Outline of Final Research Achievements

The oak longicorn beetle, Moechotypa diphysis, is a pest of the bed log for Shitake mushroom and an invasive species to Japanese main islands. I tried to create newly emerged mail adults of this species in spring, the original reproductive season, within the context of the development of sterile insect technique. I could have the newly emerged mail adults in spring by shortening the life cycle under warm temperate rearing or by the delaying under cool temperate rearing. I confirmed that the duration of sterility of the newly emerged mail was about one month by　microscopic observation and mating test.
