未来几年预测的气候变化很可能导致节肢动物传播的病原体媒介的分布和种群发生重大变化。需要描述温度变化对特定病媒生活史特征的影响，以便更准确地确定这种变化如何影响病媒传播疾病的流行病学模式。本研究测定了16、20、24、28和32℃温度对野外种群和定殖种群的发育时间、未成熟种群存活率、成虫存活率、蚊子大小、取血量和繁殖力的影响。我们的研究结果表明，温度对所有这些特征都有显著影响，但这种影响的程度有时在温度之间是不一致的，并且是种群和物种特异性的。将定殖蚊子与野外种群进行比较，一般显示成蚊和未成熟蚊子的存活率下降，取血量和产卵量增加，温度的影响存在显著差异，表明这些定殖蚊子不能完全代表自然种群。对一般野外种群的调查结果表明，温度升高可能会加速蚊子的发育，在温度低于24°C时这种影响更大，但温度也会显著增加死亡率。在野外种群中，Cx。温度升高对餐馆的影响最大，每增加一次温度，餐馆的寿命相对于其他物种缩短，成年和未成熟的死亡率显著增加。尽管Cx的地理范围具有独特的气候特征。致倦库蚊和Cx。没有证据表明，库蚊对温度范围有显著的物种特异性适应。综上所述，这些结果表明，在测量温度对病媒生物种群的影响时，必须考虑地理区域以及物种和种群差异。
Climatic changes forecasted in the coming years are likely to result in substantial alterations to the distributions and populations of vectors of arthropod-borne pathogens. Characterization of the effect of temperature shifts on the life history traits of specific vectors is needed to more accurately define how such changes could impact the epidemiological patterns of vector-borne disease. Here, we determined the effect of temperatures including 16, 20, 24, 28, and 32°C on development time, immature survival, adult survival, mosquito size, blood feeding, and fecundity of both field and colonized populations of the Culex mosquitoes Culex pipiens L., Culex quinquefasciatus Say, and Culex restuans Theobald. Our results demonstrate that temperature significantly affects all of these traits, yet also that the extent of this effect is at times incongruent among temperatures, as well as being population and species-specific. Comparisons of colonized mosquitoes with field populations generally demonstrate decreased adult and immature survival, increased blood feeding and egg production, and significant variation in the effects of temperature, indicating that such colonies are not fully representative of natural populations. Results with field populations in general indicate that increases in temperature are likely to accelerate mosquito development, and that this effect is greater at temperatures below 24°C, but also that temperature significantly increases mortality. Among field populations, Cx. restuans were most affected by temperature increases, with decreased longevity relative to other species and significant increases in adult and immature mortality measured with each incremental temperature increase. Despite the unique climates characteristic of the geographic ranges of Cx. quinquefasciatus and Cx. pipiens, evidence of significant species-specific adaptation to temperature ranges was not seen. Taken together, these results indicate that geographic region, as well as species and population differences, must be considered when measuring the effect of temperature on vector populations.
