This is the second year of a four-year USDA Risk Avoidance and Mitigation Program (RAMP) study being conducted in eight commercial peach orchards in southern New Jersey, USA. The main objective is to develop peach arthropod management programs that eliminate organophosphorus (OP), carbamate, and pyrethroid insecticide use. Targeted arthropods include: Conotrachelus nenuphar (Herbst), Platynota idaeusalis (Walker), Lygus lineolaris (Palisot de Beauvois), Grapholita molesta (Busck), Synanthedon exitiosa (Say), and S. pictipes (Grote & Robinson). Levels of male pheromone trap captures, shoot damage, fruit injury, and numbers of S. exitiosa and S. pictipes pupal exuviae from RAMP orchards were compared with levels observed from adjacent conventionally managed peach orchards that primarily used OP insecticides throughout the season.
Species 1: Lepidoptera Tortricidae Grapholita molesta (Oriental fruit moth)
Species 2: Coleoptera Curculionidae Conotrachelus nenuphar (Plum curculio)
Species 3: Heteroptera Miridae Lygus lineolaris (Tarnished plant bug)
