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
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
Nickle (Beltsille Agricultural Research Center of the USDA) has engaged 29 internationally known experts to replace the classic work of I.N. Filipjev (1934) and its translated revision (Schuurmans Stekhoven, Jr., 1941) with a modern work taking note of 188 additional genera, and 4,650 more species.

Book Description
Plant-parasitic and free-living nematodes are increasingly important in relation to food security, quarantine measures, ecology (including pollution studies), and research on host-parasite interactions. Being mostly microscopic, nematodes are challenging organisms for research. Techniques for Work with Plant and Soil Nematodes introduces the basic techniques for laboratory and field work with plant-parasitic and free-living soil-dwelling nematodes. Written by an international team of experts, this book is extensively illustrated, and addresses both fundamental traditional techniques and new methodologies. The book covers areas that have become more widespread over recent years, such as techniques used in diagnostic laboratories, including computerized methods to count and identify nematodes. Information on physiological assays, electron microscopy techniques and basic information on current molecular methodologies and their various applications is also included.

Book Description
Plant parasitic nematodes are major pests of agricultural crops and cause huge monetary losses. There is a very high risk of spread of plant-parasitic nematodes from one country to another, with the movement of plants and planting materials such as seeds, bulbs, corms, suckers, tubers, rhizomes, rooted plants, nursery stock and cut flowers. In view of the large quantities and the wide variety of materials being imported and exported, it is important to assess the status of invasive nematodes and their quarantine importance in relation to agricultural trade. This book contains information on around 100 invasive nematodes and their potential threat in different countries. Each nematode entry includes information on authentic identification, geographical distribution, risk of introduction, host ranges, symptoms, biology, ecology, planting material liable to carry the nematode(s), nematode vectors, chance of establishment, likely impact, and phytosanitary measures. There are detailed accounts of diagnosis procedures including sampling, isolation, detection and identification of nematodes based on morphological and molecular characters. The book offers a global perspective on invasive plant-parasitic nematodes and useful for practitioners, professionals, scientists, researchers, students, and government officials working in plant quarantine and biosecurity.

Book Description
Formerly titled Plant-Parasitic Nematodes: A Pictorial Key to Genera, this volume has been the standard work on plant disease around the globe. Now in its fifth edition, it remains the fundamental reference for students as well as for diagnosticians—a usable, comprehensive key to plant-parasitic nematodes and the only guide to feature both photographs and drawings. Accompanied by full-page plates, the book offers descriptions of 68 genera, including most that have one or more species known to be plant parasites. The bibliography of approximately 2,500 entries on the taxonomy and morphology of nematode genera is one of the fullest on this subject. For the present edition, the authors have made revisions throughout and have added references to more than two hundred genera not previously included. An updated taxonomy, glossary, and an index are also provided. William F. Mai is Liberty Hyde Bailey Emeritus professor, Peter G. Mullin is Coordinator of Laboratory Instruction, and Howard H. Lyon is Biological Photographer (retired) in the Department of Plant Pathology, Cornell University.
