| Outline of Final Research Achievements |
Ant plant Macaranga has a close interaction with various symbionts (ants and scale insects) and parasites (butterflies, bugs, gall midges, and stick insects). In this study, the hypothesis that the species diversity of this system has been brought about by the co-evolution between parasites and symbionts was verified by using phylogenetic analyses of the 7 parties. It was shown that the ant-plant symbiosis was founded about 20 million years ago, and then the other members of the system sequentially took part in the system. Additionally, the species specificities among the parasites and the symbionts proved to be high. These results suggest that the counter adaptation and co-evolution among parasites and symbionts promoted the diversification of the overall system.
