Download or read book Entomopathogenic Nematodes and Their Symbiotic Bacteria written by S. Sivaramakrishnan and published by Springer. This book was released on 2022-05-07 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Download or read book New Approaches for the Generation and Analysis of Microbial Typing Data written by L. Dijkshoorn and published by Elsevier. This book was released on 2001-07-10 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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..."

Download or read book Nematode Interactions written by M. Wajid Khan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Microbes for Sustainable Insect Pest Management written by Md. Aslam Khan and published by Springer Nature. This book was released on 2019-09-16 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Bob the Worm written by Hillel T. Schwartz and published by . This book was released on 2015-07-12 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
