Abstract

Samples collected from the mangroves of Vellar estuary yielded a mosquitocidal bacterium, whose secondary metabolites exhibited mosquito larvicidal and pupicidal activity. The bacterium was isolated using standard microbiological methods and identified using classical biochemical tests. The mosquitocidal bacterium was identified as Bacillus subtilis, Bacillus thuringiensis, Bacillus sphaericus and Bacillus cereus. Mosquitocidal metabolite(s) was separated from the culture supernatant of the bacterium and its efficacy was against the larval and pupal stages of two different species of mosquitoes and determined in terms of LC50 and LC90. Mosquito larvicidal activity in terms of LC50 against Anopheleus stephensi and Aedes aegypti was 4.374 and 7.406 μl/ml and its pupicidal activity was 4.928 and 9.865 μl/ml, respectively. The present study proved that the mosquitocidal properties of the Bacillus species isolated from mangroves of Vellar estuary was evaluated as target species of mosquito vectors. This is an ideal eco-friendly approach for the vector control programs.
