摘  要：
为合理使用杀虫剂并为贵州主要烟区烟蚜的有效控制提供依据,采用浸渍法测定了贵州9个地区34个烟蚜种群对灭多威和高效氯氟氰菊酯的抗性水平。结果表明,9个地区的烟蚜对2种药剂的平均抗性倍数分别在2.53~5.13和3.15~4.44;六盘水地区烟蚜对灭多威的平均抗性达到低抗水平,毕节、黔南、安顺、铜仁、黔东南和遵义地区的烟蚜对该药处于敏感性下降水平;9个地区的烟蚜对高效氯氟氰菊酯的平均抗性均处于敏感性下降水平。34个县市中,水城、毕节、金沙、长顺、贵定、紫云、德江7个县市的烟蚜种群对灭多威达到低抗水平,抗性倍数为5.20~8.56;紫云、盘县、兴义、镇远4个县市的烟蚜种群对高效氯氟氰菊酯达到低抗水平,抗性倍数为5.39~5.82;其余县市的烟蚜对2种药剂处于敏感或敏感性下降水平。

摘  要：
In order to provide a basis for the reasonable application of insecticides and controlling M.persicae in Guizhou province,the resistance level of 34 M.persicae field populations to methomyl and λ-cyhalothrin collected from nine districts was determined with dipping method.The results showed that compared with the susceptible strain,the average resistance ratio of aphids collected from nine districts to methomyl ranged from 2.53 to 5.13,and that to λ-cyhalothrin ranged from 3.15 to 4.44.For methomyl,the average resistance of aphids collected from Liupanshui developed to low level,and the average sensitivity of aphids collected from Bijie,Qiannan,Anshun,Tongren,Qiandongnan and Zunyi was at the decreasing level.For λ-cyhalothrin,the average sensitivity of aphids in all nine districts was at the decreasing level.In all the 34 populations tested,the resistance to methomyl of aphids collected from Shuicheng,Bijie,Jinsha,Changshun,Guiding,Ziyun and Dejiang developed to low level and the resistance ratio ranged from 5.20 to 8.56.The resistance to λ-cyhalothrin of aphids collected from Ziyun,Panxian,Xingyi and Zhenyuan developed to low level and the resistance ratio ranged from 5.39 to 5.82.The other strains were still sensitive or at the sensitivity-decreasing level to the tested insecticides.
