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 behavior. 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 mechanisms, foraging movements, migration, the evolution of movement strategies, the interactions between dispersal rates, population structure and gene flow the effects of climate change on geographical distribution. It is essential reading for entomologists, and of interest to those researching animal behavior, physiology, ecology and genetics.

Many of the world's most serious agricultural pests are highly migratory and 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 behavior 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 with the applications of these findings in the management and forecasting of both pest and beneficial insects, and will be an essential reference for those working in agricultural entomology and pest management.

Drama starring Myrna Loy and Robert Mitchum, based on a screenplay adapted by John Steinbeck from his early novel of the same name. Ten-year-old Tom Tiflin (Peter Miles) lives on a ranch in California's Salinas Valley with his mother (Loy), recently-returned father (Sheppard Strudwick), maternal grandfather (Louis Calhern) and handsome hired hand Billy Buck (Mitchum). In an attempt to get closer to his son after his long absence from the ranch, Tom's father gives him a much longed-for pony. But as the pony becomes the central focus of Tom's life, the family is driven apart as Tom turns to Billy for help with rearing it.
