Abstract:

Objective To determine the species composition and population dynamics of mosquitoes in Wenzhou city, Zhejiang, China, to analyze the population trends in different mosquito breeding environments, and to provide a scientific basis for the city mosquito control operations. Methods Night light traps were utilized to conduct monthly monitoring in 11 counties of Wenzhou city from April to November during 2010-2013. Results A total of 14 597 adult mosquitoes were captured during the monitoring period, where Culex pipiens pallens was the predominant species, accounting for 82.44% of the total number of mosquitoes. The peak of adult mosquito density appeared from July to August, the highest density appeared in August or 2011, which is 2.83 mosquitoes per light-hour. The mosquito borne disease incidence peak was in July to August. A total of 37 cases of and 18 cases of were reported during 2010-2013. The highest adult mosquito density was in the livestock shed, which was 2.74 per light - hour among different environments. Conclusion The surveillance results of mosquito density and its seasonality provide guidance for urban mosquito control. The association of mosquito density with mosquito borne diseases should be analyzed to reflect the efficiency of mosquito control operations.

摘要:

目的 了解和掌握温州市蚊虫种类构成及密度动态,分析不同环境蚊虫孳生变化趋势,为该城市蚊虫防制提供科学依据。方法 于2010-2013年每年的4-11月采用诱蚊灯法在温州市11个县(市、区)开展逐月监测。结果 监测期间共捕获成蚊14 597只,其中以淡色库蚊为优势蚊种,占捕蚊总数的82.44%。成蚊密度高峰期集中在7-8月,其中密度最高出现在2011年8月,为2.83只(/ 灯·h);蚊媒疾病发病数量高峰也集中在7-8月,3年合计分别为37例和18例。不同生境中牲畜棚成蚊密度最高,密度为2.74只(/ 灯·h)。结论 蚊虫密度监测结果和季节消长变化趋势可有效地为城市提供防治依据,并将监测结果与蚊媒传染病进行关联分析,为城市蚊虫及蚊媒病的防制提供指导意见。
