Healthy Crops


Book Description

This work powerfully asserts the idea that rather than using pesticides, the key to helping crops resist attacks from pests is to improve their strength through natural processes. Many of industrial agriculture's fundamental principles for fighting disease, in particular the reliance on pesticides and fertilizers, are explained and convincingly challenged and a new set of guiding principles for an ecological agricultural system are presented as a genuine alternative to the widespread use of chemicals.







Regulatory Mechanisms in Insect Feeding


Book Description

The only book to deal comprehensively with insect feeding was published by C. T. Brues in 1946. His Insect Dietary was an account of insect feeding habits. Since that time there has been a revolution in biology, and almost all aspects of our understanding of insect feeding have expanded to an extent and into areas that would have been unthinkable in Brues' day. Yet, our book does not replace Insect Dietary but, instead, complements it, because our aim is to bring together information on the mechanisms by which food quality and quantity are regulated. We deliberately focus attention on the feeding process; to include food-finding would have required a much larger book and would have moved the focus away from more proximate mechanisms. This book is dedicated to the late Vincent G. Dethier. As a pioneer in studying the physiological basis of animal behavior, he focused on regulation of feeding in flies and caterpillars. His work on the blowfly, together with that by his many students and co-workers, still provides the most completely described mechanism of insect feeding. The citation of his work in almost every chapter in this book illustrates the importance of his findings and ideas to our current understanding of regulation of insect feeding. The authors in this book provide many innovative and stimulating ideas typifying Dethier's approach to the study of feeding be havior.

Edible Insects


Book Description

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.







Insects and Gardens


Book Description

It might be time to declare a truce with the insects in our lives. With a sound basis in science and a practical grounding in gardening experience, Grissell introduces the reader to the role of insects in garden ecology. Illustrated with gorgeous photographs and now available in paperback, this book will be loved by anyone seeking a greater appreciation and understanding of these often-maligned garden visitors.




For Love of Insects


Book Description

Imagine beetles ejecting defensive sprays as hot as boiling water; female moths holding their mates for ransom; caterpillars disguising themselves as flowers by fastening petals to their bodies; termites emitting a viscous glue to rally fellow soldiers--and you will have entered an insect world once beyond imagining, a world observed and described down to its tiniest astonishing detail by Thomas Eisner. The story of a lifetime of such minute explorations, For Love of Insects celebrates the small creatures that have emerged triumphant on the planet, the beneficiaries of extraordinary evolutionary inventiveness and unparalleled reproductive capacity. To understand the success of insects is to appreciate our own shortcomings, Eisner tells us, but never has a reckoning been such a pleasure. Recounting exploits and discoveries in his lab at Cornell and in the field in Uruguay, Australia, Panama, Europe, and North America, Eisner time and again demonstrates how inquiry into the survival strategies of an insect leads to clarifications beyond the expected; insects are revealed as masters of achievement, forms of life worthy of study and respect from even the most recalcitrant entomophobe. Filled with descriptions of his ingenious experiments and illustrated with photographs unmatched for their combination of scientific content and delicate beauty, Eisner's book makes readers participants in the grand adventure of discovery on a scale infinitesimally small, and infinitely surprising.







Aphid Ecology An optimization approach


Book Description

This second edition covers the evolution of aphids and their development in relation to specific plants, thoroughly revised and expanded since the first highly successful edition. Increasing knowledge of aphids has revealed that they are ideal organisms to use when studying many topical ecological issues.
