| Research Abstract |
The parasitic wasp, Cotesia vestalis, oviposits on larvae of the diamondback moth, Plutella xylostella, a pest of Brassicaceae plants. It is known that the female parasitoids search for host larvae through volatile organic compounds(VOCs) released by host-infested plants. To investigate molecular basis of mechanisms underlying VOC-mediated tritrophic interactions among Brassicaceae plants, herbivores, and parasitoids, we carried out chemical analysis of VOCs released by Arabidopsis thaliana infested by P. xylostella larvae, then genetically manipulated the VOC biosynthesis in Arabidopsis plants, and examined behavioral responses of parasitoids to the transgenic plants.
