Urbanization has caused an increase in favorable habitats for Aedes aegypti (Diptera: Culicidae), given their ability to reproduce in small and often non‐degradable artificial water‐containers. While much work has been done on Ae. aegypti biology and ecology in urban landscapes, the role of shading on immature stages as an independent factor from temperature, and any possible interactions between these factors, remains unexamined. We assessed how temperature and shading affected egg hatch‐rate, larval/pupal mortality, and larval development to adult stage under different factorial temperature (28; 31; 34; 37; 40° C) and shade (0%, 3,100 lux; 40%, 1,860 lux; 75%, 775 lux; 100%, 0 lux) regimes. Hatch‐rate was significantly lower at 37° C (57 %), and no eggs hatched at 40° C. There was no significant effect caused by shading on hatchability. Larval and pupal mortality at 37° C was significantly higher (35%) compared to lower temperature groups, while the effects of shading were emergent at low temperatures. Developmental times from hatching to adult emergence were significantly reduced with increasing temperatures and with greater light exposures. The eco‐physiological response of Ae. aegypti larvae to temperature and light regimes suggest a photosensitivity previously unstudied in this species.

温度和阴影对埃及伊蚊(Diptera:Culicidae)死亡率和发育率的影响。

城市化导致埃及伊蚊(Diptera:Culicidae)的有利栖息地增加,因为它们有能力在小型且通常不可降解的人造水容器中繁殖。尽管有关Ae的工作已经很多。埃及尚未研究城市景观中的生物学和生态学,未成熟阶段的阴影作为温度的独立因素的作用以及这些因素之间可能存在的相互作用。我们评估了温度和阴影在不同的析因温度(28; 31; 34; 37; 40°C)和阴影(0%,3,100 lux; 40)下如何影响卵的孵化率,幼虫/ pu的死亡率以及成虫的​​发育。 1,860 lux; 75%,775 lux; 100%,0 lux)方案。孵化率在37°C(57%)时显着降低,在40°C时没有卵孵化。遮光对孵化率没有明显影响。与较低温度的组相比,在37°C时的幼虫和mortality死亡率要高得多(35%),而在低温下会出现阴影效应。从孵化到成年出苗的发育时间随着温度的升高和更大的曝光量而大大减少。的生态生理反应e 埃及伊蚊幼虫对温度和光照的影响表明该物种以前未研究过光敏性。
