Abstract: The performance of Simulium hargreasvesi larvae with regards to pupation success and pupal emergence at two temperature regimes were investigated. S. hargreavesi larvae showed better success at the higher temperature of 23 0C with a mean percentage pupation index of 30.0 and a mean percentage survival index of 619.5. The mean percentage pupation index at 19 oC was 21.7 with a mean survival index 0f 511.2 suggesting that high temperatures favour survival and pupation. It is therefore apparent here that high temperature and flow rates favour the development of the blackfly larvae in the laboratory. These observations can be useful in developing fly control strategies in Africa.
