In order to determine the olfactory-behavioral mechanisms underlying the host-finding of Cydia zebeana and to explore environmentally sound IPM control methods, the behavioral responses of C. zebeana adults (virgin females and males) and its two parasitic wasps, Ascogaster olethreuti and Macrocentrus sp. to different concentrations of nine larch volatiles (Larix gmelinii, both bark and needle volatiles) were tested in the laboratory using Y-tube olfactomter. The results showed that females of C. zebeana were significantly attracted to (+)-3-carene and (R)-(-)-α-phellandrene, and were strongly repelled by myrcene, ocimene, and camphene. (R)-α-pinene was attractive at low concentrations, but repellent at high concentrations. In contrast, C. zebeana males were attracted to (S)-β-pinene, and repelled by myrcene, (+)-3-carene, (S)-α-pinene and camphene. A. olethreuti adults were attracted to (S)-β-pinene, (S)-α-pinene and phytol, while they were repelled by ocimene, camphene, and (R)-(-)-α-phellandrene. Macrocentrus sp. were attracted to (S)-β-pinene, (S)-α-pinene, phytol and (R)-α-pinene. They were also repelled by ocimene and (R)-(-)-α-phellandrene. As a part of push-pull control strategies against C. zebeana, myrcene, phytol, and (S)-α-pinene can be applied to the target forests to repel the moths, and to attract their parasitoid wasps, whereas (R)-(-)-α-phellandrene can be applied to the bait trees in combination with insecticide sprays to attract the moths and to repel parasitoid wasps.
