Knowing and Recognizing:
The Biology of Glasshouse Pests and Their Natural Enemies

Koppert Biological Systems of the Netherlands, a biological pest management company, has published this 109-page book by M. Malais and W. J. Ravensberg to assist growers, suppliers, advisors, educators, and others involved in greenhouse production. They indicate that a knowledge of the pest organisms and their natural enemies is essential to the success of any biological control program in greenhouses. Brief, but good, basic information is provided on the life cycle, appearance, development time, reproduction, damage and crop infestation patterns of spider mites, whiteflies, thrips, leafminers, aphids, mealybugs, butterflies and moths, vine weevils, shore flies, and other miscellaneous insect pests. Excellent photographs and diagrams of pest life cycles accompany each section.

For each pest, the major commercially-available natural enemies are examined in detail. Once again, life cycle, appearance, development time, and reproduction are discussed for each, as well as searching behavior and distribution, and the feeding behavior of predators. Development times at various common greenhouse temperatures are included in convenient charts for many insects, and other charts highlight important considerations in pest or natural enemy performance.

A glossary is included and the scientific publications used in the preparation of the book are referenced at the end.

Entomopathogenic Nematodes in Biological Control

This 365-page treatise on insect-infecting nematodes and their associated bacteria, edited by Randy Gaugler and Harry Kaya (CRC Press, 1990), is intended to serve as a comprehensive resource for those entering the field. Twenty-five authorities from around the world contribute chapters on basic and applied concepts, with diverse topics ranging from biological control theory to organismal and molecular biology. Basic information on nematode and bacterial biology is included, as well as discussions of anticipated new directions in pest control.

Food, Crop Pests, and the Environment

This book is a compilation of reports prepared by committee workgroups in support of a National Integrated Pest Management Forum held in Washington, D. C. in 1992 that addressed the need and potential for biologically intensive integrated pest management in agroecosystems. Four chapters describe the then-current status of IPM in several different commodities (corn/soybean, cotton, tree fruits apple is the example crop, and vegetable crops potato and tomato used for examples) from a national perspective and predict what advances in pest managment could be expected with additional research. The emphasis is on nonpesticidal tactics, which includes cultural controls and host plant resistance/biotechnology in addition to biological control, and all pests are considered, not just insects. The major constraints to the implementation of IPM, as identified by the committees dealing with specific commodities, are categorized and presented in the final chapter. Edited by F. G. Zalom and W. E. Fry (APS Press, 1992), 179 pages.
