Abstract: Objective To compare the efficacy of mosquito trapping between CO₂ and light trapping lamps and to provide a basis for effective mosquito surveillance. Methods From August to October, 2018, different habitats in Qingdao were randomly selected, CO₂ and light trapping lamps were simultaneously used for mosquito surveillance, and captured adult mosquitoes were collected and classified. The Mann-Whitney U test was used to compare the mosquito density, and the χ² test was used to compare the proportion of mosquito species. Results Both trapping lamps were able to trap mosquitoes, and the mosquito density determined by CO₂ trapping lamp (25.00/lamp·night) was significantly higher than that determined by light trapping lamp (4.50/lamp·night) (Z=-2.915, P=0.004). The proportions of mosquitoes and female mosquitoes captured by CO₂ trapping lamp (94.90% and 99.68%) were significantly higher than the proportions of those captured by light trapping lamp (11.94% and 77.27%) (χ²=2 268.789, P=0.000; χ²=315.951, P=0.000), and the mosquito species compositions captured by the two mosquito trapping lamps were significantly different (χ²=18.903, P=0.000). Conclusion Both CO₂ and light trapping lamps can be used for mosquito surveillance, and researchers can choose one or more surveillance tools according to the study objective to comprehensively analyze and survey the density, population, and seasonal variation of adult mosquitoes.
