Insects as a group occupy a middle ground in the biosphere between bac at one extreme, amphibians and mammals at the other. teria and viruses of insects present special problems to the The size and general nature study of entomology. For example, many commercially available instru ments are geared to measure in grams, while the forces commonly en countered in studying insects are in the milligram range. Therefore, tech niques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just ofthese techniques find their way into the classroom when as often, some the problems involved have been sufficiently ironed out to permit students to master the manipulations in a few laboratory periods. Many specialized techniques are confined to one specific research lab oratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save con siderable time. It is the purpose of this series (1) to report new devel opments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which may be applicable for use in biology laboratory courses."

Contributed papers by experts in the field detail how to put integrated pest management to work. Presents the philosophy and practice, ecological and economic background as well as strategies and techniques including not only the use of chemical pesticides but also biological, genetic and cultural methods to manage the harm done by insect pests. Covers such key crops as cotton, corn, apples and forage. This edition reports important advances of the last decade including an increased environmental and ecological awareness and a trend toward lower chemical pesticide use.
