Many of the world's most serious agricultural pests are highly migratory. Through the use of special-purpose radars we are provided with insights into their movement and how they learn about and navigate through their environment. This text examines the behaviour and regional variations of these species, as well as the altitude of migration, concentration of insects in layers and how they respond to large and small-scale wind systems. The book relates radar observation of insect movement to complementary and competing methodologies and surveys its capabilities and limitations. It also deals wi

Knowledge of the flight behaviour of migrant insect pests is essential for an understanding of their population dynamics, which in turn determine the design of efficient management strategies. This bulletin provides a detailed review of the development of radar entomology, spanning the last 30 years, and its contribution to the study of major insect pests of agriculture and human health in the developing world. Pests include grasshoppers and locusts, the African armyworm, rice brown planthopper and other rice pests, the old world bollworm and some mosquito vectors of human diseases.

Knowledge of insect movement, particularly of flight, is crucial to our understanding of the great ecological and evolutionary success of insects. The last 20 years have seen many advances in this subject area. New fields have arisen, such as metapopulation theory, and dramatic developments have taken place in methods of studying movement, as a result of new techniques in molecular biology and radar monitoring. There have also been advances in our knowledge of flight-related physiology and behaviour. This book, which is based on the main papers presented at the Royal Entomological Society's 20th Symposium held in September 1999, brings us up to date with these developments.It contains chapters on:flight mechanismsforaging movementsmigrationthe evolution of movement strategiesthe interactions between dispersal rates, population structure and gene flow the effects of climate change on geographical distributionIt is essential reading for entomologists, and of interest to those researching animal behaviour, physiology, ecology and genetics.

This volume has come about as a direct result of a Symposium entitled "Experimental Analysis of Insect Behaviour" which was an important con tribution to the 14 International Congress of Entomology held in Canberra, Australia, in August 1972 under the joint sponsorship of the Australian Academy of Science and the Australian Entomological Society. It is not, however, strictly Symposium proceedings. I have included, in this volume contributions from several workers who had to withdraw from the Symposium at a fairly late stage. Furthermore, quite intentionally, a number of the contributions bear only a general relationship to the papers given at the Congress. To permit this; the deadline for contribu tions was set at some six months after the Symposium. I imposed no restrictions on the form of the contributions. I did, however, indicate that speculative reviews highlighting the author's own recent research or that of his immediate colleagues would be particularly acceptable, and a number of the contributors have taken the opportunity to write this kind of paper. Several contributors, notably those whose task it was to give more general papers in the Symposium itself, have written reviews of somewhat greater scope.

A comprehensive account of insect migration in its ecological and evolutionary context.

Set in the present day in the rural community of Feathertown, Tennessee, Flight Behavior tells the story of Dellarobia Turnbow, a petite, razor-sharp 29-year-old who nurtured worldly ambitions before becoming pregnant and marrying at seventeen. Now, after more than a decade of tending to small children on a failing farm, oppressed by poverty, isolation and her husband's antagonistic family, she has mitigated her boredom by surrendering to an obsessive flirtation with a handsome younger man. In the opening scene, Dellarobia is headed for a secluded mountain cabin to meet this man and initiate what she expects will be a self-destructive affair. But the tryst never happens. Instead, she walks into something on the mountainside she cannot explain or understand: a forested valley filled with silent red fire that appears to her a miracle. After years lived entirely in the confines of one small house, Dellarobia finds her path suddenly opening out, chapter by chapter, into blunt and confrontational engagement with her family, her church, her town, her continent, and finally the world at large.
