Abstract
Development of 2 strains of the bollworm, Heliothis zea (Boddie), one from Tifton, GA and the other from Tucson, AZ, on 3 diets was similar at 12 constant temperatures between 15.6 and 34°C. Larvae developed most rapidly when they were fed a semisynthetic diet and more rapidly on corn than on cotton. Pupal development was similar for the 2 strains and the 3 foods. Duration of the adult stage of both sexes was determined at 6 constant temperatures between 15.6 and 36°C.
