Adults of Anopheles pharoensis and An. multicolor were held under cycling environmental conditions in the laboratory to examine the duration of the gonotrophic cycles, survival and life expectancy, and to examine the life table characteristics of F1 larvae. The first gonotrophic cycle took 6.14 and 7.37 days for An. pharoensis and An. multicolor, respectively. Subsequent gonotrophic cycles for the 2 species were shorter. Daily survival rates of An. pharoensis and An. multicolor in the laboratory were 0.95 and 0.93, respectively. The parity rate of field-collected females and estimates of the duration of the gonotrophic cycle yielded daily survivorship estimates of 0.89 and 0.80 for An. pharoensis and An. multicolor, respectively. Mean life expectancy at emergence was 19.0 days for An. pharoensis compared with 17.9 days for An. multicolor. Survivorship from egg eclosion to adult emergence and development time were similar for both species. Both the duration of gonotrophic cycles and mean life expectancies indicated that An. pharoensis had a greater potential to serve as a malaria vector than An. multicolor.
在实验室中，将法老按蚊和多彩按蚊的成虫置于循环环境条件下，以研究其生殖营养周期的持续时间、存活率和预期寿命，并研究F1幼虫的生命表特征。法老按蚊和多彩按蚊的第一个生殖营养周期分别为6.14天和7.37天。这两个物种随后的生殖营养周期较短。法老按蚊和多彩按蚊在实验室中的每日存活率分别为0.95和0.93。野外采集的雌蚊的产雌率和生殖营养周期持续时间的估计得出，法老按蚊和多彩按蚊的每日存活率估计分别为0.89和0.80。法老按蚊羽化时的平均预期寿命为19.0天，而多彩按蚊为17.9天。两种按蚊从卵孵化到成虫羽化的存活率和发育时间相似。生殖营养周期的持续时间和平均预期寿命均表明，法老按蚊作为疟疾传播媒介的潜力比多彩按蚊更大。
