Book Description
Handbook of Soybean Insect Pests is the first book in a new series from the Entomological Society of America that examines pest management from all angles—magnifying practical field strategies for growers—and updates growers on the latest protection techniques—preventing needless crop loss as a result of outdated pest control procedures. Edited by Leon G. Higley and David J. Boethel, this book outlines fundamental approaches to soybean pest management that can aid in reducing crop damage and loss. It provides detailed descriptions of topics such as insect identification, life-history data, and management options. This comprehensive guide includes discussions on soybean ecology and physiology, soybean insect pests, predators and parasitoids, soybean pest management procedures, noninsect soybean pests, and insect management. Also included are 92 color photographs, 200 illustrations, a directory of resources for obtaining local information, and a glossary.

Book Description
Large screen cages were used to confine varying populations of bean leaf beetles, Cerotoma trifurcata (Forster), on soybean plants, Glycine max (L.) Merrill, in order to study the effects of larval feeding on nodulation and nitrogen fixation. The study was conducted during the summers of 1978, using 5 treatment levels, and 1979, using 4 treatment levels. Mean season-long populations ranging from 0.38 to 2.62 adults per sweep caused significant (P 0.05) amounts of nodule demage. Nodule quality, as determined by number and total dry mass of nodules per plant, was adversely affected by larval feeding in all infested treatments in 1979, but appeared unaffected in 1978. However, contamination of the control at about the middle of the 1978 growing season somewhatconfounded that year's dat. Nitrogen fixing capacty of plants in infested treatments was significantly reduced (P 0.05) for both years and averaged only ca. 55% of the rate of control plants according to results of acetylene-ethylene reduction assays. Yield was not significantly (P 0.05) influenced by this reduction in nitrog fixing ability.
