Fruit borer: Helicoverpa armigera, Noctuidae, Lepidoptera
Biology: The adult females are light pale brownish-yellow stout moths while the male moths are pale greenish with V-shaped speck. The eggs are creamy white and sculptured type. They are laid singly. The larva shows colour variation from greenish to brown. It has dark brown grey lines on the body with lateral white lines and also has a dark band. Pupation occurs in soil, leaf, fruit, and crop debris.
Nature of damage and symptoms
• The young larvae feed on tender foliage
• Mature larvae bore into fruit through circular holes
• Larva thrust only a part of its body into fruit and eat the inner content

Gladiolus is a genus comprising around 260 species of perennial flowering plants in the iris family (Iridaceae). Commonly known as "sword lilies," the name derives from their long, blade-like leaves—gladius being the Latin word for "sword." These plants grow from underground storage organs called corms and feature tall, unbranched stems that bear vibrant, trumpet-shaped flowers arranged in a single-sided spike. Their striking appearance makes them highly valued both in gardens and as cut flowers.
Most gladiolus species are native to sub-Saharan Africa, particularly South Africa, though some are also found in Europe and Asia. The flowers come in a wide variety of colors, forms, and often display intricate patterns or ruffled edges. Each flower is bisexual and sits between green bracts, with its tepals forming a characteristic funnel-shaped corolla. Known for their bold inflorescences and extended vase life, gladiolus flowers are a popular choice in floral design and landscaping worldwide

Chrysanthemum (Chrysanthemum spp.), popularly known as “mum” or “guldaudi”, is a major commercial ornamental plant grown for cut flowers, loose flowers, and garden display. Belonging to the family Asteraceae, it is valued for its vibrant colors, diverse flower shapes, and long vase life. Chrysanthemum is attacked by several insect and mite pests, affecting both foliage and floral quality, leading to reduced aesthetic and commercial value.
Distribution: Widely distributed in India wherever chrysanthemum and sunflower are grown.
Biology: The eggs are laid singly on the upper surface of leaves, obliquely inserted into the tissue, with opercula appearing as whitish or brown dots. The incubation period for the eggs lasts about 5 to 7 weeks. Following hatching, the nymphs undergo hemimetabolous development (no true pupal stage). The nymphal period spans 2 to 3 weeks, during which the nymphs moult five times before reaching adulthood. Adult insects are approximately 4 mm long, with blackish bodies and lace-like transparent wings (Rizkawati et al., 2023).

Microbiology is the study of microorganisms or microbes. They are very small in size and hence cannot be seen with naked eyes. Microorganisms are excellent models for understanding cell function in higher organisms, including humans. Hence the science of microbiology is the foundation of all the biological sciences and microorganisms consist of bacteria, fungi, algae, protozoa and viruses. The fields according to the organisms studied are henceforth termed as:
Bacteriology - Bacteria (singular: bacterium)
Phycology (phyco, seaweed) - Algae (singular: alga)
Mycology (myco, a fungus) - Fungi (singular: fungus)
Protozoology (proto, first; zoo, animal) - Protozoa (singular: protozoan)
Virology - Viruses
Microbiology began when people learned to make lenses from glass and combine them to produce magnifications great enough to see microbes. The importance of bacteria in the lives of people, animals and the environment has been unfolded in the past 100 years. It was also believed that the incidence of the disease was due to divine reasons since man had no idea of microbes at this point of time. In the earlier days, leprosy was considered as a dangerous infectious disease and spread of the disease was attributed to direct contact with the affected persons. Hence, certain procedures were specified for
segregation of the affected persons. At this point of time various theories were also attributed to the genesis of disease. Some of the important theories are as follows:
1. Theurgical theory – Disease was attributed to the wrath of divine spirits as a punishment of individual sins.
2. Miasmatic theory – This theory was proposed by Hippocrates and further developed by his student Galen. It states that the disease was dueto the emanations from the

First discovered by Scottish surgeon sir Alexander ogston (1880) in infected tissues. He named it as staphylococcus” (Greek staphyle, bunch of grapes;
KOKKAS, berry).
Systematics
Domain : Bacteria
Phylum : Firmicutes
Class : Bacilli
Order : Bacillales
Family : Staphylococcaceae
Genus : Staphylococcus
Species : Staph. aureus
Staph. Intermedius
Staph. hyicus
Habitat and Ecology
Staphylococcus occurs worldwide in mammals although the spread of staphylococcal strains between different animal species is limited. They colonise the nasal cavity, skin and mucous membranes and can be transient in the intestinal tract. It is an opportunist type organism.

