三种捕蚊器在伊蚊成蚊监测中的效果比较

Comparative observations on the outcomes of three devices in trapping adult Aedes

目的比较三种捕蚊器对白蚊伊蚊成蚊的引诱效果。方法选择苏州市城镇居民区和环境监测中心进行现场试验,监测时间为每天15:00-15:30开始,持续2 h。每处生境分别放置三种捕蚊器,对捕获的蚊虫进行分类鉴定和计数,依次轮换放置捕蚊器的位置,共计试验三轮。结果BG-trap捕蚊器监测发现,白纹伊蚊成蚊活动有两个高峰,分别为5:00-7:00和15:00-17:00。在城镇居民区,功夫小帅、迈斯翠和BG-trap三种捕蚊器白纹伊蚊成蚊捕获数分别为2.0、0.9、57.5只/盏;在环境监测中心,功夫小帅、迈斯翠和BG-trap三种捕蚊器白纹伊蚊成蚊捕获数分别为4.7、1.3、42.0只/盏。BG-trap捕蚊器还可捕获少量淡色库蚊。结论三种捕蚊器均能捕获一定数量白纹伊蚊成蚊,其中BG-trap捕蚊器白纹伊蚊成蚊捕获率最高,是一款值得推广的伊蚊监测工具。

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.
