Download or read book Insect Endocytobiosis written by Werner Schwemmler and published by CRC Press. This book was released on 1989-10-31 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of contributions from leading scientists in the field of intracellular symbiosis research outlining the present status of endocytobiosis studies on the most important groups of insects. Emphasis is on the results of ex-perimental symbiosis research on the morphology, physiology, and genetics of selected insect groups. Insights provided by the new interdisciplinary research field of endocytobiology is considered in interpreting experimental results of symbiology. Various insect endocytobionts are discussed with regard to their evolutionary development, reflecting the current status of evolution research. Special attention is given to the phylogenetic and systematic classification of endocytobionts. Also discussed in comparison with the similar system of ticks are all endosymbioses found in roaches, termites, ants, cicadas, coccids, aphids, flies, and beetles.
Download or read book Insect Pathology written by Yoshinori Tanada and published by Academic Press. This book was released on 2012-12-02 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect Pathology is designed for a broad spectrum of readers. Is should be useful to students, lecturers, and researchers requiring information about the principles in insect pathology and the biology of pathogens. It should serve as a resource for specialists to learn about other insect pathogen systems, for generalists to become aware of advances in insect pathology, and for scientists and students, beginning or otherwise, interested in learning about insect pathology. This book was originally intended to update the 1949 test by E. A. Steinhaus entitled Principles of Insect Pathology. The purpose for this book was twofold: To serve (1) as a text for an insect pathology and/or biological control class and (2) as a comprehensive reference source. Because this book summarizes much of the available information, its usefulness as a textbook for an insect pathology class is apparent. Although the literature citations are extensive, they are far from complete. The literature in insect pathology is voluminous and for the past decade has been expanding at an almost exponential rate. A complete review of the literature is beyond the scope of the book, and an omission of a reference does not preclude its importance. Our citations, however, should serve as a good starting point for those who wish to obtain further information. We have attempted to cover equally all subdisciplines, but shortcomings are unavoidable. For these, we take full responsibility.

