Abstract: Objective To investigate the distribution, seasonal fluctuation and the breeding environment of the dengue vector at the border areas of Yunnan province, and for providing the scientific basis for controlling measures of the dengue vector. Methods Collecting larvae at the habitat of 17 border cities in Yunnan province in 2016. Recording the breeding containers and identifying the fourth instar larvae at the laboratory. Calculating the Breteau index(BI), container index (CI), and house index(HI) of Aedes. Entering CI of the temporary water container and the permanent water container from 17 monitoring cities by SPSS 17.0 software. Compare t test of the two independent samples. Results In August 2016, it came out the highest results of the BI, CI, and HI which was 9.45, 4.15%, and 6.65% respectively. There was no statistical significant difference between the CI of the permanent water and the temporary water(t=-1.391, P=0.174). Aedes albopictus were distributed throughout the 17 border cities. There were Ae. aegypti populations in Gengma, Jinghong, Longchuan, Mengla, Ruili, Yingjiang, and Menghai county. Conclusion It still exists the risk of outbreak of the dengue fever in border areas of Yunnan province. Thus monitoring and controlling mosquito should be strengthened.

摘要： 目的 调查云南省边境地区登革热媒介分布、季节消长及其孳生环境情况，为制定登革热媒介控制措施提供科学依据。方法 2016年在云南省17个边境县（市）的蚊虫孳生地捞捕蚊幼虫，记录孳生容器类型，带回实验室饲养至4龄蚊幼虫进行鉴定；计算布雷图指数（BI）、容器指数（CI）及房屋指数（HI），利用SPSS 17.0软件录入2016年17个监测县（市）统计的暂时性积水容器和永久性积水容器的CI数据，通过两独立样本t检验进行比较。结果 2016年8月BI、CI和HI最高，分别为9.45、4.15%和6.65%。蚊幼虫孳生地中永久性容器和暂时性容器的CI差异无统计学意义（t=-1.391，P=0.174），17个边境县（市）均有白纹伊蚊分布，其中耿马、景洪、陇川、勐腊、瑞丽、盈江和勐海县（市）有埃及伊蚊分布。结论 云南省边境地区仍存在登革热疫情暴发的风险，应继续加强蚊媒监测和控制。
