説明

Although 14 species of mosquitoes were collected in Che-ju Island, Korea in August and September, 1970-1972, dominant mosquitoes feeding on man around dwelling houses were Culex pipiens pallens and Aedes togoi. Natural infections with infective larvae of Brugia malayi were demonstrated only in Ae. togoi. It is considered from these facts that the main vector of malayan filariasis in Che-ju Island is Ae. togoi. Anopheles sinensis which is known as the vector of malayan filariasis in other areas does not seem to act an important role in the transmission in Che-ju Island, because the desnity is very low owing to the scarcity of suitable breeding places. The period for the larvae of Brugia malayi to mature in Ae. togoi was estimated to be between 6 and 9 days from the results obtained by dissecting the females of the mosquito reared in the laboratory for various days after the collection at houses with microfilarial carriers. This period is much shorter than in the case of Wuchereria bancrofti. The breeding of Ae. togoi was observed mainly in rock pools on the seacoast, and only very rarely in artificial water containers within villages. Generally, adult females of this mosquito were abundantly found at houses near to the seacoast, and the density decreased with the distance from the seacoast. Similar tendency was seen in the distribution of the patients of malayan filariasis.
