【 摘 要 】

Abstract Plants emit herbivore-induced plant volatiles (HIPVs) in response to herbivory. Most of the previously reported studies on the ecological function of HIPVs focused on a single tritrophic system in which one herbivores of one species attacked an individual plant. However, in nature, plants are in general attacked by multiple herbivore species. In this study, we focused on a plant infested by two herbivore species. This study showed that the attractiveness to Cotesia vestalis of the cabbage plants infested by both host and non-host is affected by the density and developmental stage of non-hosts. This could be explained by the changes in the blend of host-induced volatiles that attract C. vestalis due to the effects of the damage caused by the non-hosts. Further chemical studies will be needed to identify the factors affecting the attractiveness of both infested plants.
