is an Asian and Middle Eastern malaria vector, and it has recently spread to the African continent. It is needed to measure how the malaria parasite infection in . is influenced by environmental factors to predict its expansion in a new environment. Effects of temperature and food conditions during larval periods on larval mortality, larval period, female wing size, egg production, egg size, adult longevity, and malaria infection rate were studied using a laboratory strain. Larval survival and female wing size were generally reduced when reared at higher temperatures and with a low food supply during the larval period. Egg production was not significantly affected by temperature during the larval period. Egg size was generally smaller in females reared at higher temperatures during the larval period. The infection rate of mosquitoes that fed on blood from malaria-infected mice was not affected by rearing temperature or food conditions during the larval period. Higher temperatures may reduce infection. . ; however, larger individuals can still be infective. We suggest that routinely recording the body size of adults in field surveys is effective in finding productive larval breeding sites and in predicting malaria risk.
是亚洲和中东地区的疟疾传播媒介，最近已传播到非洲大陆。需要衡量环境因素如何影响其体内疟原虫感染情况，以预测其在新环境中的扩散。使用实验室菌株研究了幼虫期温度和食物条件对幼虫死亡率、幼虫期、雌蚊翅大小、产卵量、卵大小、成虫寿命和疟疾感染率的影响。幼虫期在较高温度下饲养且食物供应不足时，幼虫存活率和雌蚊翅大小通常会降低。幼虫期温度对产卵量没有显著影响。幼虫期在较高温度下饲养的雌蚊所产的卵通常较小。取食感染疟疾小鼠血液的蚊子的感染率不受幼虫期饲养温度或食物条件的影响。较高温度可能会降低感染率。 ；然而，个体较大的蚊子仍可能具有传染性。我们建议在野外调查中常规记录成虫的体型，这对于找到有繁殖能力的幼虫滋生地和预测疟疾风险是有效的。
