Two commercial warehouses containing farmers stock peanuts were used to demonstrate ability ofBracon hebetorSay (Hymenoptera: Braconidae) andXylocorts flavipes(Reuter) (Hemiptera: Anthocoridae) to suppress field populations ofCadra cautella(Walker) (Lepidoptera: Pyralidae) andPlodta interpunctella(Hübner) (Lepidoptera: Pyralidae). One warehouse (treatment) containing peanuts with only traces of malathion residues received periodic releases ofB. hebetorandX. flavipesthroughout the storage period from 5 October 1983 to 3 January 1984. The control warehouse received no natural enemies but contained peanuts conventionally treated with malathion. Moth populations in the treatment warehouse were 54–83% smaller than populations in the control warehouse throughout the storage period. Also, peanuts in the treatment warehouse sustained less insect damage during the storage period. Approximately 324,000B. hebetorand 191,000X. flavipeswere released.
