The administration of penfluron and diaino-furyl-s-triazine was done by feeding and residual technique to Euproctis icilia and Euproctis fraterna larvae, to see its interaction on the experimental insects. The effect of the chemical at lethal and sublethal levels was recorded. The parameter of study was mortality, deformity, development, food consumption, growth and weight loss during exposure period. The results obtained in different experiments on these parameters were processed and are presented in tabular form. In the present study the insect growth regulators, penfluron and diamino-furyl-s-triazine, suppressed the food intake and larvalgrowth of the treated insects, both in feeding as well as residual treatment Results obtained showed that diamino-furyl-s-triazine reduced the food intake capacity more than penfluron, in third instar larvae. Reduction in food consumption was greater in Euproctis icilia than in E. fraternal in feeding treatment and was almost the same in residual treatment with penfluron. Similar results were also seen by diamino-furyl-s-triazine.
