| Outline of Final Research Achievements |
In this study, the mechanism of suppressing occurrence of Psychodidae by sediment microbial fuel cells was elucidated. The results revealed that metal components included in sewage sludge were ionized and released with generating electricity by sediment microbial fuel cells. Since it was found that some of metal components affect hatching process of Psychodidae, the phenomenon of suppressing occurrence of Psychodidae is likely caused by metal release from sewage sludge used for fuel in sediment microbial fuel cells. This phenomenon would be applicable at environment where Psychodidae spawns and metal release with generating electricity by sediment microbial fuel cells occurs.

| Academic Significance and Societal Importance of the Research Achievements |
堆積物微生物燃料電池をチョウバエのような害虫の抑制に活用した事例はなく、ミリボルトレベルの微弱な電気で害虫を抑制する手法の報告例も見当たらない。本研究成果は、微生物燃料電池の応用性を広げ、薬剤に頼らない新しい害虫抑制手法の可能性を提案するものであり、下水汚泥に限らず有機物と金属を含有する様々な環境において薬剤を使用せずに害虫を抑制する可能性を明らかにした点に意義がある。
