Outline of Final Research Achievements

We studied on life type, life history, behavior and molecular phylogeny of the genera, Stigmaeopsis and Schizotetranychus. Stigmaeopsis longus on Sasa senanensis is different from that on Sasa kuriensis, because there is a reproductive isolation between them. Furthermore, we found out a new criptic species which occurrs on Pleioblastus sp. As a whole, we attempted to conclude the biology of 10 Stigmaeopsis species being distributed in China and Japan, and learned that the adaptive radiation in Stigmaeops must be mainly caused by predation pressure. Stigmaeopsis had been belonged to Schizotetranychus which is one of the big genera in Tetranychidae, but now it was known to be independent genus far from Schizotetranychus. Thus present study strongly suggested that we must thoroughly changed the sytematics of Tetranychidae.
