在实验室条件下大量饲养蚊子是几种新的控制技术的重要组成部分，这些技术依靠释放雄性蚊子来控制蚊子数量。虽然以前的工作已经调查了幼虫密度和饮食量对群体生产力的影响，容器的大小，其中发生幼虫发育的作用相对被忽视。我们研究了容器大小在塑造生活史中的作用，以及这种作用如何随埃及伊蚊的密度和食物供应而变化，埃及伊蚊是一种重要的疾病媒介和大规模饲养操作的目标。对于每种处理组合，测量未成熟发育时间和存活率以及成体大小和繁殖力，然后将其组合成生产力的量度。我们还研究了幼虫聚集行为如何随容器大小而变化。容器大小对生活史性状和总体生产力有重要影响。特别是，增加容器的大小加剧密度和饮食的影响不成熟的发展时间。当幼虫以高密度（1.4幼虫/毫升）饲养时，容器大小也会影响生产力。在这些处理中，估计大型容器的生产率指标显著低于中型或小型容器。无论容器大小，幼虫更有可能被观察到的容器的外边缘，即使这导致极高的局部密度。我们讨论了如何容器的大小和幼虫聚集反应可能会改变平衡的能量输入和输出形状的发展和生产力。
Mass-rearing of mosquitoes under laboratory conditions is an important part of several new control techniques that rely on the release of males to control mosquito populations. While previous work has investigated the effect of larval density and diet amount on colony productivity, the role of the size of the container in which larval development takes place has been relatively ignored. We investigated the role of container size in shaping life history and how this varied with density and food availability in Aedes aegypti, an important disease vector and target of mass-rearing operations. For each treatment combination, immature development time and survival and adult body size and fecundity were measured, and then combined into a measure of productivity. We additionally investigated how larval aggregation behaviour varied with container size. Container size had important effects on life history traits and overall productivity. In particular, increasing container size intensified density and diet effects on immature development time. Productivity was also impacted by container size when larvae were reared at high densities (1.4 larva/ml). In these treatments, the productivity metric of large containers was estimated to be significantly lower than medium or small containers. Regardless of container size, larvae were more likely to be observed at the outer edges of containers, even when this led to extremely high localized densities. We discuss how container size and larval aggregation responses may alter the balance of energy input and output to shape development and productivity.
