Reduction of mosquito communities using the mass trapping method

Abstract

AbstractThis study was conducted to demonstrate the effect of the mass trapping of mosquitoes as an eco‐friendly physical control method. It was conducted at the Ansan Hwarang Auto Camping Site in Gyeonggi Province, Republic of Korea. The study period was approximately 1 month (from July 2 to July 30, 2018). Inner and outer traps were installed to control mosquitoes inside and outside the study area. The inner trap consisted of 5 digital mosquito monitoring system units placed inside the study area, whereas the outer trap included 26 MOSHOLE‐PRO units installed at 30 m intervals outside the study area. Both the inner and outer traps used carbon dioxide as an attractant. Additionally, the outer traps were grouped close to each inner trap using distance analysis and designated as Sn (n, inner trap number). According to the study results, analysis of the daily mean temperature and daily mean precipitation from 2017 to 2019 showed that the meteorological data were statistically insignificant. During the mass trapping period, the outer traps had the highest mean number of mosquitoes in the S1 group, whereas the other groups exhibited statistically similar results. Analysis of the mean number of mosquitoes in the inner trap confirmed a mean reduction rate of 59.39% through mass trapping, and the results were statistically significant (P < 0.001). This study confirms the effectiveness of mass trapping in reducing mosquito communities and suggests the possibility of creating mosquito‐free zones by targeting mosquitoes both inside and outside the study area.
