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.
