【摘要】 目的通过连续3年对北京市奥运场馆的主要病媒生物密度进行监测,了解奥运场馆主要病媒生物的种群分布和季节消长情况,为2008年奥运会病媒生物控制提供科学依据。方法蚊虫监测采用CO2诱蚊灯法,蝇类监测采用笼诱法,鼠类监测采用夹夜法,蜚蠊监测采用粘捕法。结果奥运场馆蚊虫的优势种为淡色库蚊,占捕获蚊虫总数的96.94%;蝇类的优势种为麻蝇亚科蝇类,占捕获蝇类总数的46.13%;鼠的优势种为小家鼠,占捕获鼠类总数的63.30%;蜚蠊的优势种为德国小蠊,在奥运场馆仅捕到该种。2008年与2006年、2007年相比,主要病媒生物密度显著下降,在奥运会期间均处于低密度水平,蚊密度下降率分别为88.57%和89.26%,蝇密度下降率分别为69.88%和81.63%,鼠密度下降率为100%,蜚蠊密度下降率为99.98%。结论北京市针对奥运会开展的病媒生物控制工作使得2008年奥运会期间主要病媒生物密度大幅度下降,实现了确保奥运会不受病媒生物危害影响的控制目标。更多还原

【Abstract】 Objective To know about the population distribution and seasonal fluctuation of main vectors by the successive monitoring from 2006 to 2008 in Beijing Olympic venues,and to provide the scientific basis for vector control.Methods The CO2 trapping lamp method was used for the surveillance of mosquitoes,baited cage trapping method for the flies,night trapping method for rats and paste catching method for cockroaches.Results Culex pipiens pallens was the dominant species of mosquito,accounting for 96.94% of the caught mosquitoes in Beijing Olympic venues.The dominant species of fly was Sarcophaginae,accounting for 46.13 % of the caught flies.Mus musculus Linnaeus was the dominant species of rats,accounting for 63.30 % of the caught rats.Blattella germanica was the dominant species of cockroaches,and all the captured cockroaches were German cockroaches.Compared with 2006 and 2007,the density of main vectors decreased significantly in 2008.During the period of the Olympic Games,the density of main vectors had been in the low level.The density of mosquito declined 88.57% and 89.26%,69.88% and 81.63% for the fly density,100% for the rat density and 99.98% for the cockroach density.Conclusion The density of main vectors decreased significantly during the period of Beijing Olympic Games.No serious harmful events caused by vectors occurred in Beijing 2008 Olympic Games.The goal about vector control had been realized completely.更多还原