Actinobacillus species are non-motile, Gram-negative rods (0.3 to 0.5 x 0.6 to 1.4 μm) which occasionally have a coccobacillary appearance. They are non-motile, non-sporeformingand non-acid-fast. A surface slime is presentin the three major species (A. ligllieresii. A. equuli andA. suis) and may be related to the stickiness of theircolonies on agar. Surface cultures have low viabilityand die in 5-7 days. The actinobacilli ferment carbohydrates, without the production of gas, within 24 hours and most species produce urease and grow on MacConkey agar. Most species are urease and oxidase positive. The
reactions in the oxidase andcatalase tests are variable. The genus is still in a stateof flux, mainly because of the close similaritiesbetween actinobacilli and species in the genera Pasteurella and Haemophilus.
These facultative anaerobes ferment carbohydrates producing acid but not gas. Actinobacilli exhibit some host specificity and are mainly pathogens of farm animals.
Usual Habitat
Actinobacilli are commensals on mucous membranes of animals particularly in the upper respiratory tract and oral cavity. As actinobacilli cannot survive for long in the environment, carrier animals play a major role in transmission.
Colonial Appearance
• A. lignieresii: small, glistening colonies develop in 24 hours. They are usually slightly sticky (viscid) on primary isolation but lose th is characteristic on subculture. The colonies are non-haemolytic and develop to about 2 mm in diameter in 48 hours. The organism grows well on MacConkey agar, the colonies are at first pale but become pinkish as A. lignieresii is a late lactose-fermemer.
• A. equuli: some strains are haemolytic and the colonies are sticky with this feature remaining on subculture. I t is a lactose-fermenter onMacConkey agar.

Introduction
The genus Haemophilus contains small, nonmotile, nonsporing, oxidase positive, pleomorphic, gram negative bacilli that are parasitic on human beings or animals. Haemophilus means blood loving organisms.

Haemophilus species are small (less than 1 pm x 1 to 3 μm), Gram-negative rods, which often appear coccobacillary and may occasionally form short filaments. These motile organisms, which are facultative anaerobes with variable reactions in catalase and oxidase tests, do not grow on MacConkey agar. They are fastidious bacteria requiring one or both of the growth factors X (haemin) and V (nicotinamide adenine dinucleotide, NAD). Optimal growth occurs in an atmosphere of 5-10% CO2 on chocolate agar which supplies both X and V factors. Small, transparent, dewdrop-like colonies are formed by most Haemophilus species after incubation for 48 hours.

Colonies of H.somnus have a yellowish hue and some isolates are haemolytic on sheep blood agar. The main pathogens in the genus are H.somnus in cattle and sheep, H.parasuis in pigs and H.paragallinarum which is responsible for infectious coryza of chickens.

The haemophili are motile, facultative anaerobes, produce acid from glucose, reduce nitrates and are variable in the oxidase and catalase tests. They are nutritionally fastidious, will not grow on MacConkey agar and grow best on chocolate agar (supplying the X and V factors) under 5- 10 per cent CO2 at 37°C.

The growth of many of the Haemaphilus species is enhanced by 10 per cent CO2, As this is not inhibitory for any of them, CO2 should be used for routine isolation.The inoculated chocolate agar plates are incubated under 10 per cent CO2 at 35-37°C for 3-4 days, although some growth may be seen after 24 hours.

Introduction
Vibrios are Gram-negative, rigid, curved rods that are actively motile by means of a polar flagellum. The name ‘Vibrio’ is derived from the characteristic vibratory motility (from vibrare, meaning to vibrate). They are asporogenous and noncapsulated. Vibrios are present in marine environments and surface waters worldwide. The most important member of the genus is Vibrio cholerae, the causative agent of cholera. It was first isolated by Koch (1883) from cholera patients in Egypt, though it has been observed earlier by Pacini (1884) and others.
Natural Habitat
Vibrio spp. can be present in both freshwater and seawater as well as in the alimentary tracts of animals and man. At least five Vibrio spp. are human pathogens including V. cholerae, the cholera bacillus, and V.parahaemolyticus which causes food poisoning. Only V. metschnikovii is associated with disease in domestic animals. It causes a cholera-like disease in chickens and other birds but its geographical distribution is very limited. V. anguillarum causes infections in many species of fish especially in salt or brackish water. It causes high mortality in salt water eels.
Vibrio Cholerae
Morphology
The cholera vibrio is a short, curved, cylindrical rod, about 1.5 × 0.2-0.4 mm in size, with rounded or slightly pointed ends. The cell is typically comma shaped (hence the old name V comma) but the curvature is often lost on subculture. S-shaped or spiral form may be seen due to two or more cells lying end to end. Pleomorphism is frequent in old cultures. In stained films of mucus flakes from acute cholera cases, the vibrios are seen arranged in parallel rows,

Bacteroides spp are non-spore forming gram-negative bacilli that are part of the human resident flora. Microbiologically, they are distinguished from other genera by growth in 20% bile. At present, the Bacteroides fragilis group consists of ten species: B. fragilis (the most frequent isolate), B. distasonis, B. thetaiotaomicron, B. vulgatus, B. ovatus, B. eggerrthii, B. merdae, B. stercoris, B. uniformis, and B. caccae. Since 1990, many organisms previously designated as Bacteroides have been reclassified (see chapter on Anaerobes other than Bacteroides). Bacteroides, the predominant genus in the human
intestine, are important in numerous metabolic activities and may provide some level of protection from invasive pathogens. All 10 species are usually isolated from the colon, although infections caused by or associated with them can include virtually any organ.
Characteristics
The gram-negative Bacteroides spp. or closely related genera are capsulated obligatory anaerobic bacilli that are non-spore forming, pale-staining, and some are motile by peritrichous flagella, while other taxa are non-motile. Bacteroides, Parabacteroides, Odoribacter are generally bile resistant, distinguished from genera which are bile sensitive. They are normally commensal, found in the
intestinal tract of humans (mouth, colon, urogenital tract) and other animals. Many cultures of Bacteroides strains display brown to black pigmentation on blood agar media caused by esculin hydrolysis.
Morphology
In general, all strains were stained poorly with safranin, but well with dilute carbolfuchsin. Motility was not observed in any strains. The morphology of Bacteroides fragilis in fresh cultures and in pus is not
especially characteristic. In this form, the bacillus measures 0.5 by 2.0 to 2.5 micra. Older cultures tend to develop larger forms (0.6 to 0.8 by 2.0 to 9.0 micra) but even in this state the organism cannot be distinguished from aerobic Gram-negative bacilli, by its morphology.

