The laboratory experiment was carried out during March to April of 2014 in the laboratory of entomology, Sam Higginbottom Institute of Agriculture Allahabad, India. The botanical extracts that include Neem, Sarifa and bioagent Beauveria bassiana and Insecticide (Cypermethrin 0.07%) with treatment of Control in a randomized block design (RBD) were tested against caterpillars of Spilosoma obliqua on cabbage leaves in plastic jars. Cypermethrin significantly increased population reduction of Spilosoma obliqua (100%) followed by leaf extracts of Neem (90.00%), Sarifa (83.33%) and Beauveria bassiana (73.33%) as compared with Control (0.00%), pupae did not appear during treatment of Cypermethrin 0.00% with significantly reduced from other treatments Neem 10.00%, Sarifa 16.67%, B. bassiana 26.66% and Control 100.00% at 10% concentrations after 35 days
