This is the first of a series of reports based on a sampling of insects on Arizona crops, begun under University of Arizona Experiment Station Project 302 (Arizona Insects of Economic Importance) and continued under Hatch Project 404 (Insect Parasites and Predators of Insect Pests of Arizona Crops). The series will summarize the information gained in the sampling as it relates to parasitic and predaceous insects, with a summary of the pertinent literature on these insects.
