Excerpts from the report Summary: A comprehensive study was made at Tifton, Ga. , between 1952 and 1958 to determine the species of insects infesting stored farmers stock peanuts, their relative abundance, and the amount of damage they cause in typical commercial storages. Supplementary studies were made of peanuts stored in 500-bushel metal bins and in small experimental 5-cubic-foot bins. The studies were extended to cover infestation during harvesting. Several clear-cut findings relative to insect infestation and damage in farmers stock peanuts resulted from this study. Although the studies were confined for the most part to the area near Tifton, these findings will probably apply generally to all peanut-producing and storage areas in the United States
