Seasonal fluctuations of mosquitoes and application of two surveillance tools in Taibai Lake area of Jining City / 中国血吸虫病防治杂志

ABSTRACT

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 cap-ture of mosquitoes with a man-bait net trap,Gongfu Xiaoshuai mosquito lamp,and WJ-C mosquito sampler was performed to col-lect 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 perfor-mance against mosquitoes.The trapping results of WJ-C mosquito sampler were basically the same as the man-bait trapping meth-od,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.
