目的了解2011-2013年浙江省居民区病媒生物种群构成、密度及其变化趋势,为浙江省病媒生物防控提供理论基础。方法蚊、鼠、蝇、蜚蠊分别采用诱蚊灯法、夹夜法、笼诱法和粘捕法进行监测。结果 2011-2013年浙江省蚊密度分别为1.52、1.33和1.62只/(灯·h),牲畜棚最高,以淡色/致倦库蚊为优势蚊种,占捕获总数的57.44%,高峰期为6-8月;蝇密度分别为8.77、5.67和3.47只/笼,2011-2012年以大头金蝇为主要优势蝇种,其次为家蝇,2013年则以家蝇为主要优势种,其次为大头金蝇;鼠密度分别为0.89%、0.81%和0.78%,以褐家鼠为优势鼠种,占捕获总数的57.70%,全年均有鼠类活动;蜚蠊密度分别为0.54、0.37和0.35只/张,以德国小蠊为主要优势种,占捕获总数的88.42%。结论通过2011-2013年监测数据分析,基本掌握了浙江省居民区病媒生物数量状态,建议各地市按照浙江省病媒生物流行的实际情况采取防控措施。
Objective To understand the composition, density and trend of vector population in residential areas in Zhejiang Province from 2011 to 2013, and provide a theoretical basis for vector control in Zhejiang Province. Methods Mosquitoes, rats, flies and cockroaches were monitored by mosquito lamp method, trap method, cage induction method and stick catching method respectively. Results The mosquito density in Zhejiang Province during the period from 2011 to 2013 was 1.52, 1.33 and 1.62 light / h, respectively, and the highest in livestock sheds. The dominant species were Culex pipiens / Culex quinquefasciatus, accounting for 57.44% of the total catch. The peak was From June to August, the flies density was 8.77, 5.67 and 3.47, respectively. The main dominant flies were from 2013 to 2012, followed by housefly, while housefly was the dominant species in 2013, followed by The density of rodents was 0.89%, 0.81% and 0.78%, respectively. The dominant species was Rattus norvegicus, accounting for 57.70% of the total number of captured rodents. The rodents’ density was 0.54 and 0.37 0.35 / Zhang, with German cockroach as the dominant species, accounting for 88.42% of the total captured. Conclusion Through the monitoring data analysis from 2011 to 2013, it basically grasped the quantity and status of vectors in residential areas in Zhejiang Province and suggested that all cities and districts should take prevention and control measures according to the actual situation of vector-borne biotopes in Zhejiang Province.
