In 2 permanent suction light trapping stations at Bet-Dagan and Kabri designated to monitor bluetongue virus (BTV) activity, 12 isolations were made during 1981 to 1983 from C. imicola. Isolation attempts from C. obsoletus, which was dominant in Kabri and caught concurrently with C. imicola did not yield BTV, while isolations were made from C. imicola. Negative isolation atempts were also experienced in C. oxystoma, C. puncticollis and C. circumscriptus, while BTV was isolated from C. imicola. So far the following serotypes of BTV were isolated from Culicoides spp. in Israel: 2, 4, 6, 10 and 16. |
