Outline of Final Research Achievements

In this study, we evaluated the adaptability of existing materials (artificial diet) so that we can quickly respond to the new invasion of wood-destroying beetles due to the globalization of logistics. As a result, it was found that Lyctoxylon dentatum and Ptilineurus marmoratus can also be reared by the same diet. In addition, we examined the mass rearing method, which is indispensable for devising a control method, and confirmed the life cycle of Nicobium hirtum and Heterobostrychus aequalis, which is a minor but has already damaged cultural properties.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により、既にある材料（ヒラタキクイムシ用人工飼料）は、ヒラタキクイムシ類、シバンムシ類、シンクイムシ類等、多種甲虫類の飼育に利用できると考えられた。被害発見が遅れがちな木材食害性甲虫類の侵入種が国内で発見されたとしても、速やかに飼育でき防除法を検討する一助となりうる。
