麦长管蚜、禾谷缢管蚜、麦二叉蚜和麦蚜是世界性的重要害虫。本研究测定了4种麦蚜对7种杀虫剂的敏感性。此外，羧酸酯酶（CarE），谷胱甘肽S-转移酶（GSTs），细胞色素P450单加氧酶（P450）的活性测定在吡虫啉处理和未处理的蚜虫。结果表明，四种麦蚜对供试药剂的敏感性不同，麦长管蚜对药剂的敏感性不同。地罗丹对大多数杀虫剂表现出更高的耐受性。CarE和GST活性在M. dirhodum和P450 s活性显著增加。氧化酶抑制剂增效醚可提高稻瘟病菌对吡虫啉的敏感性。dirhodum（20倍）。这些结果表明，P450在吡虫啉代谢过程中可能起重要作用。迪若丹我们认为，一个高度物种特异性的方法是必不可少的管理M。迪若丹
Sitobion avenae (Fabricius), Rhopalosiphum padi (Linnaeus), Schizaphis graminum (Rondani), and Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) are important pests of wheat and other cereals worldwide. In this study, the susceptibilities of four wheat aphid species to seven insecticides were assessed. Furthermore, the activities of carboxylesterase (CarE), glutathione S-transferase (GSTs), and cytochrome P450 monooxygenase (P450s) were determined in imidacloprid treated and untreated aphids. The results showed that the susceptibilities of four wheat aphid species to tested insecticides are different and M. dirhodum has shown higher tolerance to most insecticides. Relatively higher CarE and GST activities were observed in M. dirhodum, and P450s activities increased significantly in response to imidacloprid treatment. Moreover, susceptibility to imidacloprid were increased by the oxidase inhibitor piperonyl butoxide in M. dirhodum (20-fold). The results we have obtained imply that P450s may play an important role in imidacloprid metabolic process in M. dirhodum. We suggest that a highly species-specific approach is essential for managing M. dirhodum.
