Alternative biocontrol techniques based on botanicals are chosen over synthetic pesticides because botanicals are less prone to acquiring resistance and are more environmentally friendly. In this study, the effectiveness of Clematis gouriana (C. gouriana) against growing wrigglers of Culex quinquefasciatus (Cx. quinquefasciatus) was demonstrated. Leaves of C. gouriana were collected and fractionated using chloroform/methanol (1:1, v/v). In a dose-dependent technique, the crude and solvent extracts were tested for larvicidal activity for 72 hours. Cent percent larvicidal efficacy was found in a concentration of 5% crude and 250 ppm solvent extract, with the most effective LC50 value (22.78 ppm) against first instars. FT-IR spectrum indicated the presence of aromatics, alkanes, alcohols, amines, and amine salts in chloroform/methanol (1:1, v/v) extract. Overall, the present study demonstrated the potential of C. gouriana as a natural source for vector management programmes.
