Outline of Final Research Achievements

Floating insects in the atmosphere were observed and analyzed using the high-sensitivity millimeter-wave radar “FALCON-I”. Floating objects distributed up to 1.5 km height in clear days, with its number density of several per 103 m3, but in winter it reduced in 1/5 of that. Sizes of insects trapped with a tethering balloon at the height of around 300m are 0.4 to 2 mm. Comparing with the observation of echoes with FALCON-I these sizes of insects can be detected with this facility.

Academic Significance and Societal Importance of the Research Achievements

大きさが1mm 程度の大気浮遊昆虫をリ モートセンシングで一匹一匹捉え解析したのは一連の本研究が世界初である。ウンカやクモ類であるハダニなど 1-2mm の虫は、移動特性などが解明されておらず、本研究は飛来害虫の監視や昆虫の生態研究を変革する可能性があり、学術的・社会的意義が大きい。本研究をもとに、日本の重要な輸出産品になりつつあるコメや果物などの農産物の安全性がさらに高まるなど、波及効果が期待できる。
