ABSTRACT

 

Phytochemicals especially eco friendly brands are deemed as the need of the day as the synthetic chemicals cause multifocal hazards to the very life and environment. Emergence of new strains of pathogens as well as vectors with alarmingly increasing resistance makes the situation more vulnerable. The present endeavour is to assess the larvicidal ability of aqueous extract of 22 ethnical plants which are widely used as mosquito repellents in different regions of Kerala, India. Among plants under experimentation Azadirachta indica, Ocimum gratissimum and Gliricidia sepium are most effective. The results would surely have an impact on boosting research aiming at evolving a new methodology to control mosquito menace.
