Abstract

To identify the vectors of bluetongue virus (BTV) in Germany, we monitored Culicoides spp. biting midges during April 2007-May 2008. Molecular characterization of batches of midges that tested positive for BTV suggests C. obsoletus sensu stricto as a relevant vector of bluetongue disease in central Europe.

Monthly catches of midges of the Culicoides obsoletus group (black), C. pulicaris group (red), and other Culicoides spp. (blue) captured with 89 black light traps in Germany during 7 consecutive nights in the first week of each month during the study period (April 2007–May 2008). Batches consisting of <50 female biting midges were tested for bluetongue virus (BTV) by real-time reverse transcription–PCR. The total number of batches (green) and the number of batches positive for BTV (gold) are shown.
