This study was conducted in a meteorological tower located in the Caxiuanã Forest (municipality of Melgaço, Pará, Brazil) with the aim of assessing the vertical stratification of species of Haemagogus and Sabethes, potential vectors of the yellow fever virus. To investigate the role of microclimates in mosquito stratification, bimonthly collections were conducted at ground level (0 m), 8 m, 16 m and 30 m (canopy level), with the aid of entomological nets and suction tubes, from July 2005-April 2006. A total of 25,498 mosquitoes were collected; specimens of Sabethes sp. and Haemagogus janthinomyswere found mostly at heights of 16 m and 30 m while Hg. leucocelaenus was most frequently observed at ground level. The largest number of vector species was collected during the rainiest months, but this difference between seasons was not statistically significant. However, the number of Hg. janthinomys was positively correlated with variations in temperature and relative humidity.
本研究在巴西帕拉州梅加乔市的卡西亚万纳森林中的气象塔进行，旨在评估潜在的黄热病病毒载体 Haemagogus 和 Sabethes 物种的垂直分层情况。为了研究微气候在蚊子分层中的作用，我们于 2005 年 7 月至 2006 年 4 月间每隔两个月在地面（0 米）、8 米、16 米和 30 米（树冠层）使用昆虫网和吸蚊管进行了采集。共收集了 25498 只蚊子；发现 Sabethes sp. 和 Haemagogus janthinomys 主要存在于 16 米和 30 米的高度，而 Hg. leucocelaenus 则最常出现在地面。在降雨量最大的月份里，采集到的媒介物种数量最多，但季节之间的这种差异没有统计学意义。然而，Hg. janthinomys 的数量与温度和相对湿度的变化呈正相关。
