Augmentation of Natural Enemies for Control of Plant Pests in the Western Hemisphere

Part of the Environmental Science Research book series (ESRH, volume 11)

Abstract

Augmentation is defined as periodically increasing either the number of parasites or predators or the supply of their food resources to assure that adequate numbers of parasites and predators are present to provide the desired level of pest control. Similar definitions have been used previously (Ridgway 1972, Rabb et al. 1976). The release of natural enemies has also been classified as being either inoculative or inundative (DeBach and Hagen 1964). Inoculative releases appropriately describe releases of natural enemies for the purpose of colonizing populations to regulate pest populations through in-field reproduction of the released species. However, the use of inundative releases to describe all other augmentative releases may be misleading since by definition inundative means “to flood or to overwhelm by great numbers.”
