本研究旨在评估产卵的垂直模式和时间变化的蚊子物种的分布在里约热内卢州的大西洋森林，巴西的一个地区，特别是潜在的黄热病病毒载体的行为和产卵。从瓜皮亚库生态保护区（巴西雷瓜）采集了苔藓样本，该保护区包括一片受到一定干扰的森林，动植物种类繁多。共采集标本5，458件（7属10种）。白斑血姑是最常捕获的物种，占所采集标本的73%。物种丰富度和多样性在地面诱蚊产卵器采集的样品中最高，随高度的增加而降低。物种组成也有显着差异的高度。最大的物种之间的差异检测诱卵器设置在地面水平和那些设置在7米和9 m; Hg。leucocelaenus、Limatusdurhamii和Limatusparaensis对这些差异贡献最大。采样月份和气候变量对物种丰富度和多样性有显著影响。物种多样性和丰富度随高度的增加而降低，表明越靠近地面越有利于蚊子的繁殖。物种组成也表现出垂直差异。
This study aimed to assess the vertical patterns of oviposition and temporal changes in the distribution of mosquito species in an area of the Atlantic Forest in Rio de Janeiro State, Brazil, and in particular, the behavior and oviposition of potential yellow fever virus vectors. Mosquito samples were collected from the Ecological Reserve Guapiacu (REGUA, Brazil), which includes a somewhat disturbed forest, with a large diversity of plants and animals. In all, 5,458 specimens (ten species from seven genera) were collected. Haemagogus leucocelaenus was the most frequently captured species, representing 73% of the specimens collected. Species richness and diversity were the highest in the samples collected from the ground-level ovitraps and decreased with height. Species composition also differed significantly among heights. The largest species differences were detected between ovitraps set at the ground level and those set at 7 m and 9 m; Hg. leucocelaenus, Limatus durhamii, and Limatus paraensis contributed most to these differences. Sampling month and climatic variables had significant effects on species richness and diversity. Species diversity and richness decreased with height, suggesting that the conditions for mosquito breeding are more favorable closer to the ground. Species composition also showed vertical differences.
