To determine the adulticidal and repellent activities of different solvent leaf extracts of Eclipta alba(E.alba) and Andrographis paniculata(A.paniculata) against malarial vector, Anopheles stephensi(An.stephensi)Mathods:Adultieidal efficacy of the crude leaf extracts of E.alba and.1.paniculata with five different solvents like benzene,hexane.ethyl acetate. methanol and chloroform was tested against the five to six dav old adult female mosquitoes of An.stephensi.The adult mortality was observed after 24 h under the laboratory conditions.The repellent efficacy was determined against An,stephensi mosquito species at three concentrations viz.,1.0,2.5 and 5.0 mg/cm~2 under laboratory conditions.Results:Among the tested solvents the maximum efficacy was observed in the methanol extract.The LC_(50) and LC_(90) values of E.alba and A.paniculata against adults of An.stephensi were 150.36.130.19 ppm and 285.22.244.16 ppm. respectively.No mortality was obsened in controls.The chi-square values were significant at P<0.05 lev el.Methanol extract of E.alba and A.paniculata was produce maximum repellency against An.stephensi.Conclusions:From the results it can be concluded the crude extract of E. nihil and A.paniculata was an excellent potential for controlling An.stephensi mosquitoes.

The adult mortality was observed after 24 h under the laboratory conditions. The repellent efficacy was determined against An, stephensi mosquito species at three concentrations viz., 1.0, 2.5 and 5.0 mg / cm 2 under laboratory conditions. Results: Among the tested efficacy the maximum efficacy was observed in the methanol extract. LC_ (50) and LC_ (90) values ​​of E. alba and A. paniculata against adults of An.stephensi were 150.36.130.19 ppm and 285.22.244.16 ppm. Respectively. Numerical was obsened in controls. The chi-square values ​​w ere significant at P <0.05 lev el. Methanol extract of E. alba and A. paniculata was produced maximum repellency against An.stephensi. Confc: From the results it can be concluded the crude extract of E. nihil and A. paniculata was an excellent potential for controlling An.stephensi mosquitoes.
