摘要
１９８７～１９９０年对水稻褐飞虱（Ｎｉｌａｐａｒｖａｔａｌｕｇｅｎｓ，ｓｔａｌ）的抗药性监测结果表明，褐飞虱对甲基对硫磷、马拉硫磷、杀螟硫磷产生了４．２～６．０倍的抗药性，对异丙威、西维因的抗性指数达２．５～３．４倍。选择以噻嗪酮、杀虫单为主要成分的增效复配剂，不仅能有效地控制水稻中后期多种害虫的危害，而且由于减少单剂用量，降低药剂的选择压力，达到延缓或控制抗药性产生和发展的目的。
The results of insecticide resistance monitoring for Brown Planthopper ( Nilaparvata lugeus , stal) during 1987￣1990 indicated that Brown Planthopper had developed 4 2￣6 0 folds of pesticide resistence to Methamidophos, Malathion and Methyl parathion, and 2 5￣3 4 resistance index to Isoprocarb and Carbaryl The mixture which was composed of Shachongdan and Buprofezin had been selected This mixture can not only control several pests effectively which damage rice in the middle and later stage, but also can reduce the dosage of single components and lower the pressure of selection to pests The utilization of the mixture can delay or regulate the proceed and development for pesticide resistance
