本研究就采自江苏省句容、南京、高邮三地褐飞虱的生物型进行了测定 ,结果表明三地稻褐飞虱类型已趋向生物型 ;采用浸苗法 ,对药剂扑虱灵进行了褐飞虱田间自然种群的抗药性监测 ,对药剂吡虫啉进行了抗药性筛选 ,对其用药安全性进行了初步评价。结果表明 ,褐飞虱对扑虱灵的抗性是 1993年的 14 .8倍 ,属中抗水平 ,且抗药性仍在上升 ;经连续筛选 8代 ,褐飞虱对吡虫啉的抗性指数为 2 .5 ,属敏感阶段
The biotypes of BPH collected from Jurong, Nanjing and Gaoyou in Jiangsu Province were measured in this study. The results showed that the three types of BPH had tended to be biotypes. Using the soaking seedling method, The drug resistance of the population was monitored, and the drug resistance imidacloprid was screened out. The safety of the drug was initially evaluated. The results showed that the resistance of the BPH to buprofezin was 14.8 times of that in 1993, which was moderately resistant and the resistance was still on the rise. After 8 generations of continuous screening, the resistance index of the BPH to imidacloprid was 2.5, Is a sensitive stage
