Interpretive Summary: We investigated Cry1Ac levels in Bollgard® (Bt) and non-Bt cottons and their effects on pink bollworm (PBW) larval mortality. Cultivars were Delta and Pineland (DPL) 5415 RR®, NuCOTN 33B®, DPL 449 BG®/RR®. Cotton seeds were planted in six rows wide by 18 m long plots at the Western Cotton Research Laboratory, Phoenix, AZ on 21 April. The experiment was conducted as a paired plot experiment with four replications of each cultivar. Standard grower practices were used during the season and cottons, after planting, were irrigated every 14 days from 22 April to 29 August 2003.
