N2 - We investigated whether or not pear ester (ethyl (E,Z)-2,4-decadienoate) attracted adult oriental fruit moths, Cydia molesta (Busck) (Lepidoptera: Tortricidae). The electroantennographic
responses of C. molesta to pear ester were recorded and dose2response curves
calculated. In laboratory bioassays, the attractiveness of different dosages was assessed in a dual-choice olfactometric arena. The responses of virgin males and females to pear ester in the presence and absence of pear (Pyrus communis L.), peach (Prunus persica (L.) Batsch.), and apple (Malus 6domestica Borkh.) (Rosaceae) shoots were evaluated. Electroantennographic
recordings demonstrated that both male and female C. molesta were able to detect the pear ester. In our bioassay, however, pear ester readily attracted males but attracted very few females. The response of males was dose-dependent and they preferred pear ester over apple and pear-shoot volatiles, whereas no apparent preference between pear ester and peach-shoot volatiles was observed. Therefore, this kairomonal compound could be more effective in attracting C. molesta when applied in orchards of secondary host plants, like apple or pear, than in peach orchards.
