| Outline of Final Research Achievements |
Shimada, Shibao and Matsuyama analyzed and synthesized kairomones when the parasitoid wasp Anisopteromalus calandrae searched the two species of Callosobruchus seed beetles. We collected and extracted footprint chemical substances of each seed beetle, and determined their chemical structures using GC-MS. Kairomones of C. chinensis were mainly 11-MeC27, and most of C. maculatus were 9-MeC27、3-MeC29、9,13-diMeC29. When we synthesized the four substances and provided wasps them, we could induce wasps parasitizing behaviors and memories with learning the substances. Shimada and Sasakawa examined effects of different host developmental stages (the pupae and the final instar larvae of C. chinensis and C. maculatus) on learning behavior of parasitizing in Heterospilus prosopidis. We discovered (1) they could learn the pupae but not the larval stage, (2) they could not find the larval stage with memories of the pupae they had learned.
