physical process. Molecular markers include biochemical constituents (e.g. secondary metabolites in plants) and macromolecules (e.g. proteins and deoxyribo-nucleic acid). These macromolecules show easily detectable differences among different strains of a species or among different species.
The prerequisite for the improvement of any plant species are germplasm collection and its characterization to find out the diversity among the accessions. Characterization can be done by several ways which include morphological, enzymatic and genetical methods. The best way to assess the diversity is based on DNA markers which allow differentiation among genotypes without any environmental influences. These markers have a great potential to identify genetic diversity within and among accessions which help in successful implementation of pre-breeding approaches. Molecular
markers are considered the best tools for determining genetic relationships diversity as they are unlimited in number, show high polymorphism, provides more reliable information, detect more variation than morphological and biochemical markers; and are stage independent, not affected by environment and simply inherited. Molecular markers are ‘tags’ that can be used to identify specific genes and locate them in relation to other genes. They help in ensuing a desired beneficial trait to be maintained or an undesirable trait to be eliminated.

The potential of Vegetable Genetic Resources (VGR) is vast, offering solutions to future challenges such as food and nutritional security. Achieving this requires the identification, collection, conservation, documentation, and utilization of these resources. The introduction and acceptance of improved varieties have resulted in the replacement of numerous landraces and local crop cultivars across various agri-horticultural crops, with a particular impact on vegetables. The alignment of activities related to the management of plant genetic resources at both global and national levels has enhanced the opportunities for utilizing VGR. India possesses a rich diversity of vegetable genetic resources, comprising indigenous and exotic varieties. Information regarding VGR in the Indian region can be accessed through passport data, conservation records, catalogs detailing characterization and evaluation, as well as insights into local vegetable usage, all of which contribute to strengthening these initiatives. This chapter delves into vegetable genetic resources, focusing on economically significant vegetable crops of India, along with regionally important crops, potential species, and their wild relatives, highlighting efforts undertaken at ICAR, NBPGR for its collection conservation, characterization and utilization.

Globally, India ranked second in vegetable production and contributed 15.8 and 14% to global vegetable area and production, respectively. The production of vegetables in India is estimated to be 212.91 million tonnes in the year 2022-23 compared to 209.14 million tonnes in the year 2021-22. India ranked first in production of okra in the world (73% of world production) and second in brinjal (27.55%), cabbage (13%) and tomato (11%). The major vegetable growing states in India are West Bengal (14.1%), Uttar Pradesh (11.4%), Bihar (9.3%), Madhya Pradesh (8.0%) and Gujarat (7.1%). Vegetables are especially important crops for farmers with small holdings because an appreciably higher income per hectare can be generated by growing vegetables than from conventional staple crops (Genova et al, 2006). However, vegetables are generally considered more vulnerable than staple crops to stressful environmental conditions including extremes of temperatures, drought, salinity, alkalinity, water logging, mineral nutrient excesses and deficiency (Chinnusamy et al, 2005). These environmental stresses are likely to be exacerbated by the prevalent climatic changes in many parts of the world.
Among environmental factors, soil salinity stress is one of the main factor reducing production and productivity of vegetables in arid and semi-arid regions where irrigation water has excessive salt and annual rainfall is low. In India, about 6.73 million ha of land (~2.1% area of the country) is salt affected, out of which 2.96 million ha is saline and 3.77 million ha is sodic (Arora & Sharma 2017). About 75% of salt-affected areas exist in four states, i.e., Gujarat, Maharashtra, West Bengal, and Rajasthan (Mandal et al., 2018).

Vegetable crops belonging to the family Cucurbitaceae are known as cucurbits. These include 950 species in over 90 genera, mainly distributed in the tropics and subtropics (Schaefer and Renner, 2011). Enormous diversity of cucurbit genetic resources has evolved in past centuries to cater the nutritional requirements of people in different geographical and climatic regions. A large number of cucurbitaceous vegetables coming from different centres of origin are cultivated worldwide (Table 1). However, these crops are challenged by several biotic and abiotic stresses. Cultivated varieties are constrained by market demands, the necessity for climatic adaptations, domestication bottlenecks, and in most cases, limited capacity for interspecific hybridization, creating narrow genetic bases for crop improvement. Genetic resources are the building block for any crop improvement programme and includes landraces, traditional varieties, wild, weedy and other related species constituting primary, secondary and tertiary gene pools. They are valuable sources of important genetic traits needed for developing resilient and climate smart crop varieties and therefore, important for food security. The success and pace of the development depends on the efficient use of plant genetic resources. Wild relatives are incredible genetic resources carrying several desirable attributes like nutritional quality, resistance to biotic and abiotic stresses etc. Most of the crop wild relatives of cultivated crops across the world are not receiving adequate attention for their effective utilization in breeding programs. It is therefore, of utmost priority to protect them in the wild, through in-situ conservation, where they can continue to evolve and develop these useful adaptations. ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR) is the nodal agency for the management of national wealth of vegetable genetic resources speciallyworking for collections, characterization, identification and documentation of new germplasm. Besides, it also bears the responsibility for conservation of the germplasm for future through sustainable use. The Vegetable germplasm is being conserved both under in-situ and ex-situ genebanks. This chapter highlights the status of Cucurbit genetic resources and procedures to access the germplasm by various stakeholders for research use.
 

