摘要
试验研究转Bt基因抗虫棉对非目标害虫绿盲蝽田间种群的影响结果表明,绿盲蝽在转单价抗虫棉(GK-12)与其亲本上的种群数量整个发生期无显著差异,但二代绿盲蝽对“GK-12”的危害程度大于对其亲本的危害,而对双价抗虫棉(SGK321)与其亲本的种群发生数量及其受害程度均无显著差异,“GK-12”比“SGK321”被害指数高1.27倍。绿盲蝽在单价抗虫棉“GK-12”上的发生为害有加重趋势,而在双价抗虫棉“SGK321”上的发生程度却受到一定抑制。
Population dynamics and damage of green leaf bug, Lygus lucorum Mayr, on transgenic Bt cotton are studied in this paper. The results show that the bug number on GK-12 is not significantly different from that on its parent, but its degree of leaves damaged by the second generation of green leaf bug is much higher. There are no differences between SGK321 and its parent, when the number of green leaf bug and the degree of damaged leaves are compared. The damage index of total leaves on GK-12 is 1.27 times higher than that on SGK321. Thus, the damage of green leaf bug to transgenic Bt cotton, GK-12, is upward, while the population and damage on SGK321 are controlled in some extent.
