Abstract: 奄美大島において1972-1975年に蚊の調査を行なった.成虫は畜舎にかけたライトトラップ及び野外でのドライアイストラップにより,幼虫はその発生場所において,1年を通じて採集を行なった.その結果31種の蚊が得られた.上記の方法による採集の記録と,野外で採集した幼虫の飼育の記録とから,各々の種の,特に冬季における,生態について記載した.また,奄美大島での日本脳炎ウイルスの越冬について,伝搬蚊コガタアカイエカの生態の面から考察を加え,ウイルスの越冬が可能なのは,冬の気温が高く,蚊-豚の感染サイクルが持続する場合においてのみであると結論した. / Mosquitoes were investigated on Amami-Oshima Island in 1972-1975. Adults were collected by light traps at animal shelters and by dry ice traps in the field, and larvae at their breeding sites in the whole year. In total, 31 species of mosquitoes were found. From the mosquito catches by the above methods together with the rearing records of some larvae collected in the field, the biology of each mosquito particularly in the winter time was reported. Also, the possibility of the overwintering of Japanese encephalitis virus on Amami-Oshima was discussed on the basis of the biology of the vector mosquito, Culex tritaeniorhynchus. It was considered that the successful overwintering of the virus is attained only by the succession of the pig-mosquito cycle maintained by the continuous feeding activity of the vector mosquitoes in warm winter.
