The increase has mainly been in processing peaches. Most of these plantings are interplanted near apple and pear orchards. The Oriental fruit moth (OFM) larva is an internal fruit pest of peaches, apples, and pear, and it feeds on shoots of peaches and apples. Two factors may be contributing to the increase in pressure from this pest: 1) OFM is less susceptible to the current pesticides used and 2) many apple growers are reduce the use of OP’s and other broad-spectrum insecticides in apples. Mating disruption (MD) was implemented in 210 acres of peaches using Isomate M100 twist ties. The principle behind MD is to flood the orchard with the sex attractant pheromone naturally exuded by the female OFM to attract the male. The males are not able to locate the female moths with the saturation of the orchard and so mating is prevented. Orchards under MD were compared to orchards under conventional insecticide management.en-USAgricultural IPMApplesFruitsTree FruitPeaches and NectarinesBiocontrolreport
