Establishment of the mass culture of wood-attacking anobium beetles

该项目的目的是建立攻木厌氧菌甲虫的大众文化，厌氧菌甲虫是日本木制文化材料中最重要的害虫。此外，我们尝试制定木质文化建筑中蛀木昆虫的监测方案，并对老化木材的生物和化学特性进行研究。虽然目前Nicobium的群体培养尚未实现，但我们已经成功地建立了以Lyctus beetles人工饲料为食的异胸蝇（Heterobostrychus aequalis）实验室群体培养。这是在日本的第一次成功。人们强烈期望在未来进行大规模养殖昆虫的生态学研究。对老化松材的抗白蚁和抗真菌性能进行了调查，并结合化学分析。结果表明，部分提取物经老化转化为氧化态，具有较高的抗生物降解活性。

The purpose of the project was to establish the mass culture of wood-attacking anobium beetles, which are the most important pests for wooden cultural materials in Japan. In addition, we tried to develop the monitoring protocols regarding wood-attacking insects in wooden cultural buildings together with a research on biological and chemical characteristics of aged wood.Though the mass culture of Nicobium species has not been obtained yet, but we have succeeded in establishing the laboratory mass culture of Heterobostrychus aequalis with the artificial diet of Lyctus beetles. This is the first success in Japan. Future ecological studies with mass cultured insects are strongly expected.The aged pine timbers were surveyed for their anti-termite and anti-fungal performance in combination with the cheimical analyses. The results suggested that some extractives were converted into the oxidized forms by the aging, and they had higher anti-biodegradation activities.
