Book Description
This text is an overall view of nematology because I believe the science should be treated as a unified discipline. The differences in the biological habits of nematodes do not justify the separation of plant nematologists and animal nematologists, since the separation is not a reflection of any difIerences inherent to nematodes. Therefore, the book is arranged with a format that in the beginning chapters illustrates the similarities and se- quence of development of morphological characters among nematodes regardless of their biological habits. The later chapters illustrate the in- tegration of the evolutionary development of the parasitie habit from related free-living forms. Nematology is probably the last major discipline to establish its inde- pendence from the parent science of zoology. This natural evolvement of nematology has occurred because of the overwhelming accumulation of sophisticated information and research that reflects the unique relation- ships of nematodes to other forms of plant and animal life as weH as their relationships in other facets of the environment.N ematodes are inverte- brate animals that, like insects, are unusual in their great numbers and varieties, their smaH size (generally microscopic), their high degree of internal organization, and their virtually ubiquitous distribution. They oc- cupy almost every ecological niehe, often causing disease of humans, other animals, and plants. These activities often result in debility, death, or in the impairment and loss of food supply with consequent loss to producers and consumers.

Book Description
This book is designed for undergraduate agricultural science students, farmers and farm extension personnel to provide a comprehensive description of plant-parasitic nematodes. It is contructed with 16 different chapters comprising of: an introduction; a brief history of plant nematology; the economic importance of nematodes; general characteristics of a plant-parasitic neamtode; general morphology of nematodes; the anatomy of nematodes; the general life cycle biology of plant-parasitic nematodes; taxonomy/systematics/classification of major plant-parasitic nematodes; classification of nematodes based on feeding habits; identification keys for major plant-parasitic nematodes; damage symptoms caused by the nematodes; interaction of nematodes with other microbial pathogens; different methods of nematode control; prominent nematode resistant crop cultivars; the concept of integrated nematode management; nematode parasites of important agricultural and horticultural crops with their management practices; and fundamental nematological techniques. The introduction covers the definition of nematodes, history of nematology, the yield loss caused by nematodes, some important animal parasitic nematodes, and beneficial nematodes including nematodes used in insect control, weed control, and biological monitoring systems. The morphology and anatomy of nematodes are simply explained with detailed diagrams. The taxonomy classification structure based on evolutionary concepts are provided with major differentiation characteristics between important groups. The life cycle of different feeding groups of plant-parasitic nematodes is illustrated with simple illustrations. Identification keys and symptoms of nematode damage are described with suitable images. Overall, nematode control techniques available in literature are summerised briefly with suitable photographs wherever needed. The nematode pests, their symptoms and specific control measures for major agro-horticultural crops like rice, wheat, cotton, pulses, groundnuts, vegetables, potatos, bananas, citrus, grapevines, spices, medicinal plants and flower crops are discussed. The final chaper of this book presents some basic nematode techniques, including nematode extraction protocols, nematode fixing, and mounting techniques. Overall, this fundamental and easy-to-understand book will be particularly useful for students in the biological and agricultural sciences, agronomists, agricultural extension workers and farmers to enable them to gain more insight and equip them with knowledge to solve problems concerning nematodes.

Book Description
The need to identify and name organisms is fundamental to any area of biological science, basic or applied. In order to study or conduct research on an organism, or to convey information on this organism to others, we must be able to attribute to it a consistent label. Attribution of an incorrect label may have dire consequences if dangerous plant parasites are wrongly identified as members of an innocuous genus. Traditional aids to nematode identification (dichotomous keys) use systematic criteria not always well adapted to practical identification. Their reliance on dichotomous principlesdoes not allow for intra-taxon variability or for missing characters. They are difficult to update and they cannot keep pace with rapidly changing classifications. As experts in everyday life, we recognize a horse or a dog wi thout referring to the taxonomic descriptions of the genera Equus or Canis and their respective species. Problems in identification arise when we are not experts in the recognition of a particular organism, or group of organisms. Then, frequently in considerable frustration, we reflect on the usefulness of having the advice of an expert in this group. Tradi tional identification aids are useful tools for the expert identifiers, and for teaching. Their use is often difficult for general practitioners in nematology, and they may lead to incorrect identification, even at the genus level.

Book Description
Plant parasitic nematodes are one of the least understood agricultural pest problems throughout the world. Science of Plant Nematology has grown rapidly is the last three decades. There is a wide gap between the vast information generated for nematode control and that, which is actually utilised. The present book ``Advances in Nematology'' provides an authoritative review account of many aspects of current interest and progress in the field of Plant Nematology that has been made in the recent past. This book includes 21 articles by eminent nematologist on different aspects of the subject. Information on application of molecular biology in nematology, nematodes as biological model, race status in plant parasitic nematodes and nematode vectors of plant diseases have been reviewed covering all major aspects. Nematode diseases on wheat, rice, tobacco, mint, barley and horticultural crops and their management, specially in context to Indian scenario have been covered. Newer approaches for the management of plant parasitic nematodes including use of VAM fungi, biocontrol agents and integrated nematode management strategies have been included to project out their use on field scale. Articles on role of nematodes in disease complexes with fungi, genetic studies on the resistance of barley, breeding for nematode resistance in forage legumes and nematode pests of economically important crops in India and their managements have been added to the value of the book. Scholars and students of Nematology, researchers and extension workers and plant pathologist will find this book very useful.
