为探讨麦二叉蚜Schizaphis graminum(Rondani)对吡虫啉的抗性风险和生化机理,在室内经吡虫啉多代胁迫后,分析室内麦二叉蚜种群对吡虫啉的耐受性水平及其体内酯酶对杀虫剂的响应.结果表明,经致死中浓度吡虫啉连续胁迫麦二叉蚜10代后,麦二叉蚜对吡虫啉的敏感性显著降低,其LC50值为室内对照种群的5.29倍.方差分析表明吡虫啉对麦二叉蚜连续处理后其酯酶比活力与对照种群无显著差异,但其体内可溶性蛋白质含量显著增高,且不同处理种群对吡虫啉的LC50值与其蛋白质含量呈显著正相关.经致死中浓度吡虫啉的连续多代胁迫,麦二叉蚜种群对吡虫啉的耐受性水平逐渐升高,其酯酶活性无明显变化,但可诱导体内可溶性...

In order to explore the resistance risk and biochemical mechanism of Schizaphis graminum(Rondani)to insecticides,the tolerance level and response of esterase activities to the imidacloprid were assessed after multiple generations of S.graminum have been exposed to the imidacloprid stress.After continuous stress with imidacloprid for ten generations,the sensitivity of S.graminum to imidacloprid significantly decreases with a 5.29-fold of LC50 value higher than that of the control population.Analysis of variance displays that there is no significant difference for the esterase activity between t...
