dc.description.abstract A light-trap survey was undertaken of the species composition, seasonal abundance and parity of Culicoides at Roma, Lesotho, to establish whether the likely vectors for bluetongue and African horse sickness occur in this area as well as the chance of transmission. A total of 34 catches was made between 21 September 1985 and 24 September 1986; 32 819 Culicoides were caught belonging to 19 species. Culicoides numbers rapidly built up from December to a peak in February which implies that this may also be the optimum time for virus transmission. The number of Culicoides dropped sharply in April with the onset of cooler conditions. C. zuluensis was the dominant species forming 69,6 % of the totalled catches, followed by C. pycnostictus with 11,7%. C. imicola, the only proven vector of bluetongue, was never abundant representing only 4,4% of the midges caught. The parous rate for each of the 2 commonest species was low, implying a low vector capacity. en
