近日,中国农科院植物保护研究所吴孔明科研团队阐明了害虫对Bt作物抗性治理的新策略,研究成果已被国际顶尖SCI学术期刊《国家科学院院刊》(PNAS)在线发表。转Bt基因抗虫棉花、玉米和大豆已广泛种植,高效控制了靶标害虫的发生与为害,显著减少了化学农药的用量。但近年因害虫产生抗性导致防治失败的案例不断出现, Recently, Wu Kongming, a research team at the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, set forth a new strategy for pest resistance to Bt crops. The research results have been published online by the International Academic Journal of the National Academy of Sciences (PNAS). Bt transgenic cotton, corn and soybeans have been widely planted, efficient control of the target pest occurrence and damage, significantly reducing the amount of chemical pesticides. In recent years, however, there have been many cases of failure of prevention and treatment due to the resistance of pests.
