The effect of temperature on the survival of Simulium hargreavesi larvae reared in the laboratory

The performance of Stmuhum hargreasvesi larvae with regards to pupation success and pupal emergence at rwo temperatui e regimes were investigated. S. hargreavesi larvae showed better success a? the higher temperature of 2d ”C 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 °C was 21.7 with a mean survival index Of 511.2 suggesting that high temperatures favour survival and pupation. It is therefore apparent here that high temperature ana flow rates favour the development of the blackfly larvae in the laboratory. These observations can be useful in developing fly control strategies in Africa.
