The field experiment was conducted for studying the efficacy of pesticides from different origin against tobacco caterpillar, Spodoptera litura (Fab.) on two cultivars of soybean crop, i.e., PK-1029 and PK-416. These included synthetic chemical insecticide, plant extract, animal origin, insect growth regulator, entomopathogenic fungi. Conventional synthetic insecticides, i. e., Triazophos was found effective against Spodoptera litura larvae followed by chitin inhibitor, i.e., Dimilin (diflubenzuron). Entomopathogenic fungi Beauveria bassiana (Dispel) showed more effectiveness than botanicals, i.e., neem seed kernel extract and animal origin pesticides, i.e., cow urine, and cow dung ash for suppressing the population of tobacco caterpillar. Dtf-_imq mltivar of sovbean was found more resistant than PK-416 against this pest.
