Entomopathogenic Nematodes Systematics Phylogeny And Bacterial Symbionts

The volume deals with history, morphology, taxonomy, and systematics of entomopathogenic nematodes (EPN) in the families Steinernematidae and Heterorhabditidae, molecular methods and bacteria associated with these nematodes.

Advances in Entomopathogenic Nematode Taxonomy and Phylogeny provides an account of the valid Steinernema and Heterorhabditis species proposed since 2007. A taxonomic overview, tabular key to species, and their phylogeny and phylogeography are provided.

The editors of this book, who are world renown for their creativity with entomopathogenic nematodes, have assembled the foremost authorities from four continents to contribute on basic and applied concepts. The authors have taken advantage of this opportunity to express their views to a wide scientific audience. They have combined their international experience so that the latest developments in this fascinating and rapidly expanding field are present in comprehensive manner with diverse topics ranging from biological control theory to organismal and molecular biology.

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.

Exploration in Laboratory Animal Sciences Understanding Life Phenomena updates our knowledge about the newer technologies such as molecular biology, genomics including sequencing, proteomics, transcriptomics, cell culture, stem cell culture, transgenesis and their translation to understand systematics and phylogeny of laboratory animals at molecular level. In seven sections Exploration in Laboratory Animal Sciences Understanding Life Phenomena resolves issues of conservation, applications in environment monitoring, production of drugs and others. Comparative research has enabled use of domestic animal models that translate the advances in basic biosciences to the schemes for human welfare including medicine. Molecular geneticists are unravelling the complexities of mammalian genes and the field of biotechnology is maturing at a fast pace. Additionally, research focused on immunology and animal behavior offer new insight into ways of enhancing animal welfare. The rise in consumption of animal proteins in addition to the challenges of sustaining our natural resources has given animal scientists a vast array of opportunities to engage in integrative systems-based research for meeting the challenges that behold us. Exploration in Laboratory Animal Sciences Understanding Life Phenomena also discusses the manipulation of animals as factories for the production of safe foods, drugs, and sensors and others to meet the contemporary challenges faced by mankind in the new world order created by pandemic of Covid 19. It also includes several chapters on the causation and management of certain diseases and impact of microbes on life. Provides insight to newer and futuristic technologies to understand disease process and drug design by animal models Addresses a wide variety of species and covers a wide variety of topics (such as animal species, the laboratory setting, regulatory guidelines, and ethical considerations) to fully prepare for work with all types of animals Gives a perspective on laboratory animal use that allows to explain the benefits of animal use as required by veterinary technology program accreditation procedure Includes examples of animal bio-technological techniques (including stem cell and tissue engineering) for their applications to humanity Offers new insight into ways of enhancing animal welfare by the inclusion of research results focused on immunology and laboratory animal behavior

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.

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.

This unique book contains not only a comprehensive up-to-date summary of the achievements made in all areas of Nematology in South Africa over more than half a century, but it also combines this rather technical part with an insiders narrative of how Nematology started and developed. It also demonstrates how the South African community of nematologists gradually adapted to major changes in agriculture. These were due to a major political shift followed by socio-economic changes and this in an often challenging natural environment. At the same time this book is conceived as a useful source for young scientists to provide them with practical knowledge and critical insight in the field of Nematology. The information given is based primarily on research conducted by nematologists in South Africa. Most of this research was aimed at finding workable solutions for nematological problems confronted by both large-scale commercial producers and smallholding farmers. During a period when funding for scientific research is becoming increasingly scarce, the future demand and quest for practical solutions by applied research will only increase.
