ABSTRACT

Colour preference of Aedes mosquitoes on domestic used natural water storage containers survey was done in Amuehtan ward Thanlyin Township, Yangon Region in December 2018. All domestic used major, minor and miscellaneous water storage containers were inspected and recorted for Aedes larvae positivity according to natural colours of containers. Result found that a total of 334 water storage containers were inspected 12 kinds of coloured containers were observed in the ward. Of this black coloured containers were found highest distributed number 92(27.54%) followed by blue 48(14.37%), brick 46 (13.77%), darkgreen 45(13.47%) and lowest was observed steel coloured containers 3(0.9%). The highest number of larvae positivity was found in black and blue coloured containers 17(23.94%) followed by darkgreen 10(14.08%) and lowest positivity was found 1(1.41%) in red and green coloured containers. Although yellow, clear and steel containers were found larvae negative. Blue coloured containers in major (44.44%), white and brick coloured in minor (28.57% and 22.72%) and black coloured in miscellaneous containers (78.57%) were found highest larvae positivity. In conclusion black, blue, brick, white and darkgreen coloured containers were found high colour preferences of Aedes mosquitoes. Study suggested that yellow, clear, and steel coloured containers are most suitable for water storing. Other highly used water storage containers as black, blue, brick, white and other coloured containers in communities were properly covered to control breeding of Aedes mosquitoes.
