We used stacked GM maize expressing lepidopteran active Cry1F, Cry1A.105, and Cry2Ab2 proteins to explore the synergic effect on Spodoptera littoralis (Boisd.). Stacking of three Cry proteins cause high mortality to S. littoralis (98% mortality for first, second, and third instar) in contrast to sublethal effects of GM maize expressing single Cry proteins. All Cry proteins were diluted when transferred from maize to S. littoralis. Cry1A.105 was the least reduced Cry protein detected in S. littoralis while Cry2Ab2 was the most diluted Cry protein despite the fact that it was the most expressed Cry protein in leaves.
