摘要: Summary Although African horse sickness (AHS) is considered to be endemic in Namibia, limited data on its Culicoides midge vector (Diptera: Ceratopogonidae) are available. The principal study objective was determine the presence, species composition and richness diversity of adults during colder drier months Khomas region central Namibia. Five sites were selected, ranging from relatively high low altitudes with annual rainfall. Onderstepoort suction UV‐light traps used for collection run winter 6 July 21 September 2009. A 25 9 091 individuals collected 34 collections. abundance proven AHS virus, imicola, varied 94% near Windhoek at a altitude higher rainfall, 12% site situated farthest south‐west, lowest This abundance, coupled presence cycling host (zebra) area, imply that virus may overwinter
