The vertical dimension constitutes an important niche axis along which mosquitoes may adjust their distribution. Here, we evaluated whether the vertical distribution of container‐inhabiting Aedes mosquitoes differs along a gradient of anthropogenic land‐use intensity within an urban landscape. Using a pulley system, we hung oviposition cups at three heights (ground level, 4.5, and 9 m) and in three habitats: forest, park, and a built environment. We hypothesized that mosquito abundance and diversity would be highest in the least disturbed forest habitat, decrease in the park, and be lowest at the UNC‐Greensboro campus. We also expected Aedes albopictus (Skuse) and Ae. triseriatus (Say) to mainly oviposit at ground level and Ae. hendersoni (Cockerell) at canopy height. Aedes albopictus was the most common species (68.8%) collected in all three habitat types and was the only species found in the built environment. In that habitat, Ae. albopictus exhibited a bimodal distribution with the lowest activity at the intermediate height (4.5 m). Aedes triseriatus (28.9%) did not differ in egg abundance between the forest and park habitats but did exhibit diverse vertical habitat use while avoiding the canopy in the park habitat. Aedes hendersoni (2.3%) was the most sylvatic species and oviposited only at ground level. Our results indicate that the vertical distribution of mosquitoes is affected by the type of habitat in which they occur, and that this variation could be driven via local‐scale modification of microclimatic factors.

水平分布会影响城市景观中原生和侵入容器的伊蚊的垂直分布。

垂直尺寸构成重要的生态位轴，蚊子可以沿着该生态位轴调整其分布。在这里，我们评估了在城市景观中，居住在容器中的伊蚊的垂直分布是否沿着人为土地利用强度的梯度变化。使用滑轮系统，我们将产卵杯悬挂在三个高度（地面，4.5和9 m）以及三个栖息地：森林，公园和建筑环境中。我们假设，在受干扰最少的森林栖息地中，蚊子的丰度和多样性最高，在公园中则减少，而在UNC-格林斯伯勒校区则最低。我们还预计白纹伊蚊（Skuse）和Ae。Triseriatus（Say）主要在地面和Ae上生卵。亨德索尼（Cockerell）在树冠高度。白纹伊蚊是在所有三种栖息地类型中最常见的物种（68.8％），并且是在建筑环境中发现的唯一物种。在那个栖息地，爱。白化病表现出双峰分布，在中间高度（4.5 m）处活性最低。森林和公园栖息地之间的白纹伊蚊（28.9％）的卵丰度没有差异，但在避免公园栖息地冠层的同时，也表现出多样化的垂直栖息地用途。埃及伊蚊（2.3％）是最多的sylvatic物种，仅在地面上产卵。我们的结果表明，蚊子的垂直分布受到其栖息地类型的影响，并且这种变化可能是通过局部改变微气候因子来驱动的。
