Abstract: 

Inflammatory present study is aimed to derive natural products of plant origin with insecticidal properties to control insect vectors. The aqueous, ethanol and methanol leaf extracts of the traditional mosquito repellant species, Melia dubia were evaluated against the fourth instar larvae of two mosquito species viz., Aedes aegypti and Culex quinquefasciatus. The percentage mortality of these two different mosquito species was tested after 24 hrs of exposure to different concentrations of the leaf extract. The methanolic leaf extracts showed 100% mortality at 150 ppm and the aqueous and ethanol extracts showed 65% and 75% mortality respectively. Therefore it is known that the extracts of M. dubia have prominent mosquito control property.
