Our understanding of the physiological function of insect essential lipids has long been flawed by major uncertainties. It was discovered long ago that dietary sterol is a necessary nutrient for all insects, which radically sets them apart from the vertebrates in terms of qualitative nutrient requirements. Because of the physiological importance of sterol as a molting hormone precursor in insects and the implications of this for the development of new insecticides, a wealth of investigation into insect sterol metabolism followed, covering both the ways in which insects convert diverse food-plant sterols into the major tissue sterols and how these in turn are metabolized into the ecdysone molting hormones. However, for the classes or essential Lipid nutrients required by vertebrates, research dealing with insects has been scant and, more often than not, rather indeterminate. Many, but by no means all, insects studied appear to require essential fatty acids, though virtually nothing has been found out about the metabolism or essential physiological function of these acids. Excepting vitamin A, needed for insect vision, the various vertebrate fat-soluble vitamins appear to have no significance for insect physiology, and results of the occasional attempts to demonstrate functions for them in growth and development have in most cases been tantalizingly equivocal. In recent years some notable advances were made in tne study or essential fatty acids and fat-soluble vitamins in insects, and work on insect sterol nutrition and metabolism continues with ever-increasing sophistication. The contributors to this book summarize, discuss, and speculate on these issues. Their work is based on papers presented at the 1980 World Congress of Entomology at Kyoto, Japan.
Insect Physiology is currently undergoing a revolution with the increased application of molecular biological techniques to investigate the molecular mechanisms underlying the physiological responses to insect cells. Advances in Insect Physiology has instituted a commitment to the publication of high quality reviews on molecular biology and molecular genetics in areas where they provide an increased understanding of physiological processes in insects. Volume 24 is the first to include such specifically sought articles.
Based on nearly 40 years of teaching, this book thoroughly describes the principles and fundamentals of insect physiology. Readers will quickly understand the terminology needed to navigate the voluminous, scattered literature in the field. With approximately 1500 references and more than 240 figures and tables, Insect Physiology and Biochemistry is useful as a core text for upper division and graduate students, as well as a valuable reference for scientists who work with insects in genetics, biochemistry, virology, microbiology, and behavior.
This book discusses recent contributions focusing on insect physiology and ecology written by experts in their respective fields. Four chapters in this book are dedicated to evaluating the morphological and ecological importance and distribution of water beetles, dung beetles, weevils, and tabanids, while two others investigate the symbiotic relationships between various insects and their associations with bacteria, fungi, or mites. Two other chapters consider insecticide detoxification, as well as insect defense mechanisms against infections. The last two chapters concentrate on insects as sustainable food. This book targets a wide audience of general biologists, as well as entomologists, ecologists, zoologists, virologists, and epidemiologists, including both teachers and students in gaining a better appreciation of this rapidly growing field.
Insects as Sustainable Food Ingredients: Production, Processing and Food Applications describes how insects can be mass produced and incorporated into our food supply at an industrial and cost-effective scale, providing valuable guidance on how to build the insect-based agriculture and the food and biomaterial industry. Editor Aaron Dossey, a pioneer in the processing of insects for human consumption, brings together a team of international experts who effectively summarize the current state-of-the-art, providing helpful recommendations on which readers can build companies, products, and research programs. Researchers, entrepreneurs, farmers, policymakers, and anyone interested in insect mass production and the industrial use of insects will benefit from the content in this comprehensive reference. The book contains all the information a basic practitioner in the field needs, making this a useful resource for those writing a grant, a research or review article, a press article, or news clip, or for those deciding how to enter the world of insect based food ingredients. Details the current state and future direction of insects as a sustainable source of protein, food, feed, medicine, and other useful biomaterials Provides valuable guidance that is useful to anyone interested in utilizing insects as food ingredients Presents insects as an alternative protein/nutrient source that is ideal for food companies, nutritionists, entomologists, food entrepreneurs, and athletes, etc. Summarizes the current state-of-the-art, providing helpful recommendations on building companies, products, and research programs Ideal reference for researchers, entrepreneurs, farmers, policymakers, and anyone interested in insect mass production and the industrial use of insects Outlines the challenges and opportunities within this emerging industry
Biochemistry of Insects reviews the state of knowledge in insect biochemistry. The book begins by examining the function of carbohydrates in regulating and maintaining the life processes of insects. This is followed by separate chapters on the functional roles of lipids and proteins in insects; and protein synthesis in insects. Subsequent chapters cover the chemistry of insect cuticle; the structure, distribution, and chemistry of insect biochromes; and chemical control of insect behavior. Also discussed are the biochemical aspects of the natural products used by insects in defensive contexts; the reaction of insecticides and related compounds with their targets; detoxification mechanisms in insects; and genetic variation in natural populations. Designed to serve as a basic textbook in field, this volume should be equally useful as an auxiliary text for most relevant courses in insect biology, particularly insect physiology, insect ecology, insect control, and economic entomology. The book should also serve as an important reference source for the advanced student, the research scientist, and the professional entomologist seeking authoritative details of relevant areas of subject matter.
Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Dr. Allen Carson Cohen's new edition of Insect Diets: Science and Technology continues to provide a current, integrated review of the field of insect diets. It reaffirms and expands upon the belief that the science of diet development and the technology of diet application in rearing programs require formal foundations and guidelines. Cohen argues
