许多环境因素，生物的和非生物的相互作用，影响有机体的发展。鉴于埃及伊蚊作为人类病原体（包括登革热和黄热病）载体的重要性，了解环境因素（如温度、资源可用性和种内竞争）在发展过程中的影响对于人口控制至关重要。尽管已知发育性状与饮食和密度因素之间存在关联，但温度一直被认为是发育速率和存活率的主要驱动因素。为了确定这些关键因素的相对重要性，必须考虑条件的宽梯度。我们假设：1）饮食和密度，以及温度影响发育速率和存活率的变化，2）这些因素相互作用，这种相互作用对于理解发育性状的变化也是必要的。温度、饵料、密度及其双向交互作用是解释Ae幼虫期发育速率变化的重要因子。埃及蚊子。这些因素以及双向和三向相互作用显着相关的发育速度从孵化到出现。温度，而不是饮食或密度，显着影响少年死亡率。发展时间是heteroskedastic与最高的变化发生在极端的饮食和密度条件。所有这三个因素都显著影响了在发育过程中死亡的实验幼虫的存活曲线。复杂的相互作用可能导致发育速率的变化。为了更好地预测Ae的发育率和存活率的变化。此外，还必须考虑资源可用性和种内密度等因素，但绝不能排除温度。
Many environmental factors, biotic and abiotic interact to influence organismal development. Given the importance of Aedes aegypti as a vector of human pathogens including dengue and yellow fever, understanding the impact of environmental factors such as temperature, resource availability, and intraspecific competition during development is critical for population control purposes. Despite known associations between developmental traits and factors of diet and density, temperature has been considered the primary driver of development rate and survival. To determine the relative importance of these critical factors, wide gradients of conditions must be considered. We hypothesize that 1) diet and density, as well as temperature influence the variation in development rate and survival, 2) that these factors interact, and this interaction is also necessary to understand variation in developmental traits. Temperature, diet, density, and their two-way interactions are significant factors in explaining development rate variation of the larval stages of Ae. aegypti mosquitoes. These factors as well as two and three-way interactions are significantly associated with the development rate from hatch to emergence. Temperature, but not diet or density, significantly impacted juvenile mortality. Development time was heteroskedastic with the highest variation occurring at the extremes of diet and density conditions. All three factors significantly impacted survival curves of experimental larvae that died during development. Complex interactions may contribute to variation in development rate. To better predict variation in development rate and survival in Ae. aegypti, factors of resource availability and intraspecific density must be considered in addition, but never to the exclusion of temperature.
