目的 掌握埃及伊蚊和白纹伊蚊在广东省雷州市的分布现状，评估其传播登革热和寨卡病毒病的风险。方法 2017年7-8月，利用遥感技术和地理信息系统定位，采用幼虫吸管法和诱蚊诱卵器法对广东省雷州市乌石、企水镇和沿海村落伊蚊的分布进行调查。结果 乌石镇调查了79处住宅和23艘渔船，共检出伊蚊阳性点34个，其中埃及伊蚊阳性点17个，白纹伊蚊阳性点14个，二者共生点3个；企水镇调查了55处住宅和28艘渔船，共检出伊蚊阳性点17个，其中埃及伊蚊阳性点4个，白纹伊蚊阳性点13个。流沙镇到纪家镇的15个沿海村落308处积水，未发现埃及伊蚊，检出伊蚊均为白纹伊蚊。埃及伊蚊多孳生于居民住宅和渔船的储水容器中，而白纹伊蚊主要孳生于室外容器和轮胎积水。结论 埃及伊蚊在雷州市仅分布于乌石和企水镇，并有逐渐减少的趋势；两镇的靠港大型木制渔船存在埃及伊蚊分布，是埃及伊蚊侵入的可能来源。

Objective To understand the distribution status of Aedes aegypti and Ae. albopictus in Leizhou and assess the risk of dengue and Zika virus diseases transmission. Methods From July to August in 2017, using remote sensing technology and geographic information system (GIS), the distributions of Ae. aegypti in Wushi, Qishui and coastal villages of Leizhou, Guangdong province were investigated by larval straw method and mosq-ovitrap method. Results Seventy-nine (79) residential buildings and 23 fishing vessels were investigated in Wushi and 55 residential buildings and 28 fishing vessels in Qishui. There were 34 positive places of Aedes mosquitoes in Wushi, of which 17 were positive for Ae. aegypti, 14 were positive for Ae. albopictus, and 3 were positive for both. There were 17 positive places of Aedes mosquitoes in Qishui, of which 4 were positive for Ae. aegypti and 13 were positive for Ae. albopictus. In total, 308 bodies of water in 15 coastal villages from Liusha to Jijia were investigated and only Ae. albopictus was found without Ae. aegypti. Aedes aegypti mostly breed in water storage containers of residential buildings and fishing vessels, while Ae. albopictus mostly breed in outdoor tires. Conclusion Aedes aegypti was only found in Wushi and Qishui in Leizhou, and its population and distribution range had a decreasing trend. Large-scale wooden fishing vessels in the two towns still had the Ae. aegypti distribution.
