Culicoides populations have been monitored at 8 livestock premises in southern Alberta during the summers of 2002 and 2003. Culicoides sonorensis accounted for 7.7% (range 0 – 14.8%) of the total Culicoides captured during 2002, and 34.4 (range 0 – 59.6%) of the total captured during 2003. The major species of Culicoides captured, besides C. sonorensis, were C. gigas, C. crepuscularis, C. cockerelli, C. wisconsinensis, C. yukonensis, the Selfia group (contains C. denningi and C. jamesi), C. palmerae group (C. palmerae and C. davisi). C. obsoletus was collected rarely (3 specimens in 2002). None of these species, besides C. sonorensis, have been implicated as animal disease vectors in North America.
