Our Reduced Risk peach arthropod management program integrates mating disruption to control Oriental fruit moth and greater and lesser peach tree borers with reduced risk insecticides to control various pests including plum curculio, catfacing insects, tufted apple both moth, mites, and aphids. Changes in pest numbers and levels of fruit damage were evaluated during the first three years of this study and compared with levels in adjacent orchards sprayed predominantly with organophosphorus, carbamate, and pyrethroid insecticides. Levels of beneficial fauna abundance were also compared.


Species 1: Lepidoptera Tortricidae Grapholita molesta (Oriental fruit moth)
Species 2: Heteroptera Miridae Lygus lineolaris (tarnished plant bug)
Species 3: Lepidoptera Tortricidae Platynota idaeusalis (tufted apple bud moth)
Keywords: mating disruption, peach orchards
