In lab bioassay experiment, field collected medium to large sized (3rd, 4th and 5th instar) larvae were tested to the three concentrations (low 11.25 ppm, medium 22.50 ppm and high 33.75 ppm) of Deltaphos. In all sets of experiments untreated check gave significantly lower mortality than all the concentrations of insecticides. In topical treatment experiment, higher (33.75 ppm) and medium (22.50 ppm) concentrations resulted in higher mortality of test insects than lower concentration (11.35 ppm). Similarly results were obtained in stomach poisoning experiment; however, contact poisoning experiment gave an equal mortality percentage (60 percent) in all concentration tested. Deltaphos 10+350 EC proved as an active insecticide.
