Abstract

• Aedes aegypti is recognized as dengue fever mosquito that transmits chikungunya, zika and yellow fever. Vector surveillance is a significant tool to determine factors of related dengue transmission. Entomological survey was carried out in three different endemic areas of Monywa Township, from August 2018 to July 2019. The monthly mosquito larval survey was carried out by examining all containers present in houses of both urban and rural areas. A total of 50 houses in each locality were visited on the basis of systematic sampling method during every month. The potential breeding habitats were screened for the prevalence of Ae. aegypti larval population. A total of 1800 houses and 10405 containers were examined for breeding sites of Ae. aegypti in all seasons in the whole year. Out of these, 893 houses and 1818 containers were positive. The overall house index (HI), container index (CI) and breteau index (BI) were 49.61%, 17.47% and 101% respectively. Entomological indicators (HI, CI, BI) of Ae. aegypti larval population were above the critical level and a dynamic population of Ae. Aegypti correlated with rainfall in the study. Regular water supply system and dumping sites should be supported to all study areas. Public health education, community intervention for prevention of vector breeding, information from mass media and regular entomological survey are required to create public awareness and to control mosquito transmitted diseases.
