Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Spring Grain-Aphis or "Green Bug" In 1890, when the pest really first gave evidence of its capabilities as a grain destroyer over a wide range of country, the senior author again took up its study, gaining considerable additional knowledge of its habits and of the influences of temperature and Season upon its abundance. (see Diagrams I - V.) The less serious outbreak of 1901 was not investigated and our information relative to it is derived chiefly from correspondence of the bureau for that year. The incipient outbreak of 1903 was reported from Texas by Prof. E. D. Sanderson, at that time State entomologist, and from South Carolina by correspondents of the bureau.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is a comprehensive treatment of how the principles of ecology and conservation biology can be used to maximize biological control. Conservation Biological Control presents various means to modify or manipulate the environment to enhance the activities of natural enemies of pests. It establishes a conceptual link between ecology and the agricultural use of agents for biological control, and discusses both theoretical issues as well as practical management concerns. Certain to be interesting to ecologists and entomologists, this volume will also appeal to scientists, faculty, researchers and students interested in pest management, horticulture, plant sciences, and agriculture. - Contains chapters by an international team of leading authorities - Establishes a conceptual link between ecology and the agricultural use of agents for biological control - Discusses both theoretical issues as well as practical management concerns - Provides specific examples of how conservation principles are used to maximize the biological control of pests

Available in PDF, EPUB and Kindle. Book excerpt: Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.
