Abstract
The cotton bollworm, Heliothis zea (Boddie), was reared in environmental chambers on artificial diet and a wild host plant, Carolina geranium, Geranium carolinianum, L. at temperatures from 15.5 to 35°C. All above-ground plant parts were used by the larvae, and fruiting structures were not necessary for development to the pupal stage. Bollworms developed on plant bouquets at a rate very similar to that achieved on artificial diet but pupal weight, percent pupation, and percent adult emergence were lower in pupae produced on plant bouquets. Developmental rate parameters estimated for the combined data closely resemble previously published reports in the literature.
