笔者从南京农业大学获悉,近日该校植物保护学院吴益东教授课题组在棉铃虫对Bt棉花抗性研究方面取得重要进展。这是该课题组继2012年揭示棉铃虫田间种群Bt抗性遗传多样性之后的又一重要进展。为了延缓害虫对转基因Bt抗虫作物抗性的产生,美国、澳大利亚等发达国家通常采用庇护所策略,即在Bt作 The author learned from Nanjing Agricultural University recently that Wu Yidong, professor of PhD Program at the College of Plant Protection, made important progress in cotton bollworm resistance to Bt cotton. This is another important progress made by the research group in 2012 after revealing the genetic diversity of Bt resistance in the cotton bollworm population. In order to delay the pest’s resistance to the transgenic Bt insect-resistant crop, the United States, Australia and other developed countries usually adopt the shelter strategy, that is, in Bt