The mycoplasmas are microorganisms in the class Mollicutes. Of the nine genera in this class, five contain species of veterinary interest. The genus Mycoplasma, in which there are about 100 species, contains most of the animal pathogens. The first mycoplasma identified in 1890 was Mycoplasma mycoides subspecies mycoides, the cause of contagious bovine pleuropneumonia. Similar types of mycoplasmas which were subsequently identified were called pleuropneumonia- like organisms (PPLO).
Mycoplasmas, the smallest prokaryotic cells capable of self-replication, are pleomorphic organisms ranging from spherical (0.3 to 0.9 pm in diameter) to filamentous (up to 1.0 μm long). Because they cannot synthesize peptidoglycan or its precursors, they do not possess rigid cell walls but have flexible, triplelayged outer membranes.
Their flexibility allows them to pass through bacterial membrane filters of pore size 0.22 to 0.45 μm. Mycoplasmas are susceptible to desiccation, heat, detergents and disinfectants. However, they are resistant to antibiotics such as penicillin which interfere with the synthesis of bacterial cell walls. Based on 5s rRNA sequence analyses, the mycoplasmas have been shown to be linked phylogenetically to Gram-positive bacteria such as Clostridium species which have low guanine-cytosine content in their DNA. They require enriched media for growth, characteristically forming umbonate micro-colonies
when illuminated obliquely and microcolonies with a ‘fried egg’ dppearance in transmitted light. The dense central zone is due to extension of the microcolony into the agar. Mycoplasmas, which have relatively small genomes (approximately 800 genes) are fastidious in their growth requirements.
Most mycoplasmas are facultative anaerobes and some grow optimally in an atmosphere of 5 to 10% CO2. Nonpathogenic anaerobic mycoplasmas are found in the rumens of sheep and cattle. The genera Mycoplasma and Ureaplasma contain animal pathogens.

Introduction
Q fever is a zoonotic bacterial infection caused by Coxiella burnetii, an obligate intracellular parasite, classified within the family Rickettsiaccae. Q fever (Q for “query”) was first used in 1937 to describe a mysterious febrile illness of packing house workers in Brisbane, Australia. The causative agent was isolated from infected workers and later was identified as Rickettsiae. Almost simultaneously the same organism was identified wood tick collected in Montana. Cox, an American, and Burnet, an Australian, where honored for their early work with this organism, hence the name “Coxiella burnetii”.
Host and Susceptibility
Coxiella burnetii is a well-established infectious agent that has reached a state of balanced pathogenicity in a plethora of host. Human are unnatural and usually dead-end-host. The microorganism generally maintained in a less pathogenic form in separate cycle existing independently among wild mammals and their haematophagus arthropods, principally tick and in domestic animals.
Morphology
It is an intracellular organism which is a polymorphic bacillus (0.2-0.4mm width, 0.4-1.0 mm length), which has a cell membrane, like Gram negative bacteria. However, it stains poorly with pigmented Gram stain, but gimenez staining is traditionally used to stain the Coxiella burnetii pathogen from pathological materials and crop. Coxiella burnetii has several distinctive characteristics, including a sporulationlike
process that protects the organism against the external environment, where it can survive for long periods. In mammals, the usual host cell of C. burnetii is the macrophage, which is unable to kill the bacterium. The other an important characteristic of C. burnetii is its antigenic variations, those called phase variation. This antigenic shift can be measured and is valuable for differentiating acute from chronic Q fever. Thus, it displays two antigenic phases those are phase-I and phase- II that are liable to the Lipopolysaccharide (LPS) of the membrane.

Bacteria from the genus Anaplasma belong to the Procaryota kingdom, the family Anaplasmataceae. Anaplasma belong to obligate intracellular microorganisms, Gram-negative bacteria, living in the blood cells of mammals. Vertebrates can be their reservoir, i.e. an environment where the pathogen can live and proliferate for many years. However, in many cases bacteria from the genus Anaplasma cause diseases in domestic animals and people.
Taxonomical Position of Bacteria from the Genus Anaplasma
The genera Anaplasma, Ehrlichia, Neorickettsia and Wolbachia include obligate intracellular bacteria, parasitizing in the vacuoles of cells in eukarytic hosts. Animal pathogens were attributed to the genus Anaplasma, such as A. centrale, A. marginale, A. platys, A. ovis and A. bovis, and also the aetiological factor of human anaplasmosis, A. phagocytophilum.
Anaplasma marginale
A. marginale are obligate intracellular bacteria parasitizing in erythrocytes of higher vertebrates, mostly ruminants.
Anaplasma Centrale
A. centrale is a parasite in the erythrocytes of ruminants, mainly cattle. As opposed to A. marginale, it creates concentrations in the central part of the cell. A. centrale is less pathogenic to cattle than A. marginale but, most importantly, occasionally gives resistance against the latter. Hence it is used for the preparation of live vaccine strains, assuring immunological protection against bovine anaplasmosis.
Anaplasma Bovis
A. bovis is a bacterium detected mainly in cattle, but also observed in small mammals which are probably a reservoir of this bacterium. It occurs in monocytes, and the disease it causes is called monocytic anaplasmosis. The symptoms of the disease are most visible in calves, but also in adult animals; symptoms include weakening of the body, marked reduction in weight, elevated temperature, enlargement of prescapular lymph nodes, paling of the mucous membranes, and in many cases an elevated amount of secreted mucus.

