The Entomopathogenic Nematode Heterorhabditis Megidis by M. I. C. Boff Pdf

The aim of the research presented in this thesis was to investigate the effects of biotic and abiotic factors on the biology and ecology of Heterorhabditis megidis (strain NLH-E87.3, Smits et al., 1991) a common, but little studied entomopathogenic nematode in the Netherlands. Particular attention was paid to the searching behaviour of this nematode strain. Entomopathogenic nematodes are a welcome addition to the natural-enemy pool of insects and can be integrated with various control measures for management of those target pests where individual tacticsalone are inadequate. Entomopathogenic nematodes play a role underground reminiscent of that played by insect parasitoids, arthropod predators and microbial pathogens above ground. Like parasitoids or predators, they have chemoreceptors and are motile; like pathogens, they are highly virulent, killing their hosts quickly, and can be cultured easilyin vivo or in vitro (Ehlers, 1996).

Entomopathogenic Nematology by Randy Gaugler Pdf

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 the past two decades, tremendous advances have been achieved in developing technology for producing these organisms. Despite that and the globally growing research and interest in biological control and biotechnology applications, commercialization of these technologies is still in progress. This is an essential reference and teaching tool for researchers in developed and developing countries working to produce “natural enemies in biological control and integrated pest management programs. Highlights the most advanced and current techniques for mass production of beneficial organisms and methods of evaluation and quality assessment Presents methods for developing artificial diets and reviews the evaluation and assurance of the quality of mass-produced arthropods Provides an outlook of the growing industry of insects as food and feed and describes methods for mass producing the most important insect species used as animal food and food ingredients

Ecofriendly Pest Management for Food Security by Omkar Pdf

Ecofriendly Pest Management for Food Security explores the broad range of opportunity and challenges afforded by Integrated Pest Management systems. The book focuses on the insect resistance that has developed as a result of pest control chemicals, and how new methods of environmentally complementary pest control can be used to suppress harmful organisms while protecting the soil, plants, and air around them. As the world’s population continues its rapid increase, this book addresses the production of cereals, vegetables, fruits, and other foods and their subsequent demand increase. Traditional means of food crop production face proven limitations and increasing research is turning to alternative means of crop growth and protection. Addresses environmentally focused pest control with specific attention to its role in food security and sustainability. Includes a range of pest management methods, from natural enemies to biomolecules. Written by experts with extensive real-world experience.

Entomopathogenic Nematodes and Their Symbiotic Bacteria by S. Sivaramakrishnan,M. Razia Pdf

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.

Nematodes as Biocontrol Agents by Parwinder S. Grewal,Ralf-Udo Ehlers,David I. Shapiro-Ilan Pdf

This book documents and illustrates major developments in the use of nematodes for the biological control of insects and slugs. It covers the use of three main types of nematodes: entomopathogenic nematodes, entomophilic nematodes and slug-parasitic nematodes. The biology, commercial production, formulation and quality control, application technology, strategy and safety of each of these three nematode groups is discussed. The book also examines the application of nematodes in different cropping systems, and the efficacy of nematodes against specific pests. The potential of predatory nematodes to control plant-parasitic nematodes and mycophagous nematodes to control fungal pathogens is also reviewed.
