Different concentrations of crude and different solvents viz., n-hexane, ethyl acetate, and methanol fruit peel extracts of Citrus limetta Risso (C. limetta) were taken for investigation for larvicidal activity against Culex quinquefasciatus Say, 1823 (Cx. quinquefasciatus) mosquito species. Crude extract showed good larvicidal activity with very low concentrations against 1st - 4th instars larvae. Only 3rd instar larvae were taken for larvicidal bioassay experiments for each solvent extract. LC50 values of n-hexane, ethyl acetate, and methanol fruit peel extracts of C. limetta were 661.27, 1268, and 939.43 ppm respectively after 24 h of exposure. No mortality was observed on control treatments. Log probit analyses, regression equations, and R2 values of larvicidal bioassay experiments with crude and different solvent extracts were determined. Statistical justification was done through ANOVA analyses. Qualitative phytochemical analyses were carried out and detected different secondary metabolites. No mortality was observed on tested non target organisms.
