Available in PDF, EPUB and Kindle. Book excerpt: In 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.

Download or read book Biology Ecology and Systematics of Australian Scelio written by Paul Dangerfield and published by CSIRO PUBLISHING. This book was released on 2001-12-01 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic wasps of the genus Scelio play an important role in the regulation of orthopteran populations and are implicated in suppressing numbers of numerous pest locusts and grasshoppers. This landmark volume provides a full taxonomic treatment of the sixty species of Scelio found on the Australian continent and reviews in detail the biology and ecology and host relationships of Scelio on a worldwide basis. Taking an international perspective, the text outlines our current knowledge on topics such as host finding, population biology, and methods and techniques for collection and study in the field. The use of Scelio as biological control agents is discussed and comprehensive checklists document the recorded host relationships of each known species worldwide. There is a full taxonomic revision of all Australian species of Scelio, half of which are newly described. Each species description is complemented with high-quality line drawings, micrographs and distribution maps. In addition, an illustrated key to species enables easy identification of species by non-taxonomists. Biology, Ecology and Systematics of Australian Scelio provides wasp taxonomists, researchers of orthoptera and biological control workers with a basis for detailed studies elsewhere on this economically important group of insects.
Download or read book Locust written by Jeffrey A. Lockwood and published by Basic Books. This book was released on 2009-04-28 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the nineteenth century, swarms of locusts regularly swept across the continent, turning noon into dusk, demolishing farm communities, and bringing trains to a halt as the crushed bodies of insects greased the rails. In 1876, the U.S. Congress declared the locust "the single greatest impediment to the settlement of the country." From the Dakotas to Texas, from California to Iowa, the swarms pushed thousands of settlers to the brink of starvation, prompting the federal government to enlist some of the greatest scientific minds of the day and thereby jumpstarting the fledgling science of entomology. Over the next few decades, the Rocky Mountain locust suddenly -- and mysteriously -- vanished. A century later, Jeffrey Lockwood set out to discover why. Unconvinced by the reigning theories, he searched for new evidence in musty books, crumbling maps, and crevassed glaciers, eventually piecing together the elusive answer: A group of early settlers unwittingly destroyed the locust's sanctuaries just as the insect was experiencing a natural population crash. Drawing on historical accounts and modern science, Locust brings to life the cultural, economic, and political forces at work in America in the late-nineteenth century, even as it solves one of the greatest ecological mysteries of our time.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores the profound importance of phenotypic plasticity as a central organizing theme for understanding biology. Chapters take a broad, integrative approach to explain how physical and biological environmental stimuli (temperature, photoperiod, nutrition, population density, predator presence, etc.), influence insect biochemical, physiological, learning, and developmental processes, altering phenotype, which then influences performance, ecology, life-history, survival, fitness, and subsequent evolution. Topics include endocrinology, development, body size, allometry, polyphenism, reproduction, reproductive and life-history tradeoffs, alternative mating and life-history strategies, density-dependent prophylaxis, physiological adaptation, acclimation, homeostasis, heat-shock proteins, learning, adaptive anti-predator behavior, and evolution of phenotypic plasticity.

This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acridids (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.

Book excerpt: The acridoid grasshoppers in general and the various species of swarm-forming locusts in particular have been among the most favoured subjects of insect physi ology, behaviour and ecology for many years. Several factors contribute to this popularity: their abundance in nature and their ease of culture in the laboratory, their relatively large size, and most of all, perhaps, their agricultural importance and the consequent intermittent availability of funds for their study. These factors together have inspired a large amount of experimental work, and this in tum has produced a new and often over-riding reason for working on acridoids -the huge body of available background information and know-how that has built up about these insects. This state of affairs is well seen in insect neurobiology. Only a restricted number of insect types are commonly used in this discipline, and originally most of them were selected for reasons of convenience and availability: grasshoppers, cock roaches, crickets, flies, bees and moths are the most important. Each of these in sects is the subject of the attentions of one or more major groups of neurobiolo gists, but neurobiological articles on acridoids probably exceed in number those on all other insects combined, at least if articles on the molecular biology of the nervous system of Drosophila are excluded.