Introduction
Food Pipe Line refers to a post-harvest system that deals with ensuring the delivery of a crop/commodity from the time and place of harvest to the time and place of consumption, with minimum loss, maximum efficiency, and maximum returns to all concerned including the grower, processors, and consumer. The term ‘system’ represents a dynamic, complex aggregate of logically interconnected functions or operations within a particular sphere of activity. The term pipeline refers to the functional succession of various operations but tends to ignore their complex interactions.
Stages of the post-harvest system
The food commodities broadly undergo different stages/operations of postharvest systems right from harvest to consumption. However, the applicability of different stages varies with the type of crop. Different unit operations involved in the post-harvest system of food commodities are as under:
1. Harvesting
2. Threshing (food grains, pulses and oilseeds)
3. Drying (food grains, pulses and oilseeds)
4. Collection, Sorting, grading, packaging (Horticultural Crops)
5. Transportation and distribution
6. Storage (Godowns, cold stores, CA stores)
7. Processing

A. Tomato and Tomato Products
Tomato though botanically a fruit is generally considered a vegetable because of how it is consumed. Commercial products from tomatoes include juice, puree, paste, ketchup, soup canned and dehydrated tomatoes. Processing of tomato is now practised from home scale level to large scale enterprise. As a semi-finished product, tomato puree is prepared on a small scale while at a large scale, tomato paste has gained commercial significance. Both puree and paste are used for the preparation of different finished products like ketchup, juice, soup etc. The method for preparation of these products is well standardized, however, some modifications concerning recipes are made in the processing plants owing to variations in the quality of the raw material. The methods for the preparation of different tomato products are discussed as under: -
I. Tomato Juice/Pulp
Tomato juice is an unconcentrated product consisting of a liquid with a substantial portion of the pulp, expressed from ripe tomatoes with or without the application of heat and the addition of salt. Tomato pulp/juice is the basic ingredient for the preparation of different tomato-based products such as tomato puree, paste, ketchup etc. Fully ripe tomatoes are used for the preparation of tomato juice/pulp. All green, blemished and overripe fruits should be rejected as they adversely affect the quality of the product. The juice obtained from overripe tomatoes is usually thin and unpleasant. The juice should be deep red in colour with a characteristic taste and flavour. The juice shall have about 0.4% acidity expressed as citric acid. Cane sugar (1%) is added to further improve the taste and flavour of the finished product.

Introduction
The food that has been damaged or has undergone changes so as to render it undesirable/unacceptable/unfit for human consumption is termed as spoiled. Spoilage of processed products is mainly caused by the action of micro-organisms and due to the physical or chemical changes. The reasons for microbial spoilage include under processing, inadequate cooling, contamination from leakage through can seams and pre-process spoilage. In under-processed cans (receiving low heat treatment), large number of different types of micro-organisms are expected to be involved in spoilage.
Causes of Food Spoilage
Food spoilage or deterioration may be described as loss of weight, softening, souring, rotting, wilting, moulding or a combination of one or more forms. The major causes of food deterioration are: biotic and abiotic factors.
A. Biotic Factors
1) Microbial spoilage (yeast, mould, bacteria)
2) Enzyme action (activities of enzymes present in foods)
3) Insect and rodent damage (attack of insects, rodents and parasites)

Mutation breeding is a method that uses physical radiation or chemical means to induce genetic variation in plants to develop new crop varieties. Mutation can be defined as a sudden heritable change in the character of an organism which is not due to either segregation or recombination. Mutation is the source of most genetic variation and the motor of evolution. It is a natural process, which occurs spontaneously and slowly over generations in plants, animals and all living beings. It involves alteration of their DNA, leading to the development of changes within the organism. Mutation may be sped up through the treatment of physical or chemical mutagens to achieve alteration in characteristics that are useful for the development of new variety of a plant species.
Spontaneous mutations
Spontaneous mutations are the net result of all that can go wrong with DNA during the life cycle of an organism (Glickman et al., 1986). Thus, the types and amounts of spontaneous mutations produced are the resultant of all the cellular processes that are mutagenic and those that are anti-mutagenic. Spontaneous mutations occur naturally without any apparent cause however, there are two possible sources of origin of these mutations.

High temperature stress
Abiotic stresses either individually or in combination cause morphological, physiological, biochemical and molecular changes that adversely affect plant growth and ultimately yield. The major forms of abiotic stress plants are exposed to in nature are heat, drought, cold and salinity. Of these abiotic stresses, heat stress has an independent mode of action on the physiology and metabolism of plant cells. High temperatures above optimal have generally damaging effects on plant development which has led to the prediction that Global warming have a negative effect on plant growth. High temperature regimes may cause severe yield reduction leading to even famine. High temperature stress has wide range of effects on plant in terms of physiology, biochemistry and gene regulation pathways. The susceptibility to high temperatures in plants varies with the stage of plant development and genotype.
Mechanisms of heat tolerance
Heat tolerance is generally defined as the ability of the plant to grow and produce economic yield under high temperature conditions. Several plant physiological parameters and mechanisms that contribute to heat tolerance in the field include:

Intellectual Property Rights (IPR)
There are two types of properties viz., i) Tangible, physical or material property and ii) Intangible or intellectual property. Intellectual property (IP) pertains to any original creation of the human intellect such as artistic, literary, technical or scientific creation. The tangible or physical properties are protected by the laws of land. In contrast, intellectual property is an idea, a formula, an invention, a design, a variety, etc. which= may give rise to a useful product. For obvious reasons the inventors would like to be rewarded and their inventions be protected from imitation. Such a right of an inventor to obtain economic benefit and protection of the invention from imitation is known as Intellectual Property Right (IPR). Thus, Intellectual property rights (IPR) refers to the legal rights given to the inventor or creator to protect his invention or creation for a certain period of time (Singh, 2008).
Why Intellectual Property needs to be protected?
Intellectual property rights (IPR) encourage innovation and protect the rights of the inventors in legalized form. It is an inevitable tool in today’s globalized economy. The invention of such things would require intellectual capacity, innovativeness and creative ability of the concerned person(s).

Sweet pepper or bell pepper, a cultivar group of the species Capsicum annuum under the family Solanaceae (Chromosome No. 2n =2x =24) is grown worldwide as green vegetable for its thick and fleshy fruits having delicate taste, pleasant flavour and colour. Sweet pepper requires slightly cooler climate than hot chillies. The fruits are generally non-pungent hence, it is commonly known as sweet pepper. It is also popular as bell pepper because of blocky fruit shape. China is the largest producer of sweet pepper in the world.
Origin, domestication and adaptation in India
Hot chillies and sweet pepper have originated from the wild and weedy species Capsicum annuum var. minimum whose domestication occurred in Mexico and distributed from the southern United states to northern south America. Domestication, cultivation and human selection brought about changes in fruit size and shape and fruit position from erect to pendant. It also resulted in more self-pollinating character due to inserted stigma unlike the exserted stigma in the wild types.

