【摘要】 通过测定与烟蚜抗药性相关的解毒酶 (α -NA羧酸酯酶、β-NA羧酸酯酶、谷胱甘肽转移酶和酸性磷酸酯酶 )和靶标酶 (乙酰胆碱酯酶 )的活力 ,比较了云南 7个主要烟区田间烟蚜种群的酶活力差异 ,发现不同烟区烟蚜酶活力差异极显著 ,5种酶的活力均以曲靖马过河种群最高 ,丽江斜阳种群最低更多还原

【Abstract】 The activity of the detoxicating enzymes related to pesticide resistance in Myzus persicae (α-NA carboxylesterase,β-NA carboxylesterase,glutathione transferase and acid phosphatase) and the target enzyme (acetylcholinesterase) was determined. A comparison of the enzyme activity between the field populations of the pest in 7 major tobacco- producing areas in Yunnan revealed a highly significant difference in the enzyme activity of M. persicae in different areas. The activity of all the 5 enzymes studied was highest in Maguohe population of Qujing and lowest in the Xieyang population of Lijiang.更多还原
