Abstract
Faunistic and ecological surveys of medically important mosquito species of Japan were made by the author during the period from 1961 to 1966. A total of 5, 200 larval habitatsin 542 localities covering all the prefectures of Japan were surveyed, and altogether about 60 species were collected. The specimens were identified by mature larvae or by adults. The mosquito species were classified tentatively into 24 groups according to their taxonomic and ecological status, and the geographic distribution, type of larval habitats and the relation with associated species were discussed for each species or group. The results are summarized in Table 1 to 3.
