The Comparative Field Evaluation of Four Different Traps for Mosquito Surveillance in the Republic of Korea

초록

Simple Summary Mosquito collection traps are an essential tool for monitoring mosquito density and species distribution. Various traps are used in mosquito surveillance projects in the Republic of Korea. However, there is a lack of comparative analysis of these traps. Therefore, we evaluated four traps that are widely used for mosquito surveillance. BLT showed superior collection efficiency in terms of the number of collected individuals and species evenness, whereas BGT showed the highest species diversity among all the traps. DMS is well adapted to urban areas and has an advanced function that can automatically count the number of mosquitoes. In our summary, we provide information about the traps and guidance for planning new mosquito surveillance projects.Abstract Monitoring mosquito populations is essential for controlling mosquito-borne diseases, and the selection of mosquito traps should be tailored to specific surveillance objectives. Here, we tested four mosquito traps for their efficiency and applicability: the Nozawa-style black light trap (BLT), BG-sentinel trap II (BGT), UV-LED Blackhole Plus Mosquito Buster trap (LED), and digital mosquito monitoring system (DMS). The traps were rotated weekly for a 24 h cycle at the same location for 13 weeks. Overall, 1649 female mosquitoes belonging to seven genera and sixteen species were collected by the traps. The traps exhibited differences in both the number of collected individuals and species composition. The BLT showed superior collection efficiency in terms of the number of collected individuals and species evenness, whereas the BGT showed the highest species diversity among all the traps. Thus, the BLT and BGT are the best choices for effective mosquito surveillance based on trap performance. Additionally, despite the relatively low efficiency of the LED and DMS observed in this study, the LED is known to be efficient when used for indoor conditions such as cowsheds, while the DMS has an advanced function that can automatically count the number of mosquitoes. Thus, our findings provide significant guidelines for planning new mosquito surveillance projects in the ROK.
