The present experiment was conducted in the laboratory of Department of Entomology, College of Agriculture, Gwalior (M.P.) during Kharif season in the year 2019-20. Five different insecticides and one control were selected for the experiment to test their efficacy against Bihar hairy caterpillar Spilosoma oblique Walker. The experiment was carried out in completely randomized block design (CRD). All the treatments were replicated four times. Observations were recorded 12, 24 and 48 hrs after insecticides application. The sample consisted of 24 caterpillars of S. obliqua per replication. Emamectin benzoate 5% SG @ 0.44 gm/lit. showed the best results after 12, 24 and 48 hours after application. All the treatments were found superior over control.
