Abstract: Objective To investigate the application of unmanned aerial vehicle (UAV) in collecting mosquito specimens and the distribution of mosquitoes at different heights. Methods From late August to early September in 2021, UAV flying with a sweep net (UAVN) was used to collect mosquitoes in a farm in Tianjin, China, and the efficiency of collecting mosquitoes was compared between UAVN and the labor hour method (LHM). The distribution of mosquitoes at different heights was analyzed using UAVN. Results UAVN had a higher efficiency of collecting mosquitoes than LHM (34.75 mosquitoes/10 minutes vs 3.38 mosquitoes/10 minutes). The sweep net carried by UAV collected the highest number of mosquitoes at the height of 5.00 m, and mosquitoes were hardly caught when height exceeded 12.00 m or wind speed exceeded 4.00 m/s. Conclusion UAVN has the advantages of no restrictions on terrain and habitat and high efficiency in collecting mosquito specimens. It and can be used as a tool for mosquito specimen collection. Mosquitoes are mainly distributed in the lower space; however, mosquitoes would fly up and down under the agitation of the UAV fan, which may lead to differences between experimental results and actual distribution, and therefore, further studies are needed for clarification.

摘要： 目的 探讨无人机在蚊虫标本采集中的应用，调查不同高度的蚊虫分布。方法 在天津某农场，于2021年8月下旬到9月上旬，通过无人机挂网飞行的方式捕虫，对比人工小时法和无人机捕获蚊虫效率，考察不同高度的蚊虫分布等。结果 无人机标本捕获效率（34.75只/10 min）高于人工小时法（3.38只/10 min），无人机携带的捕虫网在5.00 m高度采集的蚊虫数量最多，高度>12.00 m或风速>4.00 m/s时几乎无法采集到蚊虫。结论 无人机进行蚊虫标本采集，具有不限地形、不限生境、捕获效率高等优点，可作为蚊虫标本采集工具。蚊虫主要分布在低层空间，但是在无人机的风扇搅动下，蚊虫会上下翻飞，其结果可能与真实分布存在差异，需要进一步探讨。
