Dispersion of malaria vectors in a community near the city of Iquitos (2021)

<b>Dispersion of malaria vectors in a community near the city of Iquitos.</b>
<br><br><b>Study description</b> Malaria vector mosquitoes were collected for 12 consecutive months (February 2021 to January 2022) in the community of Santa Rita, located 30 minutes from the city of Iquitos. Using satellite images, five different clusters were identified: Forest, Houses, Orchards, Flood-prone areas, and Vegetation Recovery patches. Mosquitoes were collected in all five clusters simultaneously for four nights each month to understand how malaria vectors disperse in the different sampled habitats. It was found that the distribution of vector mosquitoes occurs in all clusters throughout the year. Depending on the dry or rainy season, each cluster changes its mosquito abundance and diversity.

**伊基托斯市周边社区的疟疾媒介分布扩散研究**

**研究概况** 本研究于2021年2月至2022年1月，在距伊基托斯市车程约30分钟的圣丽塔（Santa Rita）社区开展，连续12个月采集疟疾媒介蚊（malaria vector mosquito）。研究人员借助卫星影像（satellite images）识别出五类生境斑块：森林、居民区、果园、易涝区与植被恢复斑块。每月连续四个夜晚同时在全部五类生境中开展蚊虫采集工作，以探究疟疾媒介在不同采样生境中的扩散规律。研究结果显示，全年所有生境斑块均有疟疾媒介蚊分布；且随旱季、雨季的交替，各斑块的蚊虫丰度与多样性均会发生相应变化。
