Farm Friends and Farm Foes


Book Description

Excerpt from Farm Friends and Farm Foes: A Text-Book of Agricultural Science This book is intended to serve as a text and guide for the study of those plants and animals so vitally related to crop production as often to determine success or failure therein. The information given embodies the latest re searches of that host of investigators who have done such great service in the advancement of agriculture in recent years. The text has been so combined with directions for observation and expression that it is hoped that teachers will be able to lead their pupils to a first-hand knowledge of the most important plants, insects, birds, and mammals to be found in the region of the school. Most of the original engravings are from drawings by Mr. W. I. Beecroft, a few being adapted from the publica tions of authors to whom credit is given in the list of illus trations.' Many of the insect pictures are from woodcuts originally made for the classic report on [meets [njun'ous to Vegetation, by Dr. T. W. Harris, for the use of which thanks are returned to Mr. J. Lewis Ellsworth, Secretary of the Massachusetts State Board of Agriculture. For courtesies in connection with other illustrations I am in debted to Misses Hazel Dearth, Alice Manning, and I. S. Cragin, and Messrs. James Hall, A. G. Randall, E. D. San derson, A. D. Selby, A. H. Verrill, and C. W. Woodworth, as well as to the Experiment Stations of Illinois and New Hampshire and the United States Department of Agri culture. I have also to thank Mr. W. F. Fiske, of the Gypsy Moth Laboratory, for kindly reading the proof of the chapters on Predaceous and Parasitic Insects.

Ecologically Based Pest Management


Book Description

Widespread use of broad-spectrum chemical pesticides has revolutionized pest management. But there is growing concern about environmental contamination and human health risksâ€"and continuing frustration over the ability of pests to develop resistance to pesticides. In Ecologically Based Pest Management, an expert committee advocates the sweeping adoption of ecologically based pest management (EBPM) that promotes both agricultural productivity and a balanced ecosystem. This volume offers a vision and strategies for creating a solid, comprehensive knowledge base to support a pest management system that incorporates ecosystem processes supplemented by a continuum of inputsâ€"biological organisms, products, cultivars, and cultural controls. The result will be safe, profitable, and durable pest management strategies. The book evaluates the feasibility of EBPM and examines how best to move beyond optimal examples into the mainstream of agriculture. The committee stresses the need for information, identifies research priorities in the biological as well as socioeconomic realm, and suggests institutional structures for a multidisciplinary research effort. Ecologically Based Pest Management addresses risk assessment, risk management, and public oversight of EBPM. The volume also overviews the history of pest managementâ€"from the use of sulfur compounds in 1000 B.C. to the emergence of transgenic technology. Ecologically Based Pest Management will be vitally important to the agrichemical industry; policymakers, regulators, and scientists in agriculture and forestry; biologists, researchers, and environmental advocates; and interested growers.




Agricultural Entomology


Book Description

Agricultural Entomology presents a global view of the insect groups that are of major significance to human resources. "Agriculture" in this broad sense includes plants grown for food, horticultural field crops, and other ornamentals. Information is also included on insect pests of stored products, forest resources, and livestock, although in less detail. The book is intended for use as a college text and reference and assumes a basic knowledge of entomology but is also of great value outside the classroom for its comprehensive and detailed approach. There is a chapter on beneficial insects, including pollinators, honeybees, silkworms, and insects from which shellac and cochineal are made. Hundreds of high-quality line drawings and black-and-white photographs illustrate the insects, and an illustrated glossary and indexes of scientific and common names are provided. Almost all countries of the world are undergoing agricultural diversification programs with the introduction of new and exotic crops. Yet most books on insect pests restrict coverage to one country or region or to the tropics or temperate zones. The global approach of Agricultural Entomology emphasizes the similarities and important differences between insect pests of the major continents. It thus brings attention to insect species that might well spread as pests to new geographical areas. Closely related species are also treated, highlighting problems of control that could result from unsubstantiated identifications. Agricultural Entomology is a valuable resource for growers and gardeners interested in the developing field of integrated pest management. With copious information on the biology of insects around the globe, this authoritative and comprehensive book is an essential tool for anyone interested in understanding both the foes and allies of the insect world.
