ABSTRACT:   The study was conducted in Mingalarywarthit and Taungnar villages under Aeindu RHC, Hpa-an Township from August 2014 to October 2014 using non-intervention descriptive field investigation method. All potential breeding sites were examined in order to carry out the systematic study. Larva positive containers of different container categories as major, minor, miscellaneous containers and types were recorded. Key containers and Key premises were recorded and compared with each other. In Mingalarywarthit and Taungnar villages, 86.27% and 80% of households were found Aedes larvae positivity. The percentage positivity of larvae in major, miner and miscellaneous containers in both villages were 56.52%, 50.94%, 88% and 38.14%, 10.84%, 42.86%, respectively. The percentage positivity of Key containers and Key premises in both villages were found 7.95%, 5.83% and 19.61%, 44%, respectively. In Mingalarywarthit and Taungnar villages, the larval indices such as House index (HI), Container index (CI), Breteau index (BI) were observed 86.28%, 59.86%, 172.5% and 80%, 22.06%, 206%, respectively. Larval indices of HI and CI in Mingalarywarthit village were higher when compared with the HI and CI of Taungnar village although BI of Taungnar village was higher positivity than Mingalarywarthit village. Most of the larva positive containers were bago jars, concrete tanks, drums, car tires, bamboo stamps and man-made tree holes which were found under the roof with full rain water in wet season. Both areas are high positivity of larval indices and water storage containers. Both areas have high-risk area of DF and DHF according to Aeindu RHC records. Therefore, proper control method is needed to clean out the Aedes larvae in water storage containers to reduce transmission of DF and DHF in children.
