title: Isolation of bovine arboviruses from Culicoides biting midges (Diptera: Ceratopogonidae) in southern Japan: 1985--2002.
abstract: In 1985--2002, surveillance for bovine arboviruses was conducted in Kagoshima, located in the most southern part of the main islands of Japan and known to be an area where bovine arboviral diseases have frequently been epidemic. Culicoides biting midges were collected in a cowshed by light traps. A total of 456,300 Culicoides biting midges representing 13 species were collected, and a portion of each pool of midges were tested for virus isolation. Overall, 85 isolates of six different viruses were obtained from the collected midges. The isolated viruses included two Orthobunyaviruses, Akabane and Aino viruses; three Orbiviruses, Chuzan, D'Aguliar, and Ibaraki viruses; and one unclassified virus, a bunyavirus-like virus. The viruses were most frequently isolated from Culicoides oxystoma Kieffer (85.9% of 85 isolates). Isolations of all viruses except for the bunyavirus-like virus were made from this species. Our data indicated that C. oxystoma is a potential vector for bovine arboviruses in southern Japan.
