EFFECT OF DIFFERENT DOSE OF BUPROFEZIN UNDER DIFFERENT MODE OF TREATMENT ON BIOMASS ACCUMULATION IN LARVAL OF PERICALLIA RICINI FAB

Abstract

On the 15 th day, the larva not treated earlier at adult stage, had more weight (110.94mg) than that of the larva obtained from adults treated only with any of the concentration of the buprofezin (P<0.01). Under this method of treatment, the larval biomass varied from 21.02 to 72.14 mg among different concentration of the insect growth regulator and it was reduced with the increasing strength of the insect growth regulator. The analysis of variance showed that it was affected by the strength of the insect growth regulator (P<0.01).