Organisms in the order Rickettsiales form a diverse group of small (0.3 to 0.5 x 0.8 to 2.0 pm), non-motile, pleomorphic Gram-negative bacteria which replicate only in host cells. They can be cultured in the yolk sac of embryonated eggs or in selected tissue culture cell lines. Because they stain poorly with aniline dyes, these organisms should be stained by Romanowsky methods such as Giemsa or Leishman. In addition to host-cell dependence and poor affinity for basic dyes, a requirement for an invertebrate vector distinguishes them from conventional bacteria and the Chlamydiales.
Epidemiology
Animal hosts and arthropod vectors are the reservoirs for most rickettsiae. A number of rickettsia1 organisms, including Ehrlichia canis, Anaplasma marginale and Haemobartonella felis produce latent infections. In arthropods, rickettsiae replicate in the epithelial cells of the gut before spreading to other organs, including the salivary glands and ovaries where further replication may occur.
Organisms are transmitted when the arthropod feeds on the animal host. Some organisms such as Rickettsia rickettsii are maintained in a tick population by transovarial transmission. Trans-stadial but not transovarial transmission of E. canis and E. phagocytophila occurs in ticks. With the exception of Coxiella burnetii, which produces endospore-like forms and can remain viable in dust for up to 50 days, most rickettsiae are labile outside host cells. Aerosol transmission of C.burnetii commonly occurs in domestic animals and humans. In addition, a silent cycle involving ticks and small wild mammals may constitute a possible source of infection for some domestic species.
Pathogenesis and Pathogenicity
Many Rickettsia species including the causal agents of typhus (R. prowuzekii), murine typhus (R. typhi) and scrub typhus (R. tsutsugamushi) are primarily human pathogens. Rocky Mountain spotted fever, caused by Rickettsia rickettsii, which is a common rickettsia1 disease of humans, also affects dogs.

Chlamydiae are obligate intracellular bacteria with an unusual developmental cycle during which unique infectious forms are produced. They replicate within cytoplasmic vacuoles in host cells. On account of their apparent inability to generate ATP, with resultant dependence on host cell metabolism, they have been termed ‘energy parasites’.
The family Chlamydiaceae belongs to the order Chlamydiales. Currently two genera, Chlamydia and Chlamydophila, and nine species are described. Formerly a single genus and four species, Chlamydia trachomatis, C. psittaci, C. pneumoniae and C. pecorum, were recognised. This classification was based on phenotypic characteristics such as host preference, inclusion morphology, iodine staining for the presence of glycogen, and sulphonamide susceptibility. However, recent nucleic acid sequencing studies of the 16s and 23s rRNA genes confirm two distinct lineages.
In the developmental cycle of chlamydiae, infectious and reproductive forms are morphologically distinct. Infectious extracellular forms, called elementary bodies (EBs) are small (200 to 300 nm), metabolically inert and osmotically stable. Each EB is surrounded by a conventional bacterial cytoplasmic membrane, a periplasmic space and an outer envelope containing lipopolysaccharide.
The periplasmic space does not contain a detectable peptidoglycan layer and the EB relies on disulphide cross-linked envelope proteins for osmotic stability. Elementary bodies enter host cells by receptor-mediated endocytosis. Acidification of the endosome and fusion with lysosomes are prevented by mechanisms which are not fully understood. A process of structural reorganization within the pathogen, of several hours duration, results in the conversion of an EB into a reticulate body (RB). The RB, about 1 μm in diameter, is metabolically active, osmotically fragile and replicates by binary fission within the endosome. The endosome and its contents, when stained, is called an inclusion. When a number of inclusions containing RBs of C.trachomatis are formed in an infected cell, fusion of these structures may
occur.

The Government of India, during 1980s, recognized the necessity to improve the latex yield productivity in the traditional rubber growing regions and also expand these plantations to non-traditional regions to meet the ever increasing demands of natural rubber in India (Sethuraj et al., 1989). Agrometeorological studies were initiated during early 1986 with the appointment of a Scientist (Agrometeorology). To begin with, scientific issues were identified as: (a) delineate the potential non-traditional regions for expansion of rubberplantations, (b) estimate the impact of climatic conditions, especially abiotic  stress conditions on productivity, (c) quantify influence of meteorological factors on the physiological responses towards plant growth and yield attributes, (d) estimate the irrigation requirements to mitigate the drought conditions, and (e) develop weather based predictive models for `Abnormal leaf fall’ disease of rubber plantations. An attempt is made to present synthesis of accomplishments during 1986 to 1992 period of my association with the Rubber Research Institute of India (RRII), Kottayam.

achieving perfect alignment using smartphone applications.
Understanding Audio Synchronization in Mobile Video Editing
Audio synchronization, or “lip-syncing,” is particularly vital in videos where
dialogue, music, or sound effects are synchronized with visual cues. Accurate synchronization can help convey emotions, emphasize actions, and create an immersive experience. On smartphones, achieving perfect synchronization requires both intuitive tools and practical techniques to account for various factors, such as audio drift, frame rates, and video quality.
Smartphone applications for video editing typically support audio synchronization through visual audio waveform displays, alignment tools, and timing adjustments. These features empower users to manually or automatically adjust and align audio with visual footage.

