Abstract
Satisfactory control (95%) of Schizaphis graminum (Rond.) on small grains in the Midwest area of the United States had been obtained with single spray applications of insecticides until the summer of 1974, when repeated applications and the switching of insecticides were necessary to obtain control on grain sorghum in some States. In subsequent greenhouse tests in Oklahoma on the extent of resistance, the toxicity of eight insecticides to field-collected strains from Texas, Oklahoma and South Dakota was determined. Some organophosphates (disulfoton, dimethoate, diazinon and parathion) even at a rate of 1 lb toxicant/acre failed to give satisfactory control of at least one of the strains. The data indicated that, although an insecticide-resistant biotype of the aphid had developed and some insecticides no longer gave satisfactory control, other insecticides (notably carbofuran and chlorpyrifos) showed little or no loss of effectiveness
