Role of ornamental fishes to control Aedes albopictus larvae population

Abstract

Aedes albopictus is a potential vector that is responsible for severe outbreaks of dengue and DHF. Implementing traditional methods such as insecticides and mosquito repellents are harmful to the environment and to human health. In the present study, the rate at which Aedes albopictus larvae were consumed as well as the other feeding preferences of five ornamental fishes (Guppy, Molly fish, Betta fish, Gold fish, and Angel fish) were noted and compared. While Molly fish, Fighter, and Guppy considerably prefer Aedes albopictus larvae over the other food item, Gold fish and Angel fish exhibit good efficacy toward both types of food. In the last decade of little works (use of ornamental fish) have been done to control Aedes mosquito population. Therefore, a preliminary attempt has been undertaken to include ornamental fishes as vector controlling agent.
