The present research is aimed to investigate the susceptibility of Cx. quinquefasciatus larvae (2nd and 4th instars), pupae and adults during exposure to various concentrations of C. nardus n-hexane extract. Increase in mortality of larvae and pupae was observed with increase in concentration of the extract solution (R2>0.90). LC50 values of extract for 2nd and 4th instar larvae were 451.8 and 599.6 ppm, respectively. The LC
