The oriental fruit moth (OFM), Grapholita molesta Busck, is a major internal feeding pest of apples and peaches in the eastern United States. While OFM has historically been a major peach pest, recent outbreaks on apple have resulted in substantial economic losses due to OFM feeding damage in fruit. Important biological differences exist between OFM that develop on peach versus those in apple. Several studies were set out to determine how the host plant affects the ovipositional behavior of OFM. Paired tree choice bioassays showed that OFM adults prefer to oviposit on peach trees over apple trees for much of the season. Field level examination of oviposition behavior confirms these findings, but also indicates that apple fruit serve as a suitable egg laying site. Changes in oviposition behavior are impacted by cultivar and the progression of the growing season. Results from seasonal orchard experiments and implications for integrated management of OFM are discussed.
