全面评价了亚致死剂量吡虫啉和吡蚜酮对褐飞虱繁殖力和生存力的长期影响。毒力测定结果显示,吡虫啉和吡蚜酮对褐飞虱3龄若虫的LC_(50)分别为42.41mg/L和396.46mg/L,吡虫啉毒力约是吡蚜酮毒力的9.35倍。通过建立褐飞虱在吡虫啉和吡蚜酮亚致死剂量(LC_(30))作用下的生命表,发现褐飞虱在两种药剂处理下生物适合度都有所下降,分别为对照试虫的83.8%和8.4%。吡虫啉处理试虫仅羽化率明显低于对照,而吡蚜酮处理试虫的羽化率、雌虫比例、雌成虫寿命和卵孵化率各参数都明显下降。亚致死剂量的吡蚜酮使褐飞虱日产卵节律和卵孵化高峰都有所推迟,这可能是吡蚜酮对褐飞虱产生取食抑制作用进而导致其生殖器官发...

Long-term influences of sublethal dose of imidacloprid and pymetrozine on reproduction and biological fitness of the brown planthopper（BPH） were evaluated. Bioassay results showed that the LCs0 values for imidacloprid and pymetrozine were 42.41 mg/L and 396.46 mg/L, respectively, suggesting imidacloprid was approximately 9.35 times more toxic than pymetrozine. The effects of the sublethal dose （LCs0） of imidacloprid and pymetrozine on the fitness of the brown planthopper were evaluated by constructing and comparing the life tables. Results ...
