| Outline of Final Research Achievements |
The parasitic wasp, Cotesia vestalis, oviposits on larvae of the diamondback moth, Plutella xylostella, a pest of Brassicaceae plants. It has been known that the female parasitoids search for host larvae through volatile compounds released from host-infested plants. In this research, aromatic and terpenoid compounds from flowers were newly elucidated as cues for the parasitoids to search for floral food. And, it was demonstrated that the females can use different cues to search for food and hosts depending on their dietary status. These results has provided us new information on ecological role of flowers in biological interactions, and such information would be helpful in designing effective pest management systems using natural enemy wasps.
