Abstract
Surveys have been repeatedly conducted on rickettsia harbering rodents and medically important arthropods on three islands, Koshiki, Tane and Yaku, Kagoshima Prefecture, the most southern part of Japan, in May, 1959 and February, 1960. The results obtained so far in species and number of trombiculid mites and other medically important insects such as mosquitoes and flies are briefly summarized in the tables. This investigation was supported in part through a grant under contract No. DA-92-557-FEC 31, 515 between Dr. Takeo Tamiya and Offics of the Sugeon General U.S.A.
