The Entomological Society of America published a tentative method for detection for insecticide resistance in Diabrotica species (Anonymous 1972). In this publication only Diabrotica adults were used for evaluating insecticide resistance on a 24-hour basis. I began studies in 1975 to determine topical data for several insecticides on field collected larvae and adult western corn rootworms. The purpose of this research is to determine if correlations exist between adult and larval LD50 levels using organophosphates and carbamates, as well as comparisons of the larval LD50 data to field performance data.
