| Outline of Final Research Achievements |
In many cases, parasitic wasps are attracted to host herbivore-infested plant odors. We focused on Cotesia vestalis, a parasitic wasp of diamondback moth larvae, and three crucifer plant species (cabbage, komatsuna and Japanese radish). We examined how the wasp responded to host-infested plant volatiles (HIPVs) of either the same or different plant species when the wasp has experienced HIPVs from one plant species. HIPVs from each plant species differently affected the wasp’s subsequent responses to HIPVs.
We also investigated genetic variation among local populations of C. glomerata, a parasitic wasp of cabbage white butterfly larvae throughout Japan. Bayesian cluster analysis revealed two or three genetic clusters across the locations sampled. The pattern of genetic differentiation, estimated from the microsatellite data, indicated a significant level of difference in genetic structure between Hokkaido populations and other populations.
