Abstract

Several tris-substituted derivatives of phosphoric acid synergized the toxicity of malathion to resistant houseflies and mosquitoes. In some tests it was possible to overcome acquired resistance completely. The synergists had much less effect on the toxicity of malathion to susceptible strains of the same species.
