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.
