Summary

The joint action of several insecticide formulations with a constant concentration of the antifeedant Du-ter that gives 50% starvation with the fourth instar of Spodoptera littoralis (Boisd.) was assessed. The results provided evidence that the toxicity of all the tested insecticides to the cotton leafworm can be markedly increased by using Du-ter in combination with each of the candidate insecticides. Since Du-ter proved to be highly synergistic, its mixtures with insecticides can result in a decrease in the rate of insecticide application.
