| Research Abstract |
To test the hypothesis of sequential speciation, the present study focused on parasitoid wasps of a leaf-mining moth, Acrocercops transecta (Gracillariidae), which consists of host races between Juglandaceae and Ericaceae plants. I assessed the genetic diversity between parasitoid wasps emerged from the Juglandaceae race and from the Ericaceae race and compared the structure of parasitoid communities of the two host races. A phylogenetic study using mitochondrial COI gene did not distinguish the parasitoids from the two host races. However, the parasitoid communities are clearly distinct between the two host races, indicating that host plants play an important role in the host selection of parasitoid wasps.
