Abstract: Objective To compare the trapping effect of three mosquito trap devices(Kungfu Xiaoshuai, Maxttrac,BG-Mosquitaire CO₂ ) in ensnaring adult Aedes. Methods The field experiments were carried out in residential areas and environment surveillance center in Suhou City. Three types of mosquito traps were placed in individual habitat to monitor adult Aedes at 15:00 or 15:30 for 2 hours each day. The experiments were run for three rounds by in turn exchanging the trapping device among the experimental sites. The captured mosquitoes in each trap were counted, and the species were identified for comparing the outcomes of three difference devices in mosquito catching. Results BG-trap showed that the activities of Aedes albopictus were in two peaks, i. e. , between 5:00-7:00 am and 15:00-17:00 pm. The number of mosquitoes trapped in the residential areas and the environment surveillance center by Kungfu Xiaoshuai, Maxttrac and BGMosquitaire CO₂ trap was 2. 0, 0. 9 and 57. 5 heads; and 4. 7, 1. 3 and 42. 0 capita, respectively, by each device. In addition, the BG-trap had caught small number of Culex pipiens pallens. Conclusion The three types of mosquito traps can capture some Aedes albopictus, yet BG-trap is worthy of recommendation because it is more effective than the other two devices.
