EFFICACY OF DIOFENOLAN AT VARIOUS CONCENTRATION OF BIOMASS ACCUMULATION IN LARVAL PERIOD AGAINST BLACK HAIRY CATERPILLAR

Abstract

The black hairy caterpillar treated orally with different concentrations of the diofenolan the larval biomass on 5th day, in response to the parents’ treatment orally with different effective concentration (0.0001% to 1%) of the deiofenolan, varied from 1.86 to 4.25 mg. decreasing with the increasing concentration. The larval biomass on 10th day, showing a tendency towards decrease with the advancing concentrations, varied from 7.92 to 16.14 mg. it differed with the concentration of the diofenolan (P<.01).