Introduction
Video and audio editing encompass two primary modes: online and offline editing, each critical for producing high-quality, synchronized media content. Online editing refers to real-time editing with high-resolution files, typically as a final step in the post-production workflow. Offline editing involves working with lower-resolution copies or proxies of footage for easier manipulation and organization, saving time and computational resources. Both techniques hold unique advantages and can be integrated depending on project requirements, available resources, and editing goals.
Section 1: Understanding Offline Editing
1.1 Overview of Offline Editing
Offline editing is the preliminary editing stage where editors work with lower-resolution copies of the original footage to perform initial edits. This approach optimizes efficiency, as low-resolution files consume less storage and processing power. Common in projects with extensive footage, such as feature films, documentaries, and complex multimedia presentations, offline editing allows editors to focus on the structure, sequencing, and timing of content without concerns over resource demands.

As video editing continues to evolve, so do the techniques and software that enable editors to create polished, captivating visuals. Advanced editing techniques like precision cutting, mixing, and using sophisticated software tools allow editors to enhance storytelling, manipulate pace, and shape the emotional experience of their audience. This chapter dives into these advanced techniques, exploring how each tool and method contributes to a compelling final product.
1. The Art of Cutting: Techniques for Seamless Storytelling
Cutting is a fundamental editing skill that determines the pacing, continuity, and flow of a video. Advanced cutting techniques, such as L-cuts, J-cuts, and match cuts, serve as the foundation for creating dynamic narratives.
• Types of Cuts
• L-Cut and J-Cut: L-cuts and J-cuts are used to transition between audio and video in ways that flow more naturally and create smoother  continuity between scenes. These are essential techniques for dialogue-driven scenes or scenes that require seamless transitions between different locations or times.

Abstract
Aquatic weeds, such as duckweed, present a dual challenge and opportunity within aquatic ecosystems and the poultry feed industry. These fast-growing plants, often deemed nuisances due to their potential to disrupt ecosystems, offer significant potential as alternative feed sources. Duckweed, a floating aquatic plant, is particularly noteworthy due to its high protein content, rapid growth rate, and nutrient recycling capabilities. In freshwater systems, excessive growth of aquatic weeds can lead to decreased ecosystem productivity, hypoxia, and anoxia, making effective management crucial. However, duckweed’s ability to thrive in nutrient-rich conditions and its high nutritional value, including substantial protein and essential vitamins, position it as a valuable feed ingredient for poultry. The Indian poultry sector, growing at an annual rate of 8-10%, faces challenges such as rising feed costs and limited availability of conventional feed ingredients. Integrating duckweed into poultry diets can provide a cost-effective, sustainable alternative that reduces reliance on traditional feed sources and supports ecosystem management. This approach not only addresses feed shortages but also contributes to environmental sustainability by recycling nutrients and mitigating pollution. Despite its potential, challenges such as lack of standardized regulations and market acceptance remain. Continued research, policy support, and market promotion are essential to harness the full benefits of aquatic weeds.

Introduction
Plants have been used for ages as animal and human health cures. Ethnoveterinary medicines, a phrase that primarily refers to folk skills, beliefs, knowledge, practices, and procedures related to animal health and the treatment of various disorders in rural regions, have acknowledged the ability of plants to combat a variety of diseases. The World Health Organisation (WHO) defines traditional medicine, also referred to as herbal medicine, as “When it comes to maintaining health and preventing, diagnosing, improving, or treating physical and mental illnesses, the entirety of the knowledge, abilities, and practices derived from indigenous theories, beliefs, and experiences whether or not they can be explained as illness”. Approximately 25% of contemporary medications are derived from plants that were once used in traditional medicine. The use of traditional medicine and its confirmation could result in the creation and discovery of more novel medications.

Introduction
Helminths are a group of internal parasites of animals and human beings that usually infest gastrointestinal tract that feed from the host which provides protection to the parasite. The infestation cause loss of blood and nutrients from the host, making it weak, and vulnerable to other infections. There can be injury to other organs due to the migration of different stages of the parasite, formation of cysts or secretion of toxins that can cause damage.
The heminths belong to two phyla including nemathelminthes which are round worms and Platyhelminthes that has flukes, and tapeworms. Nematodes are round worms who have a resistant cuticle and most of them have separate sexes with direct or indirect life cycle. The major nematodes include Ascarids, Strongyles, strongyloides, Trichostrongyles, Filarids, Trichuris etc. Tape worms have a flat body with a head or scolex, neck and strobili having proglottids. They are hermaphrodites and the proglottids contain reproductive organs. They require more than one host for completion of life cycle. The flukes are ususally leaf like , unsegmented and have suckers that help them to attach to the internal organs of the host. They also have a life cycle in more than one host.

