| Abstract: | Lygus lineolaris populations in the northeastern USA have been markedly reduced by the introduced parasitoid Peristenus digoneutis. A 3-year study in NJ where P. digoneutis has been established for many years demonstrated that parasitism of Lygus nymphs in strawberries averaged 30% (mostly P. digoneutis). Strawberry damage by L. lineolaris ranged from 19 to 33%. |
