Abstract

In a country-wide survey of Culicoides in Nigeria 31 species were caught in light-traps set on the eaves of livestock pens. Three species, namely C. imicola Kieff., C. schultzei (End.) and C. milnei Aust., were most numerous and were found in all parts of the country. C. austeni C., I. & M. was predominant in mangrove swamps, C. schultzei in the hot Sudan zone and C. milnei was dominant on the plateaux. C. imicola and C. milnei were predominant in the forest zone while C. schultzei and C. imicola were dominant in the savanna zones. C. quinquelineatus Goetgh. was a southern species and was replaced in the north by C. moreli Clastrier. Peak catches of most species were between 01.00 and 05.00 h and a large proportion of the Culicoides were engorged with blood. The presence of large numbers of engorged Culicoides, especially C. imicola and C. milnei, around livestock indicates the danger of bluetongue virus transmission.