The kidney plays a role in controlling the volume of different bodily fluids, fluid osmolality, acid-base balance, toxin elimination, and different electrolyte concentrations. The glomerulus filters one-fifth of the volume of blood that enters the kidneys. Among the compounds that are reabsorbed include amino acids, salt, bicarbonate, glucose, and solute-free water. Among the chemicals that are released are ammonium, potassium, hydrogen, and uric acid. The kidneys maintain homeostasis, eliminate metabolic waste products like uric acid, urea, creatinine and ammonia, regulate extracellular fluid volume, blood pressure (via the rennin-angiotensin system) and controlling systemic pH (via regulation of H+ and HCO3- concentration).
Among various kidney diseases, especially chronic kidney disease (CKD) is a slow loss of kidney function in which, kidney dysfunction is present for more than three months. There are six progressive stages of CKD i.e. stages 1, 2, 3a, 3b, 4 and 5. The stages are based on the results of glomerular filtration rate (GFR) test (1). In stage 1 there is mild kidney damage, while in stage 5 kidneys lost their working capacity. Chronic kidney disease (CKD) is a worldwide health issue that is becoming more prevalent in both developed and developing nations. It typically affects adults. .

Nervous system Disorders in Domestic Animals
Nervous system disorders in domestic animals encompass a range of conditions that affect the brain, peripheral nerves, and spinal cord. These disorders can result in a variety of clinical signs, depending on the area of the nervous system involved. Infectious disorders like rabies, canine distemper, toxoplasmosis, listeriosis. Congenital and developmental disorders like hydrocephalus, cerebellar hypoplasia and chiari-like malformation can cause these disorders. Traumatic and degenerative disorders like Intervertebral Disc Disease. Degenerative myelopathy, metabolic and toxic disorders like hepatic encephalopathy, hypocalcemia, lead poisoning, organophosphate toxicity, autoimmune and inflammatory disorders like meningitis and meningoencephalitis may also lead to nervous system disorders. Some tumours associated with nervous system like meningiomas and peripheral nerve sheathtumours also cause nervous system disorders.  

Abstract
Aquaculture is the fastest-growing food production sector globally, with finfish and crustaceans playing a significant role in meeting the growing demand for animal protein. However, aquaculture’s reliance on marine capture fisheries for essential feed ingredients, such as fishmeal and fish oil, presents significant sustainability challenges. The Fish In: Fish Out (FIFO) ratio, which estimates the quantity of wild-caught fish used to generate one unit of reared fish, has become a key metric in assessing the sustainability of aquaculture. A high FIFO ratio indicates greater dependence on wild fish stocks, contributing to overfishing and ecosystem degradation. This chapter explores the FIFO ratio, its role in promoting sustainable aquaculture, and innovations to reduce its environmental impact. Over the years, the global average FIFO ratio has improved, reflecting advances in feed efficiency and the incorporation of alternative ingredients such as plant-based proteins, insect meals, and by-products from fish processing. However, challenges remain in these alternatives’ availability, cost, and nutritional performance. Case studies, including salmon rearing in Scotland and shrimp farming in Thailand, demonstrate the potential of alternative feed ingredients in lowering FIFO ratios and enhancing sustainability. This chapter also addresses the limitations of the FIFO ratio as a singular sustainability metric, calling for a more holistic approach to evaluating aquaculture’s environmental and economic impacts. Ultimately, achieving sustainable FIFO ratios will require
continued innovation, improved feed formulations, and global collaboration to ensure aquaculture’s role in providing a sustainable source of protein for the growing global population.

Abstract
Coastal wetlands, including mangroves, salt marshes, and seagrass meadows, play a critical role in regulating the global climate by sequestering carbon. These ecosystems act as vital carbon sinks, efficiently absorbing and storing carbon in their biomass and soils. Despite covering only 2-3% of the planet’s surface, coastal wetlands are believed to store more than half of the world’s carbon in the top meter of soil, helping to mitigate climate change. The unique hydrological and biological characteristics of these ecosystems, such as their ability to slow the decomposition of organic matter and facilitate sediment burial, are crucial to their carbon storage capacity.
In addition to their role in carbon sequestration, coastal wetlands provide essential ecological services, including supporting biodiversity, preventing erosion, and protecting against storm surges. However, they face significant threats from pollution, climate change, human activity, and hydrological alterations, which could jeopardize their ability to store carbon. Preserving and restoring coastal wetlands is essential for maintaining their carbon sequestration capacity and strengthening climate resilience. Effective wetland conservation efforts, including sustainable land-use practices and restoration techniques like sediment augmentation, are essential to ensure these vital ecosystems continue to contribute to climate regulation.

