Abstract

Mosquito borne diseases are a major public threat especially in Tropical countries including Sri Lanka. Therefore mosquito larval survey may directly contribute to the prevention of mosquito vector borne diseases. In the present study mosquito larval survey was carried out in selected rural and urbanized habitats in Southern Sri Lanka for 9 months to study the availability of mosquito larvae with reference to the physical and chemical characters of the selected habitats. Availability of larvae, abundance of larvae and correlation between larvae abundance and physico-chemical characters were determined. Found mosquito larvae were identified to the genus taxonomic level using pictorial keys. There is a significant difference1 between the variation of chemical characters of pH, Conductivity, nitrate and phosphate concentration. Mosquito larvae abundance 50%, 34%, 9% and 7% in Kirala Kele, Bandaththara, Nupe and Thudawa respectively. pH of the water body negatively correlated with larval abundance. All recorded mosquito genus were Culex, Aedes, Mansonia, and Anopheles. Identifying KiralaKele as a well habitat for mosquito may lead to carry out more future research on mosquito larval survey in rural, abandoned area.
