This volume is an outgrowth of a Symposium entitled "Evolution of Escape in Space and Time" held at the XV International Congress of Entomology in Washington, D. C., USA in August, 1976. The choice of topic was prompted by recent advances in evolutionary ecology and the apparent suitability of insect migration and dia pause as appropriate material for evolutionary studies. In the event, that choice seems amply justified as I hope a perusal of these papers will show. These Sympos ium papers hardly cover the topic of the evolution of escape mechanisms exhaustively, and I am sure everyone will have his favorite lacuna. Some of the more obvious ones are indicated by Professor Southwood in his Concluding Remarks at the end of the book. The purpose of the Symposium, however, was not complete coverage, but rather to indicate the potential inherent in insect migration and diapause for the study of evolutionary problems. In that I think we have succeeded reasonably well. These papers are expanded and in some cases somewhat altered versions of the papers delivered in Washington. This has allowed greater coverage of the topics in question. I suggested a format of a general overview of a topic emphasizing the author's own research con tributions. In general the papers follow this outline although emphases vary. Two of the authors, Dr. Rainey and Dr. Lumme, were unable to attend the Symposium. Dr. Rainey's paper was read by Mr. Frank Walsh, but Dr.

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

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

"This timely book reveals how the increase in traffic of transpacific plants, insects, and peoples raised fears of a "biological yellow peril" beginning in the late nineteenth century, when mass quantities of nursery stock and other agricultural products were shipped from large, corporate nurseries in Japan to meet the growing demand for exotics in the United States. Jeannie Shinozuka marshals extensive research to explain how the categories of "native" and "invasive" defined groups as bio-invasions that must be regulated-or somehow annihilated-during a period of American empire-building. Shinozuka shows how the modern fixation on foreign species provided a linguistic and conceptual arsenal for anti-immigration movements that gained ground in the early twentieth century. Xenophobia fed concerns about biodiversity, and in turn facilitated the implementation of plant quarantine measures while also valuing, and devaluing, certain species over others. The emergence and rise of economic entomology and plant pathology alongside public health and anti-immigration movements was not merely coincidental. Ultimately, what this book unearths is that the inhumane and unjust incarceration of Japanese Americans during World War II cannot, and should not, be disentangled from this longer history"--

Tiny ruby-throated hummingbirds weighing less than a nickel fly from the upper Midwest to Costa Rica every fall, crossing the six-hundred-mile Gulf of Mexico without a single stop. One of the many creatures that commute on the Mississippi Flyway as part of an annual migration, they pass along Chicago’s lakefront and through midwestern backyards on a path used by their species for millennia. This magnificent migrational dance takes place every year in Chicagoland, yet it is often missed by the region’s two-legged residents. The Art of Migration uncovers these extraordinary patterns that play out over the seasons. Readers are introduced to over two hundred of the birds and insects that traverse regions from the edge of Lake Superior to Lake Michigan and to the rivers that flow into the Mississippi. As the only artist in residence at the Field Museum, Peggy Macnamara has a unique vantage point for studying these patterns and capturing their distinctive traits. Her magnificent watercolor illustrations capture flocks, movement, and species-specific details. The illustrations are accompanied by text from museum staff and include details such as natural histories, notable features for identification, behavior, and how species have adapted to environmental changes. The book follows a gentle seasonal sequence and includes chapters on studying migration, artist’s notes on illustrating wildlife, and tips on the best ways to watch for birds and insects in the Chicago area. A perfect balance of science and art, The Art of Migration will prompt us to marvel anew at the remarkable spectacle going on around us.

A broad, multi-specific overview of the physiology, ecology, and evolution of migration, discussing and analysing migration across a full taxonomic range of organisms from primitive plants to classic migrants such as butterflies, whales, and birds.

This book basically involves the study of flight parameters, wing beat frequency, moment of inertia, and wing movements for developing various aerodynamic forces which have been calculated. The book is intended for biologists, physicists, nanotechnologists, and aerospace engineers. Resilin, an elastic polymer (4 λ) which is present at the base of insect, plays a major role in Neurogenic and Myogenic insect flyers and influences the physiology of flight muscles. Leading edge vortex (LEV) is a special feature of insect flight. Insect wings have stalling angle above 60 degrees as compared to a man-made aeroplane stalling angle which is 16 degree. Reynolds number, the knowledge of LEV, and detailed study of moment of inertia help in developing flapping flexible wings for micro-aerial-vehicles. This book serves as an interface between biologists and engineers interested to develop biomimicking micro-aerial-vehicles. The contents of this book is useful to researchers and professionals alike.
