Mosquitoes act as a vector for most of the life threatening diseases like malaria, yellow fever, dengue fever, chikungunya ferver, filariasis, encephalitis, West Nile Virus infection, etc. Under the Integrated Mosquito Management (IMM), emphasis was given on the application of alternative strategies in mosquito control. The continuous application of synthetic insecticides causes development of resistance in vector species, biological magnification of toxic substances through the food chain and adverse effects on environmental quality and non target organisms including human health.

There are several procedures to control mosquitoes by chemical, mechanical, genetical or biological means. Biological control of mosquito larvae by the application of natural animal products is one of the important techniques, which is cheap, easy-to-use and environment friendly. (Correspondence)
