转抗虫基因植物生态安全性研究进展

Progress in ecological safety of insect-resistant transgenic plants.

转抗虫基因植物如Bt棉花等已在美国、中国和澳大利亚等国家大规模商业化种植 ,有关转抗虫基因植物潜在的生态风险已引起广泛的关注。该文综述了转抗虫基因植物研究应用现状与安全性研究进展。主要内容包括 :转抗虫基因植物的种类及其对靶标害虫的抗性 ,对非靶标害虫和天敌发生的影响 ,对农田生态系统生物多样性的影响 。

Insect resistant transgenic cotton has been planted commercially in the United States, China and Australia, and plays an important role in integrated pest management (IPM). However, concerns have been raised about the potential ecological risks of transgenic plants. This paper reviews the current status of knowledge on the development and ecological impact of insect resistant transgenic plants, with emphases on the major categories of insect resistant transgenic plants, evaluation of their resistance to insect pests, effects on non target insects and natural enemies, effects on biodiversity of agroecosystem, pest resistance management and gene flow of insect resistant transgenic plants.
