中文摘要:转Bt基因抗虫棉对 3,4,5龄棉铃虫幼虫的抗性表现形式为拒食作用 ,且随幼虫龄期的增加拒食作用明显降低 ,其中对 5龄幼虫的拒食作用很低。取食Bt棉后 ,3 ,4,5龄棉铃虫幼虫中肠消化酶比活力均较对照有所减退 ,且随幼虫龄期的增加减退率明显降低 ,其中对 5龄幼虫减退率最低。由此
英文摘要:Bt transgenic cotton had anti-feeding activity to the 3rd, 4th, 5th instar larvae of cotton bollworm and the activity reduced significantly with the increase of larvae instar, among them the activity to the 5th instar larvae is very poor. The activities
