摘要: 研究了浙江田间转cry1C基因水稻T1c\|19和转cry2A基因水稻T2A\|1对靶标害虫二化螟和稻纵卷叶螟的抗性及对主要非靶标生物的影响。结果表明,与非转基因亲本对照明恢63相比,这两种转Bt基因水稻在整个生育期对稻纵卷叶螟、二化螟都具有极强的抗性,稻纵卷叶螟卷叶率减少98%以上,二化螟枯心/白穗率减少87%以上;而对非靶标害虫稻飞虱以及稻田主要捕食性天敌蜘蛛和黑肩绿盲蝽数量均无显著性影响。

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
