Abstract: A mosquito, deadliest arthropod vector in the world kills more than one million people every year according to the World Health Organization. It seems unbelievable that something so miniscule can kill so many people. The mission to accomplish a hit mosquito manage technique is by overcoming insecticide resistance. Mosquito borne diseases are a major life-threatening concern not only in India but across the world. The non-availability of vaccine or drugs against mosquito- borne diseases, and the limitations of traditional insecticide- based strategies have resulted in significant efforts to develop alternative eco-friendly methods. Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling, toxin producing bacteria. It is one of the best bio-larvicide for mosquitoes as there is less risk of developing a resistance towards it.
The isolates of Bacillus thuringiensis confirmed an enormous degree of variant of their larvicidal interest. L-serine minimal agar media was used to isolate Bacillus thuringiensis as it inhibits the growth of positive strains of Bacillus spp. except B. thuringiensis. This phenomenon was utilized in isolation of B. thuringiensis strains from soil. This research work provides the evidence on alternative control of mosquito which is not only eco-friendly but also has negligible risk of mosquito developing resistance towards it.
Keywords: mosquito-borne diseases, biocontrol, larvicidal, efficacy, Bacillus thuringiensis.
