一项为期3年的实地研究的幼虫种群的伊蚊sierrensis，一种常见的北美树洞蚊子，没有证据表明密度依赖的幼虫死亡率，但显示蛹重量的女性是呈负相关的幼虫密度。对野生成虫种群的抽样表明，一般来说，较大的成虫比较小的成虫寿命长。在自然界中，血餐之间的间隔估计为8天。在自然界中观察到的幼虫密度范围内估计了雌性的感染寿命（用于传播线虫，犬恶丝虫）的总预期。由于这些估计数在中等种群密度时可能最大，幼虫密度的降低可能导致成虫传播疾病的能力增加。
A 3-year field study of larval populations of Aedes sierrensis, a common North American tree-hole mosquito, produced no evidence for density-dependent larval mortality, but revealed that pupal weight of females was inversely correlated with larval density. Sampling of a wild adult population indicated that, in general, larger adults lived longer than smaller ones. The interval between blood meals in nature was estimated as 8 days. The total expectation of infective life (for transmission of a nematode, Dirofilaria immitis) for females was estimated within the range of larval densities observed in nature. As these estimates may be maximal at intermediate population densities, reduction of larval density may result in an increase in the capacity of the adult population to transmit disease.
