TOXICITY OF VARIOUS CONCENTRATIONS OF BUPROFEZIN UNDER PUPAL DIP METHOD OF TREATMENT ON BIOMASS ACCUMULATION IN LARVA OF BLACK HAIRY CATERPILLAR. (LEPIDOPTERA: ARCTIIDAE)

Abstract

The 15 th day larvae, not treated earlier at the pupal stage, had a more biomass (110.94mg) than that treated earlier at the same stage with any concentration of the buprofezin significantly (P<0.01). As regards the effect of different concentration of the buprofezin significantly (P<0.05). The 15 th day larvae, not treated earlier at the pupal stage, had a more biomass (110.94mg) than that treated earlier at the same stage with any concentration of the buprofezin (P<0.01). As regards the effect of different concentrations on the biomass of the 15 th day larva, it decreased with increase in concentration, varying from 20.94 to 71.12mg and depended on the concentration (P<0.05).
