Abstract: Effects of Bt rice T1c\|19 (cry1C) and T2A\|1 (cry2A) on the resistance of target pests (Chilo suppressalis Walker and Cnaphalocrocis medinalis Guenee) and non\|target pests was evaluated in Zhejiang field. The results showed that T1c\|19 and T2A\|1 Bt rice could be high resistant to C. suppressalis and C. medinalis. The damage caused by C. medinalis and C. suppressalis on T1c\|19 and T2A\|1 decreased up to 98% and 87%, respectively; and there was no significant effect on non\|target pest, i.e. rice planthoppers, and natural enemies, i.e. spiders and mired bugs

Key words: Bt transgenic rice, arthropod, target resistance, non\|target, Zhejiang field