Abstract
Phytotechnology, particularly through the utilization of plankton such as phytoplankton, offers innovative solutions to pressing environmental challenges, including pollution control, resource scarcity, and climate change. These microorganisms excel in carbon sequestration, pollutant removal, nutrient recycling, and resource recovery. They can address issues like eutrophication, heavy metal contamination, and oil spill degradation, while also contributing to biofuel production, agricultural enhancement, and the development of high-value products. However, large-scale implementation faces several challenges, including energy-intensive processes, high costs, resource competition, and environmental safety concerns, particularly the risks associated with genetically modified organisms. Progress in genetic engineering, photo bioreactor design, and integration with wastewater treatment systems, along with collaboration among scientists, policymakers, and industries, is essential for overcoming these challenges. Strategic investments have the potential to fully harness the capabilities of plankton as sustainable agents for environmental restoration and resource recovery.

Abstract
Infectious diseases pose significant threats to global aquaculture, causing substantial economic losses exacerbated by intensive farming practices. RNA viruses, including birnavirus, nodavirus, rhabdovirus, and others, infect both wild and cultured fish, leading to severe mortalities. This study focused on detecting two RNA viruses, Infectious Hematopoietic Necrosis Virus (IHNV) and Spring Viremia of Carp Virus (SVCV), using the TRIZOL reagent method. Fish samples, including Tilapia, Mrigal, Catla, and Minor carp, were observed for clinical symptoms and dissected to collect organs like kidney and spleen. RNA extraction was performed using TRIZOL, followed by cDNA synthesis and PCR amplification targeting specific viral genes. Gel electrophoresis confirmed the absence of IHNV and SVCV in all samples tested. This comprehensive methodology ensures efficient surveillance and early detection of viral infections in aquaculture, thereby enhancing disease management strategies and economic sustainability. The findings indicate a current absence of IHNV and SVCV in the studied fish populations, emphasizing the importance of ongoing monitoring to safeguard aquatic health.

Impact assessment approaches
Impact assessment approaches can be classified into four broad categories i.e. quantitative, qualitative, participatory and mixed methods.
i. Quantitative impact assessment approaches
• It focuses on assessing the degree and extent of the impacts quantitatively.
• Some degree of quantification may be necessary in all impact assessments, in order to evaluate the success of the Intervention and the extent of any adverse effects.
• Largely depends on micro-economic approaches following econometric models
• Involving baseline studies: The precise identification of baseline conditions, definition of objectives, target setting, rigorous performance evaluation and outcome measurement
• Costly and limited scope: Limited in the types of impacts which can be accurately measured and may pose difficulties for inference of cause and effect.

Agricultural extension services are critical for the dissemination of knowledge, technologies and innovations among farmers, leading to improved agricultural productivity, sustainability and livelihoods. Different countries have adopted varied approaches to extension policies, reflecting their unique socioeconomic, political and agro-ecological contexts. Here’s an overview of
extension policies in different regions:
1. United States: In the United States, the Cooperative Extension Service, established under the Smith-Lever Act of 1914, is a nationwide, publicly funded network that connects land-grant universities with local communities. It provides educational programs, resources and advisory services to farmers, ranchers and rural residents. The U.S. model emphasizes partnerships between federal, state and local governments, as well as with the private sector, to deliver extension services.
2. India: India has a diverse and decentralized extension system comprising public, private and Non-Governmental Organizations (NGOs). The National Mission on Agricultural Extension and Technology (NMAET) is the central government’s flagship program that focuses on agricultural extension, including farmer capacity building, technology disseminationand knowledge management. Despite this, challenges such as inadequate funding, limited reach and poor coordination across agencies persist, leading to calls for reform and more innovative approaches like Information and Communication Technology (ICT) integration.

7.1 Introduction
The three factors used to categorise silkworm races are: (1) origin, (2) voltinism and (3) moulting. In addition, they are categorised according to their shape and colour. For more than 2,000 years, people have tamed and raised the silkworm Bombyx mori. It is a monophagous insect that exclusively consumes the leaves of mulberries. As a result, mulberry silk is typically meant when the word “silk” is used.
7.2 Classification Based on the Place of Origin
(a) Indian Races: Native to South East Asia and India; these races are indigenous. They have a longer larval stage and can withstand high humidity and temperatures. The larvae and cocoon are modest in size. The cocoon is often spindle-shaped and coloured in shades of green, yellow, or golden yellow. With a lower shell percentage, the cocoon shell is thin and most of them are multivoltine.
(b) Japanese Races: Japan’s indigenous races comprise this group. The larvae are strong. The cocoon resembles a peanut. The majority of cocoons are white, while some are yellow in hue. There are more double cocoons in the ratio. The silk strand is thick and short and of poor quality and are bivoltine or univoltine.

India’s rural economy plays a vital role in the overall development of the country, with a significant portion of the population dependent on agriculture and allied sectors for their livelihood. Despite the structural changes in
the Indian economy over the past decades, agriculture continues to be the primary source of income for a majority of rural households. However, the income levels of farmers and rural people vary widely due to factors such as landholding size, access to resources, market linkages, climatic conditions, education, and government support systems.
The average monthly income of agricultural households in India has been a matter of concern and active policy intervention. According to reports from the National Sample Survey Office (NSSO) and other government bodies, many small and marginal farmers earn less than what is required for a sustainable  livelihood. This income typically comes from multiple sources, including crop production, livestock rearing, wages, and non-farm activities. Yet, the increasing input costs, fluctuating market prices, and the vulnerability to climatic shocks make farming a risky and often unremunerative occupation. To address these challenges, various initiatives have been undertaken by the Government of India, such as the Doubling Farmers’ Income (DFI) strategy, minimum support prices (MSP), crop insurance schemes like PMFBY (Pradhan Mantri Fasal Bima Yojana), rural employment guarantee schemes like MGNREGS, and efforts to promote farmer producer organizations (FPOs).