Cucumber, Cucumis sativus under the family Cucurbitaceae (Chromosome No: 2n = 2× =14) is grown throughout the world for consumption of fresh and tender fruits as slicing cucumber, and for pickles as pickling cucumber. Slicing cucumbers are usually larger and have thicker skins, while pickling cucumbers are usually smaller and have thinner skins. The flesh of cucumbers is rich vitamin C, and folic acid, fibre and a range of minerals including magnesium, molybdenum and potassium.
Origin, domestication and adaptation in India
The genus Cucumis, which includes cucumber (Cucumis sativus) and melon (Cucumis melo), has numerous wild African species, and it has therefore been assumed that
melon originated in Africa. For cucumber, this seemed less likely because wild cucumbers exist in India and a closely related species, Cucumis hystrix is available in the Eastern Himalayas. Using DNA sequences from plastid and nuclear markers for some 100 Cucumis accessions from Africa, Australia, and Asia, Sebastian et al (2010) concluded that melon and cucumber are of Asian origin and have numerous previously overlooked species-level relatives in Australia and around the Indian Ocean.

Cucumbers, muskmelons, watermelons, squashes, gourds, and pumpkins are commonly grown cucurbits in most parts of the world. Cucurbitaceous crops are the most important summer vegetables grown all over the world and it includes 118 Genera and 825 Species. Production and productivity of cucurbits are affected by the incidence of pests and diseases. Important pests attacking cucurbits are fruit fly, snake gourd semilooper, red pumkin beetles, hadda beetles/ epilachna beetles, pumkin caterpillar, vine borer/ clear winged moths, gall fly, serpentine leaf miner, shield bug, snake gourd bug and plume moth.
The melon fruit fly is distributed widely in temperate, tropical and subtropical regions of the world. It has been reported to damage 81 host plants and is a major pest of cucurbitaceous crops. The extent of loss varies between 30 –100 per cent depending on the cucurbit species and season. The adult is reddish brown with lemon yellow curved vertical markings on the thorax and fuscous shading on the outer margin of wings.
Biology: Eggs are white and cylindrical and laid singly or in clusters in cavities made with the ovipositor of the females on the fruits. The holes are sealed with gummy secretions, which solidify to form a shiny brown resinous material. Egg period is 1 to 2 days. The emerging maggots are apodous, dirty white, thicker at one end and tapering at the other and are seen within the fruits. Larval period is 7 days. The mature larvae emerge from the fruits and pupate in soil for a period of one week. Life cycle is completed in 15 to 20 days.

Okra, commonly known as lady’s finger is a significant vegetable crops primarily grown in tropics and subtropics. Production and productivity of okra is affected by the incidence of pests and diseases. More than 70 insect pests have been recorded in okra (Ewete, 1978).
Biology: Forewings of the moth white with a pea- green wedge-shaped band running medially from base to outer margin of each wing. Eggs are laid on tender parts of the plant, leaf axils, bracts, leaf veins, buds, flowers and fruits singly or in two’s or threes. Egg period - 3-4 days. Caterpillars are brownish with median longitudinal streak dorsally and pale yellow or green ventrally. Larval period is 2 weeks. Pupae are seen on the plant in dirty white boat shaped cocoons made of silk. Pupal period is one week. The life cycle is completed in about a month.
Nature of damage and Symptoms
The newly hatched larvae bore into the terminal shoots or fruits. The damaged shoots droop, wither and dry up. The infested fruits are deformed with holes on them plugged with excreta.

Introduction
Temperature regulation is a critical physiological process that allows animals and birds to maintain homeostasis in varying environmental conditions. Thermoregulation involves a complex interplay of behavioral, physiological, and biochemical mechanisms that ensure the body temperature of these animals remains within a narrow, optimal range. This process is vital for maintaining metabolic functions, health, and productivity, particularly in agricultural settings where animals are often exposed to temperature extremes.In farm animals such as cattle, sheep, and pigs, thermoregulation is primarily managed through a combination of heat production, heat dissipation, and behavioral adaptations. Endothermic animals generate heat internally through metabolic processes, particularly in the muscles and liver. This heat is distributed throughout the body via the circulatory system. When ambient temperatures rise, farm animals activate various cooling mechanisms to prevent hyperthermia. These mechanisms include increased respiratory rates (panting), sweating (in species like cattle and horses), and vasodilation, where blood vessels near the skin surface expand to dissipate heat. Conversely, in cold environments, animals reduce heat loss by vasoconstriction, piloerection (raising of hair or fur), and seeking shelter or huddling together. Behavioral adaptations, such as seeking shade or water, also play a crucial role in temperature regulation.In poultry, thermoregulation is equally important but is managed differently due to their unique physiology. Birds lack sweat glands and have a higher metabolic rate compared to mammals, which means they rely more heavily on respiratory evaporative cooling and behavioral adaptations. Poultry regulate their body temperature by panting, which increases evaporative heat loss from the respiratory tract. Additionally, birds adjust their posture, such as spreading their wings or ruffling feathers, to enhance heat dissipation. During cold stress, poultry increase their metabolic rate, fluff their feathers to trap air for insulation, and reduce blood flow to peripheral areas to conserve heat. The thermal comfort zone, or thermoneutral zone, is narrower in poultry compared to larger mammals, making them more susceptible to temperature extremes.The ability of farm animals and poultry to regulate their body temperature is influenced by several factors, including age, breed, body condition, and acclimatization to the environment. Younger animals and certain breeds are more vulnerable to temperature stress due to their less developed thermoregulatory mechanisms or specific genetic traits. For instance, breeds with higher muscle mass or thicker coats may be more prone to heat stress, while those with lower body fat reserves may struggle in cold conditions. Acclimatization, or the gradual adaptation to a new thermal environment, plays a key role in enhancing the thermoregulatory capacity of these animals.

