Aedes albopictus is one of the nuisances causing mosquito in today’s world which poses a great threat to public health. Study of the breeding ground water, habitat selection and the role of algal-microbial diversity are of major importance for effective vector control strategies. Selected sites of Burdwan were surveyed throughout the year July 2014 to June 2015 in a seasonal basis and water samples were collected. After screening and isolation by serial dilution, a total of 18 bacterial isolates were found, among which KSG1, KSG2, KSG5 and BM3 were found to be prevalent throughout the year. A thorough bacterial characterization including phenotypic, morphological, biochemical, extracellular and antibiotic assay were done in order to identify the bacterial isolates at a preliminary level. Isolates were identified to be Gram positive, rod shaped bacteria resembling that of Bacillus sp. Some were spore formers too. Microbial diversity plays a major role in eliciting oviposition positive responses for the mosquitoes. Manipulating and eliminating these bacteria may serve as a tool for vector eradication.
