Biological Control of Mosquito Vectors

The main purpose of this review paper is to study different biological control methods for controlling mosquito vectors. Mosquitoes act as vector for many harmful diseases including malaria, dengue fever, yellow fever, filarial, encephalitis, chikungunya, dengue and poly arthritis. The use of chemical insecticides for controlling mosquitoes is limited because they develop resistance against these insecticides. So, efforts have been made to control the mosquito vectors by eco-friendly techniques. At present, biocontrol agents are used to control the mosquito species with the aim to reduce the impact and cost of insecticide based strategies. These biocontrol agents involve the use of natural enemies including bacteria, fungi, larvivorous fish, protozoans and nematodes. These agents target mosquitoes at different stages of their life cycle. In this paper, we focus on several bio-controlling methods used to reduce the population of mosquito vectors.