Livelihood refers to the means and capabilities by which individuals and households secure the necessities of life such as food, shelter, clothing, education, and healthcare. It encompasses not just the income-generating
activities people undertake, but also the assets, skills, knowledge, and social networks they use to sustain and improve their living conditions. The concept of livelihood is broader than employment or income; it includes access to natural, financial, social, human, and physical capital that enable people to build a decent standard of living.
A widely accepted definition by the Sustainable Livelihood Framework (developed by the UK’s Department for International Development) states that a livelihood comprises “the capabilities, assets (including both material and
social resources), and activities required for a means of living.” A livelihood is considered sustainable when it can cope with and recover from stresses and shocks, maintain or enhance its capabilities and assets, and provide sustainable livelihood opportunities for the next generation. In India, livelihood patterns differ significantly between urban and rural areas due to differences in economic structures, resource availability, access to services, and lifestyle choices.

Studying livelihood systems requires a multidimensional approach, as livelihoods are shaped by a variety of social, economic, environmental, and institutional factors. To understand how individuals and communities sustain
their lives, researchers and policymakers use a range of indicators that help analyze both the opportunities available and the vulnerabilities faced by people. These indicators provide insights into the resources people use, the strategies they adopt, and the outcomes they achieve in their pursuit of a secure and dignified living. One of the foundational frameworks for analyzing livelihoods is the Sustainable Livelihoods Framework (SLF), which identifies five core categories of capital or assets: human capital, natural capital, financial capital, physical capital, and social capital. Indicators related to each of these asset types are commonly used in livelihood studies.
Apart from these core assets, livelihood outcome indicators are also important. These include levels of food security, poverty status, employment stability, quality of life, savings and investment behavior, and ability to withstand shocks. These outcomes provide a picture of whether the livelihood strategies adopted are sustainable and equitable. Institutional and policy indicators are equally significant. These include access to government schemes, land rights, legal entitlements, effectiveness of rural development programs, and availability of extension services. The role of markets, financial institutions, and governance structures must also be considered when evaluating livelihood systems. In the context of vulnerability, indicators like frequency of crop failure, income variability, health risks, and exposure to natural disasters are used to assess how secure or fragile a livelihood is. Coping strategies, such as migration, asset liquidation, or diversification of income sources, are also analyzed.

Types of Traditional and Modern Farming Systems
India, with its diverse agro-climatic conditions, has witnessed the coexistence of both traditional and modern farming systems. These systems reflect the evolution of agricultural practices—from indigenous knowledge and
subsistence farming to technology-driven, market-oriented approaches. A. Traditional Farming Systems Traditional farming systems are based on indigenous knowledge, ecological balance, and subsistence needs. These systems are often practiced by tribal, marginal, and small-scale farmers and are well-adapted to local environments.
Types of Traditional Farming Systems
1. Subsistence Farming
Subsistence farming is a traditional farming system in which a farmer grows crops and/or rears livestock mainly to meet the needs of their own family, with little or no surplus for sale in the market. It is generally practiced on small landholdings, using simple tools, indigenous seeds, and family labor.
• Focus: Meeting the food needs of the family.
• Crops: Millets, pulses, vegetables.
• Tools: Manual or animal-drawn implements.

Small, medium, and large enterprises (SMEs and LEs) play a vital role in any economy by providing goods, services, and employment opportunities. Each category has unique characteristics, challenges, and significance within the economy. Value chains are integral to understanding how these enterprises operate and compete in the market. Enterprises in agriculture and allied sectors are classified based on investment, turnover, and scale of operation. These enterprises form the backbone of agri-based value chains, providing crucial support in production, processing, storage, marketing, and distribution.
Here’s an overview of SMEs, LEs, and their value chains:
Small Enterprises
Definition
• Typically have fewer than 50 employees.
• Annual revenue varies by country but is generally less than $10 million.
Characteristics
• Often family-owned or local businesses.
• Serve niche markets and local communities.
• Limited resources for marketing, technology, and personnel.
• Higher flexibility and capacity for innovation due to fewer bureaucratic hurdles.

The integration of various farming enterprises—such as crops, livestock, poultry, fishery, horticulture, agroforestry, and others—plays a vital role in strengthening rural livelihoods. However, successful integration depends on
a variety of interrelated factors. The first and foremost is the agro-climatic condition of the area, which includes soil type, rainfall pattern, temperature, humidity, and elevation. These factors determine the suitability of different
enterprises and their possible combinations. For example, fish farming is more viable in water-abundant regions, while goat farming is more appropriate in dry or hilly regions. Landholding size and its layout also greatly influence
enterprise integration. Farmers with larger and well-demarcated plots have more flexibility to integrate different components such as ponds for fish, sheds for livestock, and space for crops or horticulture. On the other hand, marginal and small farmers may find it challenging to accommodate multiple enterprises without careful planning. Similarly, water availability is a key determinant, especially for integrating enterprises like fishery, dairy, and horticulture, which require regular and ample water supply. The presence of water harvesting structures or access to irrigation facilities enhances integration potential.
