ABSTRACT:   A total of 395 and 243 houses in two selected wards of Kyimyindine and Tamway townships, respectively were surveyed for Aedes aegypti adults and larvae to obtain baseline entomological indices. Establishment of innovative larval control methods has been achieved during pilot surveys and laboratory experiments were successfully undertaken before the inter-vention. Even during the hot dry season, more than 50% of the total houses examined were found to be positive for larvae in both townships. During pre-intervention surveys, all entomological indices increased after the onset of rain. A training workshop to transfer the innovative larval control methods to the local community was held at Kyimyindine (intervention) Township. Close supervision and appropriate larval control methods were introduced in the intervention township. The methods included periodic augmentative release of larvivorous fish and dragon-fly nymphs, and use of cotton net sweepers. Post-intervention evaluations were undertaken twice per month. All indices gradually decreased to a very low level in intervention ward (Breteau Index dropped from 201 to 62). At the same time, the indices remained unchanged or were slightly above pre-intervention levels in non-intervention ward of Tamway Township (Breteau Index varied from 100 to 127). There was also a significant reduction of key premises (²= 14.49, p<0.0001) and key containers (²= 25.49, p<0.0001) in intervention ward. Regarding dengue morbidity, decrease in both clinically suspected dengue and reported DHF cases were evident at the intervention township. It showed that regular close-monitoring with active community participation is effective and is essential for prevention and control of dengue/DHF.
