A Review on Vector Borne Diseases and Various Strategies to Control Mosquito Vectors

Abstract

Mosquito vector transmit serious infectious diseases that include dengue, chikungunya, malaria, filariasis, leishmaniasis, Japanese encephalitis, west Nile fever, yellow fever and rift valley fever. Insecticides-based control measures have historically and currently been an important control approach against major mosquito-borne diseases. Chemical pesticides, on the other hand, are non-selective and can harm other beneficial organisms. Controlling mosquitoes with entomopathogenic bacteria is a convincing, ecologically acceptable alternative to chemical pesticides. Bacillus thuringiensis israelensis and Bacillus sphaericus are insecticidal microorganisms which are spore forming and these bacteria are the most extensively utilised alternative mosquito control agents, considering the rapid development of resistance, especially to B. sphaericus by the larvae of Culex spp. Under this circumstances, it is necessary to find an alternative biological control agents from natural resources. The present review focus mainly on the various strategies to control mosquito vectors.
