The Brinjal production is seriously hampered by the severe attack of whitefly (Bemisia tabaci) and Epilachna beetle. In order to control pest issue in brinjal crop botanical and conventional insecticides were used against whitefly (Bemisia tabaci) and Epilachna beetle. In present study, three natural plant extracts (@ 5% Solanum nigrum, Ricinus communis and Neem oil) and one synthetic insecticide (Imidacloprid 20 Sc) were used to evaluate the efficacy of natural plants extracts against these two insect pests of brinjal. The results indicated that all the botanical extracts and Imidacloprid significantly reduced the population of whitefly and Epilachna beetle. The mean minimum population of whitefly leaf^-1 (0.94) was observed from Imidacloprid followed by Neem oil (4.03) The lowest mean infestation (0.77) of Epilachna beetle was recorded on Imidacloprid followed by Neem oil (2.12). However, maximum percent biological efficacy against whitefly (90.21) was observed on Imidacloprid followed by Neem oil (58.19). The highest percent biological efficacy against Epilachna beetle (83.74) was observed in Imidacloprid followed by Neem oil (55.36). Furthmore, the highest yield (5308.6 kg ha^-1) was obtained from Imidacloprid treated plots followed by Neem oil (4748.2 kg ha^-1). Our results indicates that, Imidacloprid significantly showed better efficacy against whitefly and Epilachna beetle among the tested treatments, while in botanicals, Neem oil gives best result for the control of whitefly and Epilachna beetle.
