Book Description
Novel 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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
In the period 1985-8, rains over much of Africa after a period of prolonged drought triggered the development of plague populations of grasshoppers and locusts. Countries from Senegal and Mauritania in the west to Iran in the east were affected. The use of costly and sometimes environmentally hazardous insecticides did contribute to the subsequent control of the problem, but highlighted the need for a reassessment of locust control methods. As a result, a collaborative programme was initiated in 1989 and undertaken by the International Institute of Biological Control of CAB International (CABI-IIBC), the Biological Control Program of the International Institute of Tropical Agriculture (IITA-BCP) and the Department of Crop Protection Training of the Permanent Inter-State Committee for Drought Control in the Sahel (CILSS-DFPV). Its main objective is to show the feasibility of killing locusts and grasshoppers using an oil-based formulation of a fungal pathogen.
