Abstract: Dengue vector surveillance is one of important part of vector control. The aim of this study was to determine an area at risk for dengue transmission in Sujung Village. In 100 house inspections, sampling for larval and pupal stages was done indoors and outdoors. A total of 200 ovitraps (20 ovitraps/ house) were placed indoors and outdoors of inspected houses for 5 days. To detect dengue virus in female Ae. aegypti was used Qiagen kits. The house index, container index, Breteau index were 28%, 20.7%, and 28.0% respectively. There was a statistically significant strong negative correlation between number of water-holding containers and number of larval positive containers (R =-0.66, p value = 0.000, p< 0.05). Of 200 ovitraps, 2.5% (5/200) positive ovitraps were found. No dengue virus was detected in 35 female Ae. aegypti mosquitoes. The Sujung village was an area at risk of dengue transmission.
