Outline of Final Research Achievements

The ambrosia beetle Platypus quercivorus causes mass mortality of oak trees, Japanese oak wilt, by transporting a pathogenic fungus from trees to trees. Using a flight mill to simulate insect flight in a room, we showed that there are sexual differences in the flight ecology of the beetle, and elucidated the causes of the large variation in its flight distance. Two-choice tests of host and non-host tree saplings showed that the beetle is attracted to volatiles from the canopy of host trees and avoid volatiles from the canopy of non-host trees. It was clarified that the beetle bores into narrow-angled crevices regardless of the type of wood, and that this behavior is activated after flight. Long-term forest dynamics studies in natural and secondary forests clearly showed the effects of Japanese oak wilt, including a decrease in species diversity.

Academic Significance and Societal Importance of the Research Achievements

広大な森林において微小なキクイムシの生態を捉えることは難しい。その飛翔生態や溝への穿孔行動を室内実験で詳細に明らかにしたことは、森林昆虫学の発展に寄与する成果であると同時に、防除計画の立案や防除資材の開発に役立つ成果でもある。カシノナガキクイムシが寄主の樹冠からの揮発性物質を寄主探索に利用していることが示唆されたが、これは野外での誘引トラップの設置方法を再考する必要があることを示している。エネルギー革命に伴う薪炭林の放置が近年の急速なナラ枯れ被害拡大の一因と指摘されている。ナラ枯れが長期森林動態に大きな影響を及ぼしていることが示唆されたが、これは人間の森林利用様式の再考を促す研究成果である。