Introduction
In the intricate tapestry of life, the relationship between foodstuffs and animal nutrition forms a fundamental thread, weaving its way through the intricate patterns of ecological balance, agricultural practices, and the sustenance of diverse life forms. The intersection of these two realms is not only pivotal for the flourishing of animals but also crucial for the well-being of ecosystems, human societies, and the planet at large. This intricate connection delves into the nuanced interplay between dietary components, physiological mechanisms, and the broader implications for the health of animals, both domestic and wild.
It is imperative to recognize that foodstuffs are not mere sustenance; they are the building blocks of life, the fuel for growth, and the source of energy that sustains the diverse array of creatures inhabiting our planet. From the microscopic organisms in the soil to the majestic mammals roaming vast landscapes, the quest for nourishment is a universal constant, intricately tied to the delicate balance of ecosystems.
At the heart of this relationship lies the fascinating science of animal nutrition—a field that scrutinizes the complex interactions between dietary elements and an organism’s physiological functions. From the intricacies of nutrient absorption to the role of different foodstuffs in promoting health, animal nutrition serves as a compass guiding us through the intricate pathways of biology, agriculture, and environmental conservation. The journey into understanding animal nutrition commences with a closer look at the varied foodstuffs that contribute to the dietary landscape. Foodstuffs, in this context, encompass a vast array of substances ranging from grains and forage to proteins and fats, each playing a distinctive role in the nutritional well-being of animals. The composition and quality of these foodstuffs are crucial determinants of an animal’s growth, reproduction, and overall
health. Unraveling the nutritional value of these components requires delving into the realms of biochemistry, physiology, and the intricate dance between macronutrients and micronutrients.
Macroscopic entities such as carbohydrates, proteins, and lipids stand as the pillars of animal nutrition. Carbohydrates, in the form of sugars, starches, and fibers, serve as the primary source of energy, fueling the metabolic processes that sustain life. Proteins, comprising amino acids, are the essential building blocks for growth, development, and the maintenance of bodily functions. Meanwhile, lipids, including fats and oils, play
multifaceted roles, serving as energy reserves, structural components, and facilitators of nutrient absorption.

Introduction
Heart failure can develop as a complication of almost all congenital and acquired cardiac diseases in dogs and cats. Cardiac disease is a significant global health concern, impacting both humans and domestic animals, particularly dogs. In the animal kingdom, the cardiovascular system consists of essential components, including the heart, veins, arteries, and capillary beds. Its proper function depends on complex mechanisms, such
as the atrioventricular valves (mitral and tricuspid) and the semilunar valves (aortic and pulmonic), which ensure that blood flows in only one direction through the heart. The activity of the cardiovascular system, including heart contraction rates and strengths, as well as blood vessel diameter adjustments, is regulated by the autonomic nervous system (both sympathetic and parasympathetic branches) and various hormones.
The strength of ventricular contractions is influenced by several factors, primarily enddiastolic volume (preload) and myocardial contractility (inotropy). Preload is the amount of blood in the ventricles just before they contract, while contractility refers to the ability of the heart muscle fibers to contract. Preload is determined by the difference between the end-diastolic pressure in the ventricle and the pressure in the pleural space, adjusted for the
stiffness of the ventricular myocardium. This pressure is influenced by the ratio of blood volume to the heart muscle’s compliance. Low-pressure volume receptors in the heart and large veins primarily regulate preload. When these receptors detect increased blood volume or vein distension, they trigger responses such as increased urine production and vein dilation, which help reduce blood volume and lower venous pressures. Increased enddiastolic volume (preload) stretches the ventricular wall, enhancing contraction strength through the Frank-Starling mechanism, or Starling’s law of the heart. This stretching activates receptors in the atria and ventricles, leading to the release of natriuretic peptides like brain natriuretic peptide (BNP) from the ventricles and atrial natriuretic peptide (ANP) from the atria) These peptides promote natriuresis, relax smooth muscle, and counteract
vasopressin and angiotensin II. In dogs, levels of BNP and NT-proBNP are directly related to cardiac stretch.

Introduction
In cattle, the digestive system consists of four primary compartments: the rumen, reticulum, omasum, and abomasum, followed by the small and large intestines. The rumen plays a crucial role as a fermentation chamber, maintaining anaerobic conditions and ensuring thorough mixing, as well as regulating temperature and pH levels. Food, which is frequently re-chewed, enters the rumen through the esophagus, where fermentation occurs.
The byproducts of fermentation are either absorbed within the rumen or moved on for further digestion and absorption in other parts of the digestive system. Simple indigestion in ruminants is a temporary disruption in gastrointestinal function, usually caused by a sudden change in the quality or quantity of their diet. Consuming large amounts of indigestible feed can impair rumen function for 24 to 48 hours after ingestion, as the accumulation of this feed can physically disrupt ruminal activity. Additionally, the breakdown of proteins in the rumen can produce toxic substances such as amides and amines, including histamine. This condition can lead to a significant drop in milk production due to a marked reduction in the production of volatile fatty acids in a hypotonic reticulorumen. Ruminal impaction is a condition seen in ruminants like cows, sheep,and goats, where the  rumen’s contents become compacted, obstructing their movement through the digestive tract. This condition can arise from various causes, including the ingestion of plastic waste, grazing habits, mineral deficiencies, negative energy balance, urbanization, inadequate water intake, low-fiber or high-grain diets, changes in feed or grazing patterns, and stress. The accumulation of foreign material can block fermentation, interfere with the mixing of rumen contents, and disrupt the rumen’s microflora, leading to indigestion. Acute ruminal acidosis is often caused by the sudden intake of large amounts of carbohydrate-rich feed, particularly grains. Subacute ruminal acidosis (SARA) occurs in dairy cattle and is characterized by disrupted ruminal fermentation. It typically results from feeding large amounts of concentrates with insufficient fiber, a practice often used to boost milk production during early lactation. This imbalance in diet can disturb rumen pH and microbial populations, leading to various metabolic and digestive problems. Chronic ruminal acidosis can lead to complications such as rumenitis, which is inflammation of the rumen, and laminitis, a painful condition affecting the hooves. Alkaline indigestion, also known as ruminal alkalosis, occurs when the pH of ruminal fluid rises above 7.5.
 

