Abstract: Objective To investigate the distribution and population density of dengue vector mosquito in 13 counties or cities of Honghe prefecture, providing scientific evidences for Aedes-borne diseases control. Methods The investigation of population density of Aedes mosquito larva was conducted using house index (HI), container index (CI), and Breteau index (BI), respectively. Results Only Ae. albopictus was found; in the residential areas, the average HI was 0.04, the average CI was 0.02 and the average BI was 4.15; the highest density in 13 counties was Kaiyuan city (20.80), the second was Honghe county (16.40). In the key locations, the HI was 0, the CI was 0.04, and the BI was 0.25; and in those of 13 counties, the highest BI was Honghe county (7.81), the second was Yuanyang city (5.56). The waste tires and buckets were the major breeding containers, accounting for 46.88% and 28.82% in total of the positive containers respectively. Conclusion Aedes albopictus is distributed in 11 counties except Lyuchun and Luxi, and in those the larval density of Kaiyuan, Honghe, Hekou, and Mile were higher. More attention should be paidby local relevant authority to prevent local dengue transmission due to the imported dengue case.

摘要： 目的 掌握云南省红河哈尼族彝族自治州（红河州）13个县（市）的登革热传播媒介伊蚊种类及其分布情况，为防控伊蚊传播疾病提供科学依据。方法 2016年7－8月在红河州居民区和特殊场所采用房屋指数（HI）、容器指数（CI）和布雷图指数（BI）调查媒介伊蚊幼蚊密度。结果 红河州仅发现白纹伊蚊；居民区HI为0.04，CI为0.02，BI为4.15；BI最高为开远市（20.80），其次为红河县（16.40）。特殊场所HI为0，CI为0.04，BI为0.25；BI最高为红河县（7.81），其次为元阳市（5.56）。伊蚊幼虫孳生容器主要为废旧轮胎和水桶，分别占阳性积水容器的46.88%和28.82%。结论 红河州13个县（市）除绿春和泸西县外，其余11个县（市）均有白纹伊蚊分布，开远、红河、河口和弥勒县（市）蚊幼虫密度相对较高，应引起相关部门重视，防止因输入性登革热病例引起本地传播。
