Peristenus digoneutis (Hymenoptera: Braconidae) was successfully established in the northeastern United States in the 1980ís for biological control of the tarnished plant bug, Lygus lineolaris. P. digoneutis attacks nymphs and in alfalfa generally exceeds levels of parasitism by native parasitoids. P. digoneutis expanded its geographic range and spread from the alfalfa fields to strawberries, a high value crop. We report here that P. digoneutis and two native parasitoids, P. pallipes and P. pseudopallipes are also present in New York apple orchards. In addition, we report parasitoid success under different insecticide treatments: conventional, reduced risk, organic and unsprayed (abandoned) apple orchards.
