ABSTRACT

Prevalence Aedes aegypti larvae and it bionomics study was conducted in Amuehtan ward in Than Lyin Township Yangon Region using non-intervention descriptive field investigation method. A total of 53 households were randomly inspected for Aedes larvae breeding water storage containers in Amuehtan ward. Aedes larvae habitats or Aedes larvae positive containers of different container categories as major, minor and miscellaneous sources and types were recorded as well as compared with each other. Aedes larvae positivity was also measured against place, condition of containers (covered or un covered). Larva indices as House Index (HI), Container Index (CI), Breteau Index (BI) and percentage of Key containers, Key premises and Pupal indices were also calculated. Result found that a total of 32(60.38%) households were found to be Aedes larvae positive in water storage containers in Amuehtan ward. Larva positivity were found 27.27% of major, 11.80% of minor and 58.33% of miscellaneous containers in Amuehtan ward respectively. In Amuehtan ward 36.11% of plastic drums in major, 33.33% paint buckets in minor, and 64.30% of discarded car tire in miscellaneous containers were found highest percentage of positive containers. Positivity of key premises was higher 10(18.87%) in Amuehtan ward although key container was found 4.79%. Larval indices such as House Index (HI) Container Index (CI) and Breteau Index (BI) were found to be 60.38%, 21.26%, and 133.96 respectively in Amuehtan ward. Pupal indices in villages were found to be highest in children 13.67 Pupae/child followed by pupae/household i.e. 7.45 in Amuehtan ward. Black and blue coloured containers, open area placed and without covered containers were found highly larval positivity. In conclusion Plastic drum, paint buckets and car tires were highly positive for Aedes larvae. Mostly plastic drum, metal drums, concrete jars, paint buckets, plastic bucket, Spirit bowls and discarded car tires were found (over 500 each larvae) key containers. Therefore, there were urgently need to control Aedes larvae in Amuehtan ward Thanlyin Township using different larval control methods as nets sweeper, chemical method as abate, larvivorous fishes which is more suitable and also need community base participation.
