Abstract:

Objective To identify the species compositions, densities and seasonal fluctuation of vectors in Zhejiang province from 2011 to 2013, the aim is to provide scientific and technical support for the prevention and control of vectors. Methods Mosquitoes, flies, rodents and cockroaches were monitored with mosquito lamps, cage traps, traps set at night and glue traps. Results From 2011 to 2013, the mosquito density was 1.52, 1.33 and 1.62 per lamp-hour, respectively, with the highest density found in livestock pens, and the dominant species were Culex pipiens pallen (sure not Cx. quinquefasciatus), accounting for 57.44%. Mosquitoes appeared from April and peak in June through August. The fly density was 8.77, 5.67 and 3.47 per cage, respectively, with the dominant species were Chrysomya megacephala from 2011 to 2012, which became Musca domestica in 2013. The rodent density was 0.89%, 0.81% and 0.78%, respectively, with the dominant species were Rattus norvegicus, accounting for 57.70%. Rodents were observed throughout the whole year. The cockroach density was 0.54, 0.37 and 0.35 per glue trap, respectively, with the dominant species were Blattella germanica, accounting for 88.42% . Conclusion Species compositions, densities and seasonal fluctuation of vectors in Zhejiang province were analyzed through 3-year surveillance, mitigation measures should be taken accordingly to control vectors.

摘要:

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。
