摘　　要：目的了解南阳市传疟媒介。方法2005-2017年,选择南阳市唐河县马振扶乡和桐柏县淮源镇作为疟疾媒介监测点,采用夜间室外半通宵人诱法和清晨帐内捕蚊法进行传疟媒介调查。结果2005-2017年,南阳市2个监测点室外半通宵蚊帐内人诱法捕获中华按蚊平均密度为0.65~22.30只/(人·h),密度高峰为6、7月;仅2008-2011年在桐柏县捕获嗜人按蚊,平均密度为0.03~1.10只/(人·h)。2005-2011年,南阳市2个监测点清晨帐内捕蚊法捕获中华按蚊平均密度为0.08~0.24只/(顶·夜),密度高峰为每年7、8月;仅在桐柏县捕获到少量嗜人按蚊,平均密度为0.01~0.02只/(顶·夜)。结论南阳市存在中华按蚊和嗜人按蚊两种传疟媒介,中华按蚊为优势蚊种。Objective To investigate the malaria vectors in Nanyang City.Methods Two townships were selected as malaria vector surveillance sites in Nanyang City from 2005 to 2017,including Mazhenfu Township in Tanghe County and Huaiyuan Township in Tongbai County,and the malaria vectors were investigated using the semi-overnight human baiting trapping method and mosquito trapping in nets.Results The mean density of Anopheles sinensis was 0.65 to 22.30 mosquitos/(person·hour)in the two surveillance sites in Nanyang City using the human baiting trapping method from 2005 to 2017,and the peak density was detectedinJuneandJuly.An.anthropophagus was captured only in Tongbai County during the period between 2008 and 2011,with a mean density of 0.03 to 1.10 mosquitos/(person·hour).The mean density of An.sinensis was 0.08 to 0.24 mosquitos/(net·night)using the mosquito trapping in nets from 2005 to 2011,and the peak density was detected in July and August,while few An.anthropophagus captured only in Tongbai County,with a mean density of 0.01 to 0.02 mosquitos/(net·night).Conclusion There are malaria vectors in Nanyang City,including An.sinensis and An.anthropophagus,and An.sinensis is the dominant mosquito species.
