| Outline of Final Research Achievements |
To elucidate the importance of evolutionary and genetic aspects of the Izu-Satsunan Islands from the viewpoint of insect resources, insect fauna was surveyed mainly focused on the following ecologically important taxa combined with molecular biogeographic studies: coleopteran superfamiles Curculionoidea and Scarabaeoidea, Hemiptera (true bugs) and gall-inducing insects. Many undescribed species including endemic ones were found particularly from the Satsunan Islands, and also both island areas were designated as distributional boundaries of many insect species. The Izu Islands becomes the eastern limit for many insects of the Ryukyuan element. The entire area of the Satsunan Islands from Kuroshima, Yakushima, Tanegashima to the Tokara Islands are regarded as a transitional zone of geographical distribution for many insects as the northern or southern limit so far as known. These facts suggest the importance of both island areas for biodiversity conservation and bioresource management.
