南京农业大学植物保护学院研究人员近期对河北邢台和江苏南京地区棉蚜进行了抗性监测,他们以用药水平最低的新疆南疆种群作为相对敏感种群,通过室内毒力测定、离体酶活力测定、相对表达量分析,研究3个地区棉蚜对丁硫克百威和吡虫啉潜在的代谢抗性机制。研究结果显示,河北邢台和江苏南京地区的棉蚜对丁硫克百威仍处于敏感阶段,但对吡虫啉的抗性已有所发展,抗性水平分别为
Plant Protection College of Nanjing Agricultural University recently conducted a survey of resistance to cotton aphids in Xingtai of Hebei Province and Nanjing of Jiangsu Province. Using the lowest population level of Xinjiang southern Xinjiang population as a relatively sensitive population, through indoor toxicity determination, in vitro enzyme activity determination , The relative expression analysis of the potential metabolites of cotton aphid to carbothuric and imidacloprid in three areas. The results showed that cotton aphid in Xingtai of Hebei Province and Nanjing of Jiangsu Province was still sensitive to carbosulfotin but its resistance to imidacloprid had been developed. The resistance levels were