Introduction
Respiratory diseases are a common clinical issue in dogs, particularly in those housed in environments like pet shops, shelters, breeding and boarding kennels. Puppies and senior dogs are at a higher risk of developing respiratory infections compared to adult dogs. The respiratory system is one of the body’s four major systems, comprising the upper airways (pharynx, larynx, and trachea and the lower airways (bronchi, bronchioles, and
alveoli). The pharynx, which serves as a common passageway for both the respiratory and gastrointestinal systems, explains the relatively high incidence of aspiration pneumonia. The luminal diameter of the pharynx is the widest, followed by the larynx and trachea.
The ratio of tracheal diameter to thoracic inlet height (TD:TI) remains relatively constant, regardless of the animal’s size or respiratory phase. The respiratory tract is typically protected from harmful pathogens by physical, chemical, and immunologicbarriers, including mucus, mucociliary clearance, innate antimicrobial factors, alveolar macrophages, and the pulmonary immune response. The entire respiratory tree is lined with ciliated epithelial cells, except for the bronchioles, which are lined by non-ciliated granular secretory cells known as club cells. The respiratory system’s primary function is achieved through four major processes: pulmonary ventilation; diffusion of oxygen and carbon dioxide between the alveoli and the blood; transport of these gases in the blood and body fluids to and from the body’s tissue cells; and regulation of ventilation and other respiratory factors. The pulmonary alveoli, the main sites for gas exchange between air and blood, are highly vulnerable to injury if the body’s defense mechanisms are compromised, underscoring the importance of prompt emergency treatment for respiratory diseases

The chief functions of Clinical Microbiological laboratory are to examine and culture specimens for microorganisms, to make accurate species identification of important isolates and to perform antibiotic susceptibility tests when indicated. These tasks will assist physicians in the diagnosis and treatment of infectious diseases.

Once the specimen is received in the laboratory, the specimens are examined visually depending on the physicians order and the nature of the specimen. Wet mounts and smears may be prepared and stained for microscopic examination. Observations may or may not be immediately reported to the physicians depending on the definitiveness of the results. Timely information may often be used to establish a presumptive diagnosis and institute a specific course of therapy. Specimens that require definitive identification of potentially pathogenic microbes are processed further. All agar plates are streaked for colony isolation; then plates and broths. All cultures are placed in an incubator with appropriate temperature and environmental conditions to maximize the growth and replication of microbes. Often a presumptive microbial identificationcan be made. A final report should be delayed while subcultures and additional test procedures are performed to identify the organisms definitively.

Preliminary Identification of Unknown Bacteria
A number of techniques may be used in the direct microscopic examination of clinical specimens to demonstrate the presence of microbes The examination of wet mounts of unstained materials by phase contrast or
dark field microscopy is useful for demonstrating motility, spirochaetes and endospores. Giemsa, Wright or acridine orange stains may be helpful in observing bacterial forms that stain poorly or that have little contrast from
back ground material.

Abstract
Biological nitrogen fixation (BNF) is a critical ecological process carried out by grain legumes, which form symbiotic associations with nitrogen-fixing bacteria, primarily Rhizobium species. This natural mechanism converts atmospheric nitrogen (N2) into ammonia, a form that plants can readily utilize, significantly enhancing soil fertility and reducing the need for synthetic nitrogen fertilizers. The process begins with the recognition and infection of the legume roots by rhizobia, leading to the formation of specialized structures called nodules, where the bacteria convert atmospheric nitrogen into ammonia through the enzymatic action of nitrogenase. The symbiosis between legumes and rhizobia is tightly regulated by various genetic and environmental factors, including plant signalling molecules, soil conditions, and nutrient availability. Grain legumes, such as soybeans, chickpeas, and lentils, play a vital role in sustainable agriculture by improving soil health, promoting biodiversity, and providing a protein-rich food source. This overview explores the molecular mechanisms underlying BNF, the factors influencing the efficiency of this process, and its potential to enhance sustainable agricultural practices. Understanding the intricacies of BNF in grain legumes can inform breeding programs and management strategies aimed at maximizing the benefits of this natural process for agricultural productivity and environmental sustainability.

Abstract
Grain legumes, members of the Fabaceae family, are essential for global nutrition and sustainable agriculture. The legumes such as soybean, chickpea, lentil, pigeon pea, black gram, green gram, faba bean and field peas are renowned for their high protein and energy content. A core aspect of their significance lies in their ability to fix atmospheric nitrogen through symbiotic relationships with Rhizobium bacteria, enhancing soil fertility and reducing the need for synthetic fertilizers. This process, coupled with their role in carbon sequestration, positions legumes as crucial components of sustainable farming systems. Grain legumes, as C3 plants, rely on efficient carbon assimilation to convert atmospheric CO2 into biomass, supported by high nitrogen content for optimal photosynthesis. Additionally, the symbiotic nitrogen fixation within root nodules enables legumes to transform atmospheric nitrogen into forms usable by plants, thereby contributing to soil nitrogen pools and reducing greenhouse gas emissions. By integrating
legumes into crop rotations, farmers can enhance soil health, lower fossil energy inputs, and support ecological sustainability. This comprehensive analysis underscores the critical roles of carbon and nitrogen assimilation in maximizing the environmental and agronomic benefits of grain legumes.

Abstract
Grain legumes, a group of crops which belong to Fabaceae family, are primarily grown for their edible seeds. Pulses contain a high amount of protein (20-25%), vitamins, and minerals. Consumption of pulses can be beneficial for cardiovascular health, weight management, for diabetics, cancer management, bone health etc. So, grain legumes can play a significant role to address future global food security, environmental sustainability, and nutritional needs. The nutritional value of grain legumes can be significantly enhanced through biofortification, agronomic intervention, processing, and value addition. So, diversification of food habit with pulses and cereals can solve the prolong problem of malnutrition in developing countries including India. Despite such great importance, global food legume production has
been found to increase at a very slow pace. Keywords: Biofortification, Environmental sustainability, Food security, Grain legumes, Nutritional security
Introduction
Grain legumes or pulses are a group of crops which belong to family Fabaceae, are primarily grown for their edible seeds. The common examples of grain legumes include: bean (Phaseolus spp.), lentil (Lens culinaris), chickpea (Cicer arietinum), pea (Pisum sativum), soybean (Glycine max), lupin (Lupinus spp.), broad bean (Vicia faba), igeon pea (Cajanus cajan), grass pea (Lathyrus sativus), black gram (Vigna mungo), green gram (Vigna radiata). Grain legumes can play a significant role to address future global food security, environmental sustainability, and nutritional needs. Pulses are the second most important food crop after cereals and an important source of proteins, vitamins, and minerals. Pulses are popularly known as “Poor man’s meat” and “Rich man’s vegetable”. Pulses contain a high amount of protein (20-25%), which is almost double and triple of the protein content of wheat and rice, respectively and so can contribute significantly to the nutritional security of the country. Besides, they may serve the purpose of protein rich fodder and good quality green manure crop. Pulses can thrive well in low and marginal land with less external inputs. They act as erosion resisting crops because of its deep tap root
system, leafy growth, and close spacing. Pulses can also be grown as paira crop or inter-crop in different growing situations. Being a leguminous crop, it can fix atmospheric nitrogen with the help of its root nodules, resulting in low requirement of external fertilizer. Keeping the importance of pulses in mind, United Nation’s Food and Agricultural Organization (FAO) also declared 2016 as the ‘International Year of Pulses’.

