Abstract:
Experiments were caried out on An.minimus F98 in laboratory conditions of 22+/- 1°C, 25+/- 1°C and 28 +/- 1°C, 70-80% RH. The time required for egg stage and egg hatching rate were negatively correlated with temperature. At 22 +/- 1°C, egg hatching rate was 84.1 %, the duration of the egg stage was 3-4 days. At 25+/-1°C and 28 +/-1oC, egg hatching rate was 77.3% and 65.5%, respectively, the time of the egg stage were 2-3 days. At higher temperature, the duration of larvae stage was shorter than at the lower temperature. 25°C was optimum temperature for larvae with 38% of larvae developed to adults. 1 day after molting, mosquitoes started feeding at all tested temperatures. At 22°C, blood feeding rate higher than at the higher temperatures. Number of eggs and egg hatching rate of mosquitoes that fed human blood were higher than mosquitoes fed on mice
