| 中文摘要: |
| 为了探讨烟蚜对杀虫剂抗性与酶活关系，就田间烟蚜种群对乐果、灭多威和阿维菌素3 种杀虫
剂的抗性与酶活性的关系进行研究。对具有不同抗性水平的几个田间烟蚜种群的酶活性测定结果显示：抗
乐果、灭多威、阿维菌素品系中AchE、GSTs 和CAT 3 种酶的活性都高于敏感品系，其中抗乐果的兴仁和湄
潭抗性品系AchE 酶活性为敏感品系的1.212、1.588 倍，GSTs 酶活性为敏感品系的1.625、1.900 倍，CAT 酶
活性是敏感品系的1.439、2.018 倍；抗灭多威品系的清镇和湄潭抗性品系AchE 酶活性为敏感品系的1.078、
1.647 倍，GSTs 酶活性为敏感品系的 1.142、1.935 倍，CAT 酶活性为敏感品系的1.142、1.935 倍；抗阿维菌素
的兴仁和长顺抗性品系AchE 酶活性为敏感品系的1.370、1.664 倍，GSTs 酶活性为敏感品系的1.830、2.318
倍，CAT 酶活性为敏感品系的1.800 倍、3.708 倍。研究结果可为阐明田间烟蚜种群抗性产生机制提供参考。 |
| 英文摘要: |
| In order to explore the relationship between insecticide resistance and enzyme activity in natural
population of Myzus persicae（Sulzer），we studied the activities of Ache，GST and CAT in M. persicae（Sulzer）
insecticide resistance to dimethoate，methomyl and avermectins. The results showed that，the resistance stains
（different regions）of dimethoate，methomyl and avermectins had higher enzyme activity of AchE，GSTs and
CAT than susceptible strain. For the resistance stain of dimethoate，the enzyme activities of AchE in Xingren
and Meitan resistant strain were 1.212 times，1.588 times than susceptible strain；the enzyme activities of
GSTs resistant strain were 1.625 times，1.900 times than susceptible strain，and the enzyme activities of CAT
resistant strain were 1.439 times and 2.018 times than susceptible strain. For the resistance strain of methomyl，
the enzyme activities of AchE in Qingzhen and Meitan resistant strain were 1.078 times 1.647 times than
susceptible strain；the enzyme activities of GSTs resistant strain were 1.142 times，1.935 times than susceptible
strain，and the enzyme activities of CAT resistant strain were 1.142 times，1.935 times than susceptible strain. For the resistance strain of avermectins，the enzyme activities of AchE in Xingren，Changshun resistant strain were
1.370 times，1.664 times than susceptible strain；the enzyme activities of GSTs resistant strain were 1.830 times，
2.318 times than susceptible strain，and the enzyme activities of CAT resistant strain were 1.800 times，3.708
times than susceptible strain. The results provide a reference for elucidating the field resistance mechanism of M.
persicae（Sulzer）population. |