Abstract
The United Nations predicts that by 2050, the global population will reach 9.6 billion, leading to urgent challenges such as ensuring food security and reducing greenhouse gas emissions. Climate change, coupled with biotic and abiotic pressures, will significantly impact global food production. Despite advances in agriculture, malnutrition remains a widespread issue, affecting millions, especially in developing countries. Protein-energy malnutrition, which affects over 170 million children and women, poses a significant threat to national economic development, increasing healthcare costs and reducing productivity. One key solution to combating malnutrition lies in promoting legumes (pulses), which are nutrient-dense, protein-rich, and vital for both human and animal consumption. Pulses have been a staple in diets
for centuries, providing essential nutrients like protein, fiber, vitamins, and minerals. They are not only beneficial for human health, reducing the risk of heart disease, diabetes, and cancer, but they also contribute to sustainable agriculture. Legumes can fix atmospheric nitrogen, reducing the need for synthetic fertilizers, improving soil health, and increasing agricultural productivity. However, despite their benefits, pulse production lags behind other staple crops like cereals. With proper management, legumes could play a vital role in alleviating global hunger, particularly in developing countries. Increased awareness and efforts to incorporate legumes into farming systems and daily diets could help meet the growing global demand for nutritious, sustainable food.

Abstract
Food insecurity and malnutrition are on the rise globally, impacting millions, especially in rural regions where extreme poverty and food insecurity are deeply rooted. Vulnerable groups, including women, youth, and indigenous peoples, are disproportionately affected. Producing foo  that meets dietary needs and ensuring its availability in the future is essential for sustainable development and food sustainability. Addressing the growing global food security concerns and supporting the increasing population requires the continual expansion of plant-based proteins’ significance. Legumes are excellent sources of proteins, carbohydrates, and both soluble and insoluble dietary fibers. Legumes, with their high dietary fiber and low-fat content, help maintain body weight and lower the risk of cardiovascular disease. They are also rich in essential minerals such as potassium, calcium, magnesium, phosphorus, and iron, and provide important vitamins like folate, thiamine (B1), riboflavin (B2), and niacin (B3). Additionally, pulses contain various phytochemicals, including phenolics, flavonoids, phytates, lectins, tannins, saponins, oxalates, enzyme inhibitors, phytosterols, and antimicrobial peptides, which offer numerous potential health benefits. These phytochemicals exhibit anti-inflammatory, anticancer, antimicrobial, and anti-ulcerative properties. Incorporating legumes into agricultural systems can foster more sustainable and climate-resilient farming practices. In developing countries, legumes are often used to supplement cereals or starchy foods to combat protein-energy malnutrition, as animal proteins tend to be expensive in these regions.

Abstract
India shares one fourth of global annual grain legume production and is also largest consumer of it. Weeds are the most severe and widespread biological constraint on agricultural production systems and cause damage to cropped and non-cropped lands. They reduce crop yield and degrade the quality of the produce, besides raising the cost of production. The grain legumesare commonly grown under rainfed/dry land conditions and hence do not receive the best management practices that are required for maximization of crop productivity. Among various production inputs, weed management was found to be the most important one contributing about 31% in pigeon pea, 110% in urdbean and 60 % in mungbean towards total productivity. Effective weed management in grain legumes is essential for optimizing
crop yield and quality. This process involves a multi-faceted approach that integrates cultural, mechanical, and chemical methods to address the challenges posed by diverse weed species and varying environmental conditions. Traditional single-method approaches often fall short due to the complexity and variability of weed problems like development of resistance in weeds. Therefore, an integrated weed management approach becomes effective, combining timely interventions with adaptive strategies to manage weed competition throughout the growing season. This approach not only enhances crop competitiveness and yield but also offers economic and environmental benefits by reducing reliance on broad-spectrum herbicides and promoting sustainable practices. Continuous monitoring and adjustment
of weed management strategies are crucial to effectively tackle evolving weed populations and changing conditions, ensuring long-term success in grain legume cultivation.

Introduction
In a host-parasite relationship, the interaction between the two organisms is highly specialized. Each partner impacts the other’s life by influencing their metabolism and behavior through various adaptive mechanisms, all aimed at ensuring their own survival. While the parasite exerts every effort to fully establish itself within the host—by consuming its resources, damaging its tissues, secreting toxins, and evading the host’s immune
system through molecular mimicry—the host, in turn, strives to eliminate the parasite by mobilizing its immune defenses.
Despite their ongoing conflict, neither the host nor the parasite is able to completely eradicate the other. The host seeks to fend off the harmful, invasive parasite, while the parasite aims to establish a lasting, close relationship with the host. However, this dynamic can lead to a point where either the host or the parasite, often the parasite, becomes dominant or independent, resulting in the death of one party. Thus, the host-parasite relationship appears to be a perpetual and interdependent one, each partner intricately tied to the other. When a parasite enters a host, the host must make adjustments, and the parasite must adapt
to the host’s environment. This interaction leads to the development of a relationship in which both the host and the parasite influence each other’s growth, metabolism, and overall well-being. Generally, the host-parasite relationship unfolds through a series of stages: it starts with the transmission of the parasite from one host to another, followed by the parasite’s distribution and localization within or on the new host. This is followed by the
parasite’s growth or multiplication. Throughout this process, both the host and the parasite engage in resistance efforts against each other. The process involves several stages: the parasite’s method of attack, the changes the parasite induces in the host, and the alterations the parasite undergoes due to its presence in the host. It also includes the adjustments made by both host and parasite during the infection, the escape of the parasite’s infective stages from the host, and ultimately, the host’s recovery or death

