Outline of Final Research Achievements

Why are symbiont polymorphisms of stinkbugs found only in the Nansei islands but not in the Japanese main lands. This study tested the hypothesis that there is the environmental symbiont pool in the Nansei islands but not in the Japanese main lands. Results of the experiments favored the hypothesis. This study sheds light on a new aspect of the biodiversity in the Nansei Islands.
