摘  要:
采用稻苗浸渍法测定了烯啶虫胺等13种药剂对褐飞虱的室内毒力。结果表明,属于超高效的杀虫剂有烯啶虫胺、氟虫腈、噻嗪酮,对3龄若虫5d的LC50分别为0.13、0.19、0.29mg/L;属于高效的药剂有吡虫啉、氯噻啉、阿维菌素、甲维盐、高效氯氰菊酯、高效氯氟氰菊酯、二嗪磷,对3龄若虫的LC50介于1~10mg/L之间;属于有效的药剂有毒死蜱、异丙威、吡蚜酮,对3龄若虫5d的LC50分别为14.68、22.13、28.07mg/L。根据药剂类型、作用方式、作用机制等,建议防治稻飞虱时首选烯啶虫胺、噻嗪酮、吡蚜酮等药剂。

摘  要:
Bioassay method was dipping seedling. Testing result showed that three insecticides were ultra-high effect,seven insecticides were high effect,and three insecticides were effect. Nitenpyram,fipronil and buprofezin were belonged to ultra-high effect,and the LC50 was 0.13,0.19,0.29 mg/L respectively. Imidacloprid,imidaclothiz,abamectin,emamectin benzoate,beta-cypermethrin,lambda-cyhalothrin and diazinon were belonged to high effect,LC50 was from 1 to 10 mg/L. Chlorpyrifos,isoprocarb and pymetrozine were belonged to effect insecticide,and the LC50 was 14.68,22.13,28.07 mg/L severally. In according with chemical structure,mode of action and biochemistry,the proposals is suggested that nitenpyram,buprofezin and pymetrozine are priority chose at controlling brown planthopper.