Introduction
Animal behavior, a fascinating field of study, encompasses a wide range of activities and responses to internal and external stimuli. Among the various factors that shape these behaviour’s, hormones and drugs are particularly significant. These biochemical agents profoundly influence the physiological and psychological aspects of animals, leading to observable changes in their behaviour. This introduction explores the roles of hormones and drugs in animal behavior, detailing their mechanisms, effects, and implications for broader scientific understanding and practical applications. Hormones and drugs play vital roles in shaping animal behavior through complex biochemical pathways. Hormones act as internal regulators, orchestrating responses to environmental and physiological changes, while drugs, whether therapeutic or environmental, modulate these processes, often with profound behavioral consequences. Understanding these influences is crucial for advancing animal welfare, conservation efforts, and biomedical research, ultimately enriching our comprehension of the intricate relationship between biology and behavior in the animal kingdom.
Hormones and Animal Behaviour Deliver
Hormones are chemical messengers produced by endocrine glands and secreted into the bloodstream, where they travel to target organs and tissues, eliciting specific physiological responses. These responses, in turn, influence behaviour. The following are some key hormones that play critical roles in animal behavior:
1. Corticosteroids
• Function: Corticosteroids, such as cortisol in mammals and corticosterone in birds and reptiles, are released by the adrenal glands in response to stress.
• Behavioral Impact: They prepare the body for the fight-or-flight response, affecting behaviour’s related to fear, anxiety, and aggression. Chronic stress exposure and elevated corticosteroid levels can lead to long-term behavioral changes, including heightened anxiety and altered social interactions.

Abstract
Aquatic ecosystems are seriously threatened by heavy metal pollution from urban, agricultural, and industrial processes. Aquatic animals can accumulate toxic metals like mercury, lead, cadmium, arsenic and chromium, which can have detrimental physiological, ecological, and toxicological impacts. Oxidative stress, organ damage, poor reproduction, and disruption of ecosystem functioning, including loss of biodiversity and changes in food web dynamics, can all result from exposure to these contaminants. Human health is also at risk from heavy metals moving via aquatic food networks. The effects of heavy metal pollution on aquatic life are examined in this chapter, along with mitigation strategies.

Introduction
Diabetes mellitus is a disease the related to metabolism of the body and malfunctioning of pancreas. Pancreas having alpha and beta cells where alpha cells produce enzymes needed for the digestion and beta cells mainly produce insulin. One important component that regulates blood glucose (sugar) levels and how it is delivered to the body’s cells is Insulin. The body’s cells run out of their primary energy source when insulin levels are low. Insulin voices the body’s cells to engross glucose from the bloodstream. Without an satisfactory amount of insulin glucose cannot invade the cells and so it accrues in the blood, triggering hyperglycemia (high blood sugar). In retort to this ostensible starvation, the body starts flouting down supplies of protein & fat for energy, producing weight loss contempt a ravening appetite. The body efforts to remove the extra glucose by micturating. To avoid thirst, the dog drinks more and more water. Type I increased diabetes mellitus outcomes from completeobliterat ion of the insulin-creating beta cells. In dogs, this is the most prevalent kind of diabetes. As the name implies, insulin injections are necessary to balance blood sugar in dogs with this kind of diabetes.

Viral Diseases in Domestic Animals
Viral diseases significantly impact the health and productivity of domestic animals, including livestock and companion animals, leading to substantial economic and emotional costs. In livestock, diseases like Foot-and-Mouth Disease (FMD) and Peste des Petits Ruminants (PPR) cause severe production losses in terms of milk, meat, and wool. Similarly, in poultry, Newcastle disease and Avian Influenza outbreaks result in high mortality and disruptions to egg production. Among companion animals, viruses such as Canine Distemper and Feline Leukemia Virus (FeLV) lead to serious morbidity and reduced quality of life. Current control measures rely heavily on vaccination and biosecurity practices, but the lack of effective antiviral treatments, coupled with the emergence of drug-resistant strains, underscores the need
for novel therapeutic approaches. Medicinal plants with antiviral properties have garnered significant interest as sustainable and holistic solutions. Plantderived bioactive compounds offer a dual advantage of modulating immune responses and directly targeting viral pathogens, making them a promising area of research for the management of viral diseases in both livestock and pet animals.

Cardiovascular System Disorders in Domestic Animals
Cardiovascular system disorders in domestic animals include a range ofM conditions that affect the heart (pericardium, myocardium, endocardium), veins, arteries and lymphatic vessels. Infectious disorders like Heartworms (Dirofilaria immitis, vegetative endocarditis in pigs, equine viral arteritis). Patency of the foramen ovale, interventricular foramena, patent ductus arteriosus, persistence of the right aortic arch, coarctation of the aorta, transposition of the aorta, congenital aneurysm, pulmonic stenosis, subaortic stenosis, ectopia cardis, acardia, and diplocardia are examples of congenital and developmental disorders that can result in these conditions. Traumatic disorders like Traumatic reticulopericarditis and cardiac failure. Degenerative diseases like fatty and hyaline degeneration. Inflammatory disorders like pericarditis,
myocarditis, endocarditis and phlebitis may also lead to cardiovascular system disorders. Some tumours associated with the cardiovascular system like rhabdomyosarcoma, fibroma and myxofibroma also cause cardiovascular system disorders.

Abstract
Single-cell proteins (SCPs) have gained huge attention in the aquafeed industry as a suitable alternative to traditional protein sources, including fish meal and soy protein. SCPs obtained from the algae, bacteria, fungi, and yeast often contain high protein content and superior amino acid profiles. The presence of essential fatty acids and additional bioactive compounds further support their role as adequate replacements for the current protein sources. Among those, mycoproteins are currently a major area of interest due to their favourable nutritional profile, higher growth rates and efficient production process. These have the ability to use a variety of agricultural and industrial by-products as their feedstocks. PEKILO® protein is such a commercial mycoprotein obtained from carbohydrates containing lignocellulosic wastes from forestry by-products. It was produced from the fungal species Paecilomyces variotii from the substrates such as spent sulphite liquor and molasses through a continuous fermentation process. Pekilo protein consists of 60 to 70% crude protein content, essential amino acids, vitamins, minerals, β-glucans and nucleotides. Its high digestibility and amino acid content make it a suitable protein source for the aquafeed industry. Recent research studies suggest that pekilo protein has a high potential as a non-conventional protein source in commercial salmon and shrimp feeds. Being a sustainable alternative to fishmeal, pekilo protein can help reduce the future challenges of fish meal supply and long-term sustainability.
Keywords: Pekilo protein, Mycoprotein, Non-conventional ingredient and Single-cell protein.

