摘要
目的掌握浙江省磐安县主要病媒生物种群密度及其消长规律,为控制病媒生物的危害提供科学依据。方法采用诱蚊灯法监测蚊密度,笼诱法监测蝇密度,粘捕法监测蜚蠊密度,夹夜法监测鼠密度。结果 2005-2010年磐安县蚊类平均密度为2.04只(/灯·h),以淡色/致倦库蚊为优势蚊种,占捕获总数的71.81%;蝇密度指数为1.83只/笼,优势种为家蝇和大头金蝇,分别占捕获总数的52.62%和37.81%;蜚蠊密度为0.91只/张,优势种为德国小蠊,占捕获总数的92.10%;鼠密度为0.89%,优势种为针毛鼠,占捕获总数的37.60%。蚊和蝇5月开始活动,蚊类于7月达到高峰,蝇类6-8月达到高峰;蜚蠊和鼠全年均有活动,3-10月蜚蠊密度较高,鼠密度高峰一般出现在9月。结论基本掌握了磐安县病媒生物的种群构成和季节消长规律。
Objective To determine the density of primary vector species and their seasonal fluctuation in Pan’an county for improvement of prevention and control strategies. Methods Light traps,cage traps,roach pastes and night traps were used to capture mosquitoes,flies,cockroaches and rodents,respectively,for density calculations. Results From 2005 to 2010,the average density of mosquitoes in Pan’an county was 2.04 per lamp-hour,with the prominent species being Culex pipiens pallens/Cx. pipiens quinquefasciatus accounting for 71.81%. The average density of flies was 1.83 per cage with Chrysomya megacephala and Musca domestica as the predominant species,which accounted for 52.62% and 37.81%,respectively. The density of cockroaches was 0.91 per paste,with Blattella germanica as the predominant species（92.10%） . The rodent density was 0.89% with Niviventer fulvescens as the predominant species（37.60%） . Most mosquitoes and flies appeared in May;the former became most active in July and the latter in June through August. Cockroaches and rats were observed throughout the year with relatively high roach density from March to October and generally peak rodent density in September. Conclusion The population composition and seasonal fluctuation of primary vectors in Pan’an county are clarified.
