Bacillus thuringiensis spp. israelensis and Control of Aedes aegypti Invasive Mosquitoes Species in Ecosystems

Abstract

The review presents materials on microbiocontrol of vector mosquitoes using entomopathogenic bacteria Bacillus thuringiensis ssp. israelensis (Bti). Control of invasive ectoparasites is a major health issue, as mosquito species are capable of transmitting diseases, including extremely dangerous human and animal infections (malaria, tularemia, yellow fever, hemorrhagic fevers, dengue fever, taiga (or tickborne) encephalitis, filariasis, Ku fever, cattle anaplasmosis and many other infections and invasions). Bti is considered worldwide as a promising microbial agent that combines targeted efficacy in protective measures and environmental safety. The study of the effect of Bti δ-endotoxins on the intestinal epithelium of Aedes genus mosquitoes, search and characterization of specific receptors are extremely important for understanding the mechanism of action and activity of entomocidal proteins, the basis of the pathogenic effect of polytypic B. thuringiensis. Synergism, a combination of selective larvicidal action of natural Bti strains in combination with strategies of resistance emergence preventing demonstrate a wide range of possibilities of their use and unique evolutionary features of this endospore-forming bacterium as a modern larvicidal agent against Aedes aegypti population.
