摘　　要：目的了解广东省西尼罗病毒潜在蚊媒致乏库蚊的构成比及密度消长情况,为及时有效地切断西尼罗病毒病的传播途径提供科学依据。方法 2009-2012年在广东省各地级市采用诱蚊灯法开展监测,对捕获的蚊虫进行鉴定及计数。结果致乏库蚊在广东省蚊虫构成中占的比例最大,占捕蚊总数的93.15%,其密度高峰在4-5月份,2009-2012年各年的平均密度分别为21.8、15.2、10.3、9.7只/灯,呈逐年下降的趋势;生境中以生畜棚中的密度最高。结论致乏库蚊是广东省的优势蚊种,加强监测可以掌握其消长规律,为制定适宜的防制措施和预警其可能的传播提供科学依据;致乏库蚊是否为西尼罗热传播媒介还需进一步研究。Objective To study the community structure and dynamic of Culex pipiens quinquefasciatus,the potential vector of West Nile Virus （WNV） disease,in Guangdong and provide scientific evidence for further development of control and prevention strategies.Methods Mosquito density was monitored by light-trap from 2009 to 2012,in Guangdong cities.Results Culex pipiens quinquefasciatus accounts for 93.15%,the largest proportion of mosquitoes.The average densities of Culex pipiens quinquefasciatus from 2009 to 2010 were 21.8,15.2,10.3,and 9.7 （light·hour）,respectively,showing a decreasing trend.The seasonal peak of density was from May to July.Of all habitats,the density in the barn was the highest.Conclusion Culex pipiens quinquefasciatus was the predominant mosquitoe species in Guangdong province.The monitoring data could provide scientific basis for the development of control strategies and warning and forecasting of WNV.But whether Culex pipiens quinquefasciatus is the West Nile fever vector needs further investigation.
