济宁市太白湖湿地蚊媒季节消长及2种监测工具应用效果

目的 调查济宁市太白湖湿地蚊媒季节消长水平，比较功夫小帅诱蚊灯和WJ?C全自动高效蚊虫采样器的诱蚊效果。方法 2017年6-10月分别采用人饵帐诱捕蚊法、功夫小帅诱蚊灯、WJ?C全自动高效蚊虫采样器诱捕蚊媒，对太白湖湿地的成蚊种类、季节消长等情况进行调查分析。结果 人饵帐诱捕蚊法共捕获成蚊10 914只，包括5属13种；三带喙库蚊、淡色库蚊和常型曼蚊为当地的优势蚊种，三者占捕蚊总数的77.41%；黄色柯蚊比例明显上升。各种成蚊均于6月开始出现，7-8月为活动高峰期。2种诱蚊工具均有较好的诱捕效果，WJ?C全自动高效蚊虫采样器诱蚊效果与人饵帐诱法基本一致；诱蚊灯对常型曼蚊和黄色柯蚊的诱捕效果明显低于人饵帐诱法。结论 济宁市太白湖湿地蚊虫结构有所变化，应加强监测。诱蚊灯和WJ?C全自动高效蚊虫采样器均具有较好的诱蚊效果，但各有优劣，监测过程中应注意监测方法的一致性。

Seasonal fluctuations of mosquitoes and application of two surveillance tools in Taibai Lake area of Jining City

Objective To investigate the seasonal fluctuations of mosquitoes in Taibai Lake area of Jining City， and evaluate the application effects of two mosquito trapping tools （Gongfu Xiaoshuai mosquito lamp and WJ?C mosquito sampler）， so as to provide references for the effective surveillance， prevention and control of local mosquito vectors. Methods The overnight capture of mosquitoes with a man?bait net trap， Gongfu Xiaoshuai mosquito lamp， and WJ?C mosquito sampler was performed to collect mosquitoes. The species of adult mosquitoes and seasonal fluctuations were investigated and analyzed. Results A total of 10 914 mosquitoes belonging to 13 species， 5 genera were collected with the overnight capture of mosquitoes with the man?bait net trap， and Culex tritaeniorhynchus， Cx. pipiens palllen and Mansonia uniformis were the dominant species， accounting for 77.41% of the total. The proportion of Coquillettidia ochracea increased significantly. All the adult mosquitoes appeared in June， and reached the density peak in July and August. Both of the two surveillance tools showed relatively sensitive capture performance against mosquitoes. The trapping results of WJ?C mosquito sampler were basically the same as the man?bait trapping method， however， the amount of Mansonia uniformis and Coquillettidia ochracea collected by Gongfu Xiaoshuai mosquito lamp was significantly lower than that of the man?bait trapping method. Conclusions The mosquito species are varied in Taibai Lake area of Jining City. Therefore， monitoring should be strengthened. In addition， the two mosquito trapping tools are sensitive， but they have both advantages and disadvantages， thus we should better pay attention to the consistency of monitoring methods in use.
