The larvicidal efficiency of acetone, petroleum ether and ethyl acetate extracts of Jatropha curcas (L.) was investigated against three different mosquito species viz., Culex quinquefasciatus, Aedes aegyptii and Anopheles stephensii under controlled conditions. The solvent extracts at 200, 400, 600, 800 and 100 concentrations have influenced varied level of larvicidal activity against the tested mosquito species. The acetone extract @ 1000ppm have demonstrated the higher level of larvicidal activity (90.00%) than the petroleum ether extract and ethyl acetate extract at the same concentration against Cu. quinquefasciatus, Ae. aegyptii and J. curcas. The estimated LC50 value assessed from the graded concentrations of acetone, petroleum ether and ethyl acetate extracts of Jatropha curcas against Culex quinquefasciatus, Aedes aegyptii and Anopheles stephensii have also demonstrated that the acetone extract was superior than other solvent extracts. The estimated LC50 exerted by acetone solvent extract against Cu. quinquefasciatus, Ae. aegyptii and J. curcas was 440.42, 445.12 and 469.21 ppm respectively which was the lowest values than the estimated LC50 exerted by petroleum ether and ethyl acetate extracts.
