Nematodes that are parasites of insects are no longer a laboratory curiosity. They have begun to be accepted as environmentally benign alternatives to the use of chemical insecticides, for the control of insect pests. Nematode worms are now applied as biological control agents against insectpests of numerous horticultural and agricultural crops. This book provides a comprehensive review of entomopathogenic nematology. It begins by reviewing fundamental biology and setting a taxonomic foundation for nematodes and their bacterial symbionts. Several chapters are devoted to functionalprocesses involved in parasitism and to nematode ecology. Later chapters describe technological advances and control methodologies.

In Advances in Entomopathogenic Nematode Taxonomy and Phylogeny the numerous species of Steinernema and Heterorhabditis described 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 Steinernema and Heterorhabditis assist in diagnostics. A chapter on phylogeny and phylogeography completes the book.

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.

This book describes entomopathogenic and slug parasitic nematodes as potential biocontrol agents in crop insect and slug pest management. Addressing research on these two nematodes from tropical, subtropical and temperate countries, it covers the new techniques and major developments regarding mass production, formulation, application, commercialization and safety measures. Plans for future strategies to make these beneficial nematodes cost-effective and expand their use by including them in integrated pest management programmes in different agro-ecosystems are also discussed. Biocontrol Agents: Entomopathogenic and Slug Parasitic Nematodes provides a comprehensive review of the topic and is an essential resource for researchers, industry practitioners and advanced students in the fields of biological control and integrated pest management.

This book provides basic information and different protocols associated with the Entomopathogenic nematodes (EPNs) and their symbiotic bacteria. Entomopathogenic nematodes (EPNs) of the genera Steinernema and Heterorhabditis and their associated bacterial symbionts Xenorhabdus and Photorhabdus aid nematode infective juveniles (IJs) in infecting and killing their insect hosts, creating a unique tripartite complex of host-vector-symbiont interactions. Due to this insect killing capability, EPNs are used as biological control agents of economically important insect pests. They are also a model system to study host-parasite interactions. It provides a systematic approach to various nematode procedures including pathogenicity, reproduction, foraging behaviour. It gives a brief outline on historical aspects, nematode-bacterium complex, biology and chemical ecology of EPNs. It concisely describes host insect rearing, nematode sampling and storage, isolation techniques, counting, handling and staining of nematodes, characterization including morphological, molecular and ecological studies, mass production, virulence bioassay, field application and efficacy. The book also includes methods and techniques for their associated symbiotic bacteria. This book serves as a laboratory manual and assists the readers to undertake advanced research in different aspects related to nematodes. It is useful for researchers in the fields of nematology, microbiology, bacteriology and entomology.

Achieving a sustainable agriculture requires integrating advances in multiples disciplines, covering both fundamental and applied research in a common objective: enhancing crop health for better productions. This first volume of the Series “Sustainability in plant and crop protection” presents a comprehensive and multi-disciplinary compendium about the recent achievements in the use of entomopathogenic nematodes (EPNs) as biological control in a global scale. The volume is organized in a first section discussing the last discoveries on the biology and ecology of the EPN, a second section covering the advances on the EPN productions and release, and a third section with multiples case-studies in which the concepts and ideas on the two previous sections are integrated and discussed. An essential tool for researchers and professionals working to advance in the sustainable use of our resources.

Nematodes are one of the most abundant groups of invertebrates on the face of the earth. Their numbers are estimated to range from 1000 per cm2 in the sand-covered hydrogen sulphide ‘black zone’ beneath the ocean floors to 1.2 billion in a single hectare of soil. Estimates for their species diversity range from 100 000 to 10 million. The past history of nematodes is a mystery, since very few fossils have been discovered. This book establishes a solid base in palaeonematology with descriptions of 66 new fossil species and accounts of all previous fossil and subfossil nematodes from sedimentary deposits, coprolites, amber and mummies. It shows how nematode fossils can be used to establish lineages at various locations and time periods in the earth’s history and when nematodes entered into symbiotic and parasitic associations with plants and animals.

Biological Techniques is a series of volumes aimed at introducing to a wide audience the latest advances in methodology. The pitfalls and problems of new techniques are given due consideration, as are those small but vital details not always explicit in the methods sections of journal papers.In recent years, most biological laboratories have been invaded by computers and a wealth of new DNA technology and this will be reflected in many of the titles appearing in the series.The books will be of value to advances researches and graduate students seeking to learn and apply new techniques, and will be useful to teachers of advanced undergraduate courses involving practical or project work.This manual describes the broad array of techniques that are used in insect pathology. It will provide biologists, insect pathologists, entomologists, and those interested in biological control, with the necessary information to work on a variety of pathogen groups.This book will be an essential laboratory reference for insect pathologists.Features include:* Step by-step instructions on how to isolate, identify, culture, bioassay and store the major groups of entomopathogens* Details of the practical knowledge needed by beginners to apply the techniques* Chapters written by an international group of experts* Discussion of safety testing of entomopathogens in mammals and also broader methods such as microscopy and molecular techniques* Provides extensive supplemental literature and recipes for media, fixatives and stains
