Abstract

This study had been carried out in order to measure the efficacy of crude hot aqueous and alcohol exracts for leaves of Adhatoda vasica at 2500 , 2000 , 1500 ppm on nymphs and adults of Ommatissus Lybicus.Also, It was fownd that , the
alcohol extract gave killing percent age 100% on adults after three days at 2500 ppm were the hot aqueous extract gave Killing percent 100% on adults after one week from treatment at 2500 ppm the alcohol extract gave a killing 96% on nymphs at 2500 ppm after one week from treatment and the hot aqueous extract gave higher percent age 84% at 2500 ppm after one week from treatment .
