棉蚜(Aphis goosipii Glover)是我国棉花主要害虫之一,长期以来由于大量使用有机磷农药,早在1960年龚坤元等发现了棉蚜对有机磷的抗性现象,以后并对它的生化机理作过研究。近年来为了防治有机磷抗性棉蚜,不少地区应用拟除虫菊酯类农药防治。然而由于没有正确合理使用,不少地区很快产生抗性,同时由于不同地区的用药品种和历史的差异,棉蚜对药剂的抗性也不相同,为了进一步 Cotton aphid (Aphis goosipii Glover) is one of the main cotton pests in our country. For a long time, due to the extensive use of organophosphorus pesticides, as early as 1960, Gong Kunyuan discovered the resistance of cotton aphid to organophosphorus, and later on its biochemical mechanism Study. In recent years, in order to control the aphid-resistant cotton aphid, many areas of application of pyrethroid pesticides. However, in the absence of proper and reasonable use, many areas soon develop resistance, and due to differences in the history of medicinal species and history in different areas, the resistance of cotton aphids to pharmaceuticals is also different. In order to further