Download or read book Insect Fungal Associations written by Fernando E. Vega and published by Oxford University Press. This book was released on 2005-02-03 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects and fungi have a shared history of association in common habitats where together they endure similar environmental conditions, but only recently have mycologists and entomologists recognized and had the techniques to study the intricacies of some of the associations. This new volume covers "seven wonders of the insect-fungus world" for which exciting new results have become available, often due to the use of new methods that include phylogenetic analysis and development of molecular markers. Eleven chapters of the volume are presented in two sections, "Fungi that act against insects" and "Fungi mutualistic with insects" that cover a number of major themes. Examples of necrotrophic parasites of insects are discussed, not only for biological control potential, but also as organisms with population structure and complex multipartite interactions; a beneficial role for symptomless endophytes in broad-leafed plants is proposed; biotrophic fungal parasites with reduced morphologies are placed among relatives using phylogenetic methods; complex methods of fungal spore dispersal include interactions with one or more arthropods; the farming behavior of New World attine ants is compared with that of humans and the Old World fungus-growing termites; certain mycophagous insects use fungi as a sole nutritional resource; and other insects obtain nutritional supplements from yeasts. Insects involved in fungal associations include--but are not limited to--members of the Coleoptera, Diptera, Homoptera, Hymenoptera, and Isoptera. The fungi involved in interactions with insects may be clustered taxonomically, as is the case for Ascomycetes in the Hypocreales (e.g., Beauveria, Metarhizium, Fusarium), ambrosia fungi in the genera ophiostoma and ceratocystis and their asexual relatives, Laboulbeniomycetes, Saccharomycetes, and the more basal Microsporidia. Other groups, however, have only occasional members (e.g., mushrooms cultivated by attine ants and termites) in such associations. The chapters included in this volume constitute a modern crash course in the study of insect-fungus associations.
Download or read book Insect Bioecology and Nutrition for Integrated Pest Management written by Antônio Ricardo Panizzi and published by CRC Press. This book was released on 2012-03-08 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of insect nutritional ecology has been defined by how insects deal with nutritional and non-nutritional compounds, and how these compounds influence their biology in evolutionary time. In contrast, Insect Bioecology and Nutrition for Integrated Pest Management presents these entomological concepts within the framework of integrated pest management (IPM). It specifically addresses bioecology and insect nutrition in modern agriculture. Written for graduate students and professionals in entomology, this book covers neotropical information in three sections: General Aspects: Basic bioecology and insect nutrition; artificial diets; insect/plant interactions; insect symbionts; the interface of chemical ecology with the food; and insect cannibalism Specific Aspects: Specific feeding guilds of insects including ants, social bees, leaf chewers, seed suckers, seed chewers, root feeders, gall makers, detritivorous feeders, pests of storage grains, fruit flies, aphids, endo- and ectoparasitoids, predators, crisopids, and hematophagous insects Applied Aspects: Host plant resistance and the design of IPM programs in the context of insect bioecology and nutrition Much of the research on which these chapters were written was done in Brazil and based on its neotropical fauna. The complexity and diversity of the neotropics provides enough data that readers from all zoogeographical regions can readily translate the information in this book to their specific conditions. The book’s value as an entry point for further research is enhanced by the inclusion of approximately 4,000 references.
Download or read book Cell to Cell Signals in Plant Animal and Microbial Symbiosis written by Silvano Scannerini and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: In symbiosis, different organisms have to recognize each other and exchange material and information. While the functional morphology of symbiont cells has extensively been studied little attention has been paid to mutual interactions and cell-to-cell signals. The main topic of the book is the comparison and discussion of the short-distance signals triggering mutualism in animal and plant cells. Thus it provides a) the basis for a better understanding of various aspects of cell compatibility; b) standardisation of a common vocabulary for animal and plant symbiotic biology; c) optimization of experimental techniques for studying signals in symbiosis. The results show the differences and the general principles in the signalling processes of plant, animal and bacterial cells.
Download or read book Insect Microbiome From Diversity To Applications written by George Tsiamis and published by Frontiers Media SA. This book was released on 2023-03-21 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are by far the most diverse and abundant animal group with respect to the number of species globally, in ecological habitats and in biomass. The ecological and evolutionary success of insects depends in part on their countless relationships with beneficial microorganisms, which are known to influence all aspects of their physiology, ecology, and evolution. These symbiotic associations are known to: (a) enhance nutrient-poor diets, (b) aid digestion of recalcitrant food components, (c) protect from predators, parasites, and pathogens, (d) contribute to inter- and intraspecific communication, (e) affect efficiency as disease vectors and (f) govern mating and reproductive systems. Characterization, exploitation, and management of the insect-bacterial symbiotic associations can contribute significantly to the control of agricultural pests and disease vectors. Insects that depend exclusively on nutritionally restricted diets such as plant sap, vertebrate blood, and woody material, commonly possess obligate mutualistic endosymbionts involved in the provision of essential nutrients or in the degradation of food materials. These intracellular mutualists commonly have the following biological features: (a) they localize inside bacteriocytes, (b) are essential for fitness, (c) are maternally transmitted, and (d) display strict host-symbiont co-evolutionary patterns. In addition to obligate endosymbionts, many insects harbor bacteria that are not essential for their survival or fecundity and are typically maintained with a patchy distribution in host populations. Such symbionts can induce reproductive phenotypes in insect hosts, including male-killing, feminization, parthenogenesis or cytoplasmic incompatibility. Because these bacteria manipulate their host’s reproductive biology, they also likely accelerate host processes. As for essentially all animals, microbial communities are particularly prominent in the digestive tract, where they may be key mediators of the varied lifestyles of insect hosts. The contribution of microorganisms, particularly gut microorganisms, to insect function is highly relevant from several perspectives, linking to applications in medicine, agriculture, and ecology. Gut-associated microorganisms can include protists, fungi, archaea, and bacteria, but it is generally accepted that bacterial species dominate the microbial community in the guts of most insects. Gut-associated bacteria can influence: (a) vectoring efficiency, (b) developmental time, (c) decomposition of plant biomass and carbon cycle, (d) nitrogen fixation and nitrogen cycle, (e) mating incompatibilities, and (f) detoxification of pesticides leading to the acquisition of insecticide resistance.

Download or read book Enigmatic Microorganisms and Life in Extreme Environments written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern methods and approaches, such as the analysis of molecular sequences to infer evolutionary relationships among organisms, have provided vast new sets of data to further our understanding ofliving organisms, but there remain enigmas in the biological world that will keep scientists working and thinking for decades. Microorganisms by virtue of their small size and almost unbounded diversity provide ample examples of intriguing mysteries that are being challenged with all of the techniques the modern scientific arsenal can provide. One whole arena of this battle to resolve puzzling mysteries about various microorganisms is the almost unbelievable ability of many micro-organisms to live in extreme environments. Whether the challenge is extreme heat, cold, pressure, hyper salinity, alkalinity or acidity, some micro-organisms live now where no life might seem possible. This fascinating state of affairs is the context for this present volume edited by Joseph Seckbach. This Volume is a compilation of many of the especially interesting questions and biological challenges that arise in the consideration of microorganisms in general and the extremophiles in particular.

Available in PDF, EPUB and Kindle. Book excerpt: These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty.A departure from mainstream biology, the idea of symbiosis--as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals--has attracted the attention of a growing number of scientists.These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal-bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution. ContributorsPeter Atsatt, Richard C. Back, David Bermudes, Paola Bonfante-Fasolo, René Fester, Lynda J.
