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.

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.

Bob the Worm by Hillel T. Schwartz Pdf

"Bob the worm" is a lighthearted,cartoonish look at how one type of worms live in the wild: they hunt down insects that they will use as their home and as food, before their descendants repeat the process several generations later. See the whole book (in low resolution) at: https://youtu.be/fdm5RmfMdG0 Although written as a kid's book, the biology described is real: entomopathogenic nematodes (roundworms) of the genus Heterorhabditis infect, infest, and consume insects, relying on a partnership with symbiotic bacteria essential to their survival and success. These bacteria kill the insect, defend the carcass from other microorganisms and other predators, and provide a food source for the Heterorhabditis nematode; in turn, when the carcass is crowded the worms will disperse in search of new insect hosts, each carrying bacteria that could neither survive in the soil nor infect new insects without them. The book gives a simplified and friendly presentation of this life cycle, and offers an opportunity to discuss what is happening in the natural world around us every day.

New Approaches for the Generation and Analysis of Microbial Typing Data by L. Dijkshoorn,K.J. Towner,Mark J Struelens Pdf

Rapid molecular identification and typing of micro-organisms is extremely important in efforts to monitor the geographical spread of virulent, epidemic or antibiotic-resistant pathogens. It has become a mainstay of integrated hospital infection control service. In addition, numerous industrial and biotechnological applications require the study of the diversity of organisms. Conventional phenotypic identification and typing methods have long been the mainstay of microbial population and epidemiological studies, but such methods often lack adequate discrimination and their use is normally confined to the group of organisms for which they were originally devised. Molecular fingerprinting methods have flourished in recent years and many of these new methods can be applied to numerous different organisms for a variety of purposes. Standardisation of these methods is vitally important. In addition, the generation of large numbers of complex fingerprint profiles requires that a computer-assisted strategy is used for the formation and analysis of databases. The purpose of this book is to describe the best fingerprinting methods that are currently available and the computer-assisted strategies that can be used for analysis and exchange of data between laboratories. This book is dedicated to the memory of Jan Ursing (1926 - 2000), Swedish microbiologist, taxonomist and philosopher. "...taxonomy is on the borders of philosophy because we do not know the natural continuities and discontinuities..."

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).

Nematode Interactions by M. Wajid Khan Pdf

Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

Microbes for Sustainable Insect Pest Management by Md. Aslam Khan,Wasim Ahmad Pdf

This Volume comprises 14 chapters in an attempt to provide the reader with available information on safe and effective use of entomopathogens. Chapters in this book dealing with soil-borne entomopathogens and their phylogeny also provide a review on most updated information of their isolation and molecular identification. Employing fungal pathogens in biological control programmes plays a key role, and conidial thermotolerance and oxidative stress are examined in separate chapters. Entomopathogenic bacteria are able to kill their hosts quickly. An important contribution concerns informations provided upon bacterial cytotoxic factors on insect haemocytes. Nematodes are biological control agents safe to the environment. The information with respect to their direct and indirect effects on non-target organisms is provided. Viruses as highly specific, virulent candidates for use as biological insecticides are safe to non-target species. A separate chapter on the role of granuloviruses in IPM contributes a wealth of information. Biopesticides in combination with synthetic insecticides are reported as effective, economic, and eco-friendly. Understanding their interactions will certainly promote their uses. Finally, emphasis has been given on reviewing synergistic and antagonistic interactions of microbial and chemical pesticides, in other chapters.
