Abstract: Escalating population of Aedes aegypti may lead to cause Dengue. However, controlling their larvae by using conventional techniques like insecticides, mosquito repellents are hazardous for human health and environment. Hence, it is recommended to biologically control the mosquito larvae through ornamental fish as they are eco-friendly and cost effective. In the present study, consumption rate of Aedes aegypti larvae and other food preference of six fishes (Angel fish, Betta fish, Gold fish, Red swordtail, Molly fish and Guppy) have been observed and a comparative study has been recorded. Angel fish and Gold fish show good efficacy towards all three types of food whereas Molly fish, Fighter and Guppy exhibit good efficacy towards Aedes aegypti larvae than the rest two food items, only Red swordtail showed significant deviation in results. So, in near future these fishes can be considered as effective biological agents for controlling Aedes aegypti Larvae.