Abstract
The development of aquaculture from its prehistoric beginnings to a highly developed, international sector emphasizes the need for cutting-edge equipment to guarantee sustained production. Passive Integrated Transponder (PIT) tagging is a cornerstone for selective breeding programs, enabling precise monitoring and managing aquatic species. PIT tags, tiny electronic microchips implanted into fish, offer a reliable and durable method for individual identification without affecting species growth or survival. Their versatility extends across various applications, from studying migration and behaviour to monitoring genetic traits critical for breeding. PIT tagging stands out due to its simplicity, cost-effectiveness, and compatibility with various aquatic environments. PIT tags offer a long-term solution with less interference than external tags, which are more likely to be lost or damaged. Technological advancements have refined PIT tagging, allowing its application even in small-bodied fish, thus broadening its utility in ecological and genetic studies. These tags also play a pivotal role in reducing inbreeding in hatcheries by maintaining precise genetic records. Despite the proven benefits, PIT tagging requires careful consideration of fish species, size, and environmental factors to optimize tag retention and ensure minimal stress. Advancements in tagging techniques, such as improved surgical techniques and new equipment for tag implantation further increase the dependability of this technology. Studies confirm that PIT tagging has negligible effects on fish physiology and behaviour, making it an indispensable tool in aquaculture research and management. The aquaculture sector can enhance broodstock quality, guarantee genetic diversity, and tackle climate change issues by incorporating PIT tagging into selective breeding strategies. This technology not only supports the production of high-quality seed stock but also aligns
with sustainable aquaculture practices, ensuring the long-term viability and growth of the industry.

Abstract
The growing demand for fish products, recognized for their nutritional composition and contribution to a healthy diet, has led to a significant increase in seafood processing waste, including shells, bones, skins, and other by-products. This chapter explores the potential of utilizing these seafood by-products to develop edible films and coatings, aligning with circular bio economy principles of, resource efficiency, sustainability and waste reduction. Edible films and coatings derived from seafood waste, such as chitosan, proteins, gelatin etc. offer various advantages, which include extention of the shelf life of products, preserving sensory qualities (aroma, taste, and appearance), and reducing the need for synthetic packaging materials. These biodegradable films also demonstrate antimicrobial, antioxidant, and mould-inhibiting properties, which contribute to improving food quality and safety. However, despite the benefits, challenges remain in terms of the physical properties of these films, including water resistance, mechanical strength, and consumer acceptance. The commercial application of these biopolymer-based materials is still limited by these issues, as well as by the complexities involved in scaling up production processes. To optimise the qualities of edible films and coatings made from seafood waste, more research is essential, particularly through the development of composite materials and innovative gelling systems. With ongoing advancements in biopolymer technology and processing techniques, edible films from seafood waste hold great promise as a sustainable, eco-friendly alternative to traditional plastic packaging, contributing to the circular bio economy and reducing environmental pollution.

Introduction
Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse.
UNEP defines Environmental Impact Assessment (EIA) as a tool used to identify the environmental, social and economic impacts of a project prior to decision-making. It aims to predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment and present the predictions and
options to decision-makers.
Environment Impact Assessment in India is statutorily backed by the Environment Protection Act, 1986 which contains various provisions on EIA methodology and process.
Evolution & History of EIA
EIA is termed as one of the best policy innovations in the 1900s. The main aim of EIA is to conserve the environment and bring out the best combination of economic and environmental costs and benefits. Read the below-mentioned points to understand the Environmental Impact Assessment evolution and history:
• The birth of EIA is dated back to the 1970s.

Policy research plays a critical role in influencing policy change by generating robust evidence that can guide decision-making processes. The use of evidence is crucial in ensuring that policies are both effective and appropriate to address specific issues. Evidence-based policy-making relies on credible, relevant and timely research that helps identify problems, evaluate potential solutions and
forecast the impacts of various policy options.
Role of Policy Research in Generating Evidence
1. Identification of issues: Policy research begins with identifying key issues or challenges that require policy intervention. This involves conducting systematic research to understand the scope, scale and
nature of the problem. For example, research on gender disparities in agricultural labor in India may highlight specific barriers women face, such as lack of access to resources or discriminatory practices.
2. Data collection and analysis: Gathering quantitative and qualitative data is essential for building a comprehensive understanding of the issue. For instance, data collection may involve surveys, interviews,
case studies and secondary data analysis to capture diverse perspectives and experiences. This data provides a solid foundation for analyzing the problem’s root causes and identifying the affected population.

19.1 Introduction
Mulberry silkworm, Bombyx mori, is affected by a number of diseases caused by viruses, bacteria, fungi and protozoa. These illnesses are recognized to occur in practically every region where silkworms are raised in the world seriously harming the harvest of silkworm cocoons. Several actions have been proposed as a means of preventing and managing the illnesses, but none of them had shown signs of foolproof with the outcome that one must consistently be cautious to eradicate the core infection’s source in addition to avoiding crossinfection. Additionally, care has to be taken in order to ensure that they are not exposed to stressful circumstances such as low temperature and inadequate nourishment, poor ventilation, and humidity which could lead them easily susceptible to various diseases.
19.2 Diseases of Mulberry Silkworm and Their Control
19.2.1 Protozoan Diseases
The protozoa that harm silkworms are the parasitic ones from the genera Nosema, Pleistophora, and Thelohania and class Microsporidia. In addition to this, reports of Leptomonas and Trypanosoma infections in the silkworm
Bombyx mori L. have been made. However, the pebrine disease is the main protozoan illness of the silkworm. It is also known as ‘pepper disease’ because of the development of areas of black pepper after infection.
