Abstract

Background In Senegal, the 2007 epidemic of African horse sickness (AHS) caused the death of 1,169 horses and considerable economic loss (Akakpo et al. 2011). The vectors responsible for biological transmission of the virus belong to the genus Culicoides (Diptera: Ceratopogonidae). In Senegal, studies on Culicoides are rare, out of date and did not specifically target the species in the vicinity of horses. Thus we initiated two studies in 2011 to better understand the dynamics and distribution of the Culicoides of Senegal and their involvement in the transmission of AHS virus (AHSV).
