DOWNLOAD EBOOKNovel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah Letourneau This volume represents the forefront of two rapidly advancing areas of ecology: three-trophic-level interactions and the interdisciplinary field of chemical ecology The book focuses on the role of microorganisms as mediators of interactions between insects and plants, providing critical appraisal of studies and suggesting ways to integrate competing hypotheses of insect-plant dynamics. 1988 (0 471-83276-6) 362 pp. Arthropod Biological Control Agents and Pesticides Brian A. Croft Examining the effects of pesticides on predators and parasites and exploring methods for reducing negative impacts of pesticide use, this book focuses on the interaction of pesticides with entomophagous arthropods. It surveys the history of research in the field and discusses susceptibility assessment, lethal, sublethal, and ecological effects of pesticides, and selectivity, resistance, and resistance management. 1990 (0 471-81975-1) 723 pp. Lepidopteran Anatomy, John Eaton This single-source treatment on the anatomy of Lepidoptera provides a detailed exposition of its anatomy plus all its life stages, including the larva and adult forms of the exoskeleton, musculature, organ systems, and specialized structures. As the only thorough examination of the morphology of this insect group, it is an essential acquisition for entomologists, morphologists, and insect physiologists. 1988 (1-05862-9) 257 pp. Integrated Pest Management Systems and Cotton Production Edited by Ray Frisbie, Kamal El-Zik, and L. Ted Wilson The most complete and authoritative work available on the subject, this book brings together information on integrated pest management strategies that are applicable to cotton. It addresses economic, agronomic, and biological factors of pest management and focuses on plant resistance to pests and the genetic rationale for improving plant health. 1989 (0 471-81782-1) 437 pp.

DOWNLOAD EBOOKAcridids (grasshoppers and locusts) can range from being rare curiosities to abundant menaces. Some are threatened with extinction and become subjects of intensive conservation efforts, while others are devastating pests and become the objects of massive control programmes. Even within a species, there are times when the animal is so abundant that its crushed masses cause the wheels of trains to skid (the Rocky Mountain grasshopper, Melanoplus spretus Walsh in western North America in the 1860s and I 870s), while at other times the animal is alarmingly scarce (the Rocky Mountain grasshopper went extinct in the early 1900s). Why are there these extremes in one insect family, and even in a single species? The NATO workshop examined this paradox and its implications for Environmental Security, which must address both the elements of land use (agricultural production and pest management) and conservation of biodiversity. The reconciliation of these objectives clearly demands a critical assessment of current knowledge and policies, identification of future research, and close working relationships among scientists. Insects can present two clear faces, as well as the intervening gradation. These extremes require us to respond in two ways: conservation of scarce species and suppression of abundant (harmful) species. But perhaps most important, these opposite poles also provide the opportunity for an exchange of information and insight.

DOWNLOAD EBOOKThe Physiology of Insecta, Second Edition, Volume V, is part of a multivolume treatise that brings together the known facts, the controversial material, and the many unresolved and unsettled problems of insect physiology. It features chapters written by the outstanding workers in each of a wide range of insect function areas. It is designed to meet a manifest need, which has arisen from the phenomenal increase in research activity on insects, for an authoritative, comprehensive reference work in insect physiology. The book begins with a discussion of insect nutrition. This is followed by separate chapters on the physiology of digestion and absorption; the factors affecting insect heart rates; the electrical properties of the insect heart; and the hemocytes of insects. Subsequent chapters cover the physiological role and the adaptive significance of the main biochemical constituents of insect hemolymph; salt and water balance in insects; defense reactions in insects; and microsomal mixed-function oxidases.

DOWNLOAD EBOOKIn the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.
