| 摘 要： | [目的]通过室内抗药性筛选,比较了朱砂叶螨对植物源杀螨活性物质东莨菪内酯和螺螨酯的抗性发展差异。[结果]在70%的选择压力下,筛选18代,朱砂叶螨对东莨菪内酯的抗性系数基本没有变化。同期,对螺螨酯的抗药性发展速度较快,在相同选择压力下,筛选至14代,抗性系数达18.88。b值分析表明:这一种群中出现了抗性杂合子,而且有增多的趋势。[结论]对进一步研究东莨菪内酯的杀螨作用机理及新型杀螨剂开发具有重要的理论指导意义。

| Abstract: | [Aims]The resistance evaluations of botanical acaricidal compounds scopoletin and spirodiclofen were carried out in the laboratory in order to find out their difference.[Results] The results showed that the carmine spider mite exhibited no resistance to scopoletin by 18 generation screening.However,Tetranychus cinnabarinus produced resistance to spirodiclofen quickly,under the same selection pressure of 70% mortality,and by screening of 14 generations,resistance index reached 18.88.Analysis of b value sugge... |
