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.

The volume deals with morphology, taxonomy and systematics of entomopathogenic nematodes (EPN) in the families Steinernematidae and Heterorhabditidae and bacteria associated with these nematodes. In the first part, history, taxonomic status, family and genus definitions of EPN are mentioned. In the second part, all useful aspects of morphology and methodology of EPN are mentioned with illustrations and SEM photographs and instructions on how to make the measurements, and how to use them in taxonomic work. A polychotomous key with SEM photographs and illustrations is provided. In the third part, full descriptions of all species are presented with latest information about each species. In the fourth part, molecular and phylogenetic methods for working with EPN are presented, including the latest information and instructions on how to use molecular data in taxonomic work. In the last part, bacteria associated with this group of nematodes are discussed in the context of the latest information about methodology, biology and taxon.

Nematology being an established discipline covers a wide range of area ranging from basic aspect to the advanced and applied aspects involving recent advances in molecular techniques. This book discusses the following topics: the role of nematodes in our life (in agriculture, ecosystem functioning, experimental biology, ecological studies, pest management programs, or biocontrol), identification of GRSPs in nematode genomes, novel way for the diagnosis of pathogenic nematodes involving various recent molecular techniques, other methodologies for successful control of termites, evolution of plant-parasitic nematodes, viability of adult filarial nematode parasites, the impact of plant-parasitic nematodes on crops, and harnessing useful rhizosphere microorganisms for nematode control. The book also encompasses on classical study, molecular study, bioinformatics in nematology, biodiversity analysis, and culturing of nematodes in laboratory condition.

In Advances in Entomopathogenic Nematode Taxonomy and Phylogenythe numerous species of Steinernemaand Heterorhabditisdescribed since the previous volume, published in 2007, are evaluated and discussed. Valid species proposed from 2007-2015 are covered in detail, each taxon having an illustrated diagnostic description and additional data on molecular characterisation, distribution and biology, etc. An addendum gives brief details of species proposed during 2016. An overview of the taxonomy of the two families provides an up-to-date list of species for both genera, including new synonyms and detailed commentary on specific status where appropriate. Tabular keys to all valid species of Steinernemaand Heterorhabditisassist in diagnostics. A chapter on phylogeny and phylogeography completes the book.

Plant parasitic nematodes are costly burdens of crop production, causing an estimated US$80 - 118 billion per year in damage to crops. They are associated with nearly every important agricultural crop, and are a significant constraint on global food security. Regulations on the use of chemical pesticides have resulted in growing interest in alternative methods of nematode control. Future changes in climate, cropping systems, food habits, as well as social and environmental factors also affect the options for nematode control. Taking a systematic crop by crop approach, this book: Outlines the economic importance of specific plant parasitic nematode problems on the major food and industrial crops. Presents the state-of-the-art management strategies that have been developed to reduce specific nematode impacts, and outlines their limitations. Contains case studies to illustrate impact in the field. Aims to anticipate future changes in nematode disease pressure that might develop as a result of climate change, and new cropping systems.
