Biology Of Blood Sucking Insects

Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.

Second edition looks at the favourable biological modifications of these insects and also considers the economical, social and medical aspects.

Insect Biology in the Future: ""VBW 80"" contains essays presented to Sir Vincent Wigglesworth during his 80th year. Wigglesworth is fairly designated as the founding father and remarkable leader of insect physiology. His papers and other works significantly contribute to this field of study. This book, dedicated to him, underlines the value of insect material in approaching a wide spectrum of biological issues. The essays in this book tackle the insects' physiology, including their evolution and dominance. The papers also discuss the various avenues of water loss and gain as interrelated components of overall water balance in land arthropods. This reference suggests possible areas for further research mainly at the whole animal level. It also describes the fat body, hemolymph, endocrine control of vitellogenin synthesis, reproduction, growth, hormones, chemistry, defense, and survival of insects. Other topics of importance include cell communication and pattern formation in insects; plant-insect interaction; and insecticides.

The only book to deal comprehensively with insect feeding was published by C. T. Brues in 1946. His Insect Dietary was an account of insect feeding habits. Since that time there has been a revolution in biology, and almost all aspects of our understanding of insect feeding have expanded to an extent and into areas that would have been unthinkable in Brues' day. Yet, our book does not replace Insect Dietary but, instead, complements it, because our aim is to bring together information on the mechanisms by which food quality and quantity are regulated. We deliberately focus attention on the feeding process; to include food-finding would have required a much larger book and would have moved the focus away from more proximate mechanisms. This book is dedicated to the late Vincent G. Dethier. As a pioneer in studying the physiological basis of animal behavior, he focused on regulation of feeding in flies and caterpillars. His work on the blowfly, together with that by his many students and co-workers, still provides the most completely described mechanism of insect feeding. The citation of his work in almost every chapter in this book illustrates the importance of his findings and ideas to our current understanding of regulation of insect feeding. The authors in this book provide many innovative and stimulating ideas typifying Dethier's approach to the study of feeding be havior.

Medical and Veterinary Entomology, Second Edition, has been fully updated and revised to provide the latest information on developments in entomology relating to public health and veterinary importance. Each chapter is structured with the student in mind, organized by the major headings of Taxonomy, Morphology, Life History, Behavior and Ecology, Public Health and Veterinary Importance, and Prevention and Control. This second edition includes separate chapters devoted to each of the taxonomic groups of insects and arachnids of medical or veterinary concern, including spiders, scorpions, mites, and ticks. Internationally recognized editors Mullen and Durden include extensive coverage of both medical and veterinary entomological importance. This book is designed for teaching and research faculty in medical and veterinary schools that provide a course in vector borne diseases and medical entomology; parasitologists, entomologists, and government scientists responsible for oversight and monitoring of insect vector borne diseases; and medical and veterinary school libraries and libraries at institutions with strong programs in entomology. Follows in the tradition of Herm's Medical and Veterinary Entomology The latest information on developments in entomology relating to public health and veterinary importance Two separate indexes for enhanced searchability: Taxonomic and Subject New to this edition: Three new chapters Morphological Adaptations of Parasitic Arthropods Forensic Entomology Molecular Tools in Medical and Veterinary Entomology 1700 word glossary Appendix of Arthropod-Related Viruses of Medical-Veterinary Importance Numerous new full-color images, illustrations and maps throughout
