Summary: The objectives of this project were: 1. Develop economic thresholds for Lygus on apples. 2. Evaluate cover crops/ indigenous plants for their ability to increase survivorship/ effectiveness of Lygus parasitoids. 3. Survey conventional and organic apple orchards for the presence of Lygus parasitoids. 4. Conduct innoculative releases of Peristenus spp. into established refugia in apple growing regions where Peristenus has not been detected. 5. Conduct orchard floor treatments with formetanate hydrochloride and several candidate synthetic pyrethroid insecticides
