An insect catcher with a biofuel cell structure, which comprises a housing in communication with an insect catching cover, the housing is defined with a receiving groove for receiving an anode electrode and an annular groove for receiving a cathode electrode. The insect catching cover is defined with a plurality of single entries for the entrance of mosquitos and flies, and a light-emitting unit is disposed in the insect catching cover and is electrically connected to the anode and cathode electrodes. Thereby, the caught insects used as the source of organic compounds for driving the biofuel cell to produce electricity, forming the insect catcher capable of self-generating electricity, which can solve the electricity-supplying problem for outdoor use.本發明提供一種具生物燃料電池結構之捕蟲器,其主要包括內部相連通之基殼及捕蟲罩,該基殼內部成形有供設置陽極電極與陰極電極之容槽及環槽,該捕蟲罩開設有複數單向入口供蚊蠅進入,令一發光單元設於該捕蟲罩內並與該陽、陰極電極電性連接,藉此,本發明利用捕蟲器所捕捉之蟲體作為驅動生物燃料電池產生電力的有機物來源,以進一步有效利用被捕捉之蟲體,同時形成自體產生電力之捕蟲器,達到解決捕蟲器於室外環境使用之電力供應問題。20‧‧‧基殼201‧‧‧頂部202‧‧‧底部21‧‧‧殼件22‧‧‧蓋件23‧‧‧組設口24‧‧‧容槽241‧‧‧含菌溶液25‧‧‧通透膜26‧‧‧環槽261‧‧‧還原溶液30‧‧‧捕蟲罩301‧‧‧頂部302‧‧‧底部31‧‧‧空間32‧‧‧集中出口33‧‧‧透光孔34‧‧‧單向入口340‧‧‧擋片341‧‧‧尖部342‧‧‧十字孔40‧‧‧陽極電極50‧‧‧陰極電極60‧‧‧發光單元
