BACKGROUND: We aimed to extract the ingredients from leaves of @entity2708 (Bt @entity2708 ) using different solvents and evaluate for potential use to control different larval stages of mosquito species, @entity4224 and Anopheles stephensi. METHODS: Qualitative and quantitative estimation of ingredients from Go. hirsutum (Bt) plant extract was carried out and their inhibitory action against mosquito larvae was determined using mosquito larvicidal assay. RESULTS: LC50 values of water, @entity1068 , @entity1046 and @entity4315 extracts for Ae. aegypti were 211.73  21.49, 241.64  19.92, 358.07  32.43, 401.03  36.19 and 232.56  26.00, 298.54  21.78, 366.50  30.59, 387.19  31.82 for 4(th) instar of An. stephensi, respectively. The water extract displayed lowest LC50 value followed by @entity1068 , @entity1046 and @entity4315 . Owing to the comparatively better activity of water extract, its efficacy was further evaluated for mosquito larvicidal activity, which exhibited LC50 values of 133.95  12.79, 167.65  11.34 against 2(nd) and 3(rd) instars of Ae. aegypti and 145.48  11.76, 188.10  12.92 against 2(nd) and 3(rd) instars of An. stephensi, respectively. Crude protein from the water extract was precipitated using @entity1324 and tested against 2(nd), 3(rd) and 4(th) instars of Ae. aegypti and An. stephensi. It revealed further decrease in LC50 values as @entity71530 (nd), 3(rd) and 4(th) instars of Ae. aegypti and An. stephensi, respectively. CONCLUSION: Leaves extracts of Go. hirsutum (Bt) is potential mosquito larvicide and can be used as a potent alternative to chemical insecticides in integrated pest management.
