中文摘要：毒力测定结果显示 ,虽然褐飞虱NilaparvatalugensSt?l田间品系对吡虫啉还没有表现出明显的抗性 ,但室内筛选品系已经出现了一定水平的抗性 ,抗性品系 1(R1)和抗性品系 2(R2)的抗性倍数分别为 25.38和 68.92。通过建立抗性品系、田间种群和敏感品
英文摘要：Although the resistance of BPH to imidacloprid was low in the field, high resistance has been observed in strains selected by imidaclop rid. The effects of the imidacloprid resistance o n the fitness of BPH were evaluated in terms of developmental and r
