摘要:

通过野外调查并进行方差分析发现,大石早生等4个李品种受李实蜂危害程度存在显著差异。对取食4个品种李果实的李实蜂幼虫进行羧酸酯酶、谷胱甘肽-S-芳基转移酶活力测定,结果表明:不同品种对李实蜂羧酸酯酶、谷胱甘肽-S-芳基转移酶酶活力存在显著差异;进行酯酶同工酶及过氧化物酶电泳也显示:取食不同品种李果的李实蜂酶谱有显著差异,且酶活力大小与抗虫性强弱有关系。

Abstract:

There was significant difference in damage between four varieties of plum through the methods of outside investigation and variance analysis. The enzyme assay of carboxylesterase and glutathione-S-aromatic transferase of Hoplocompa fulviconis larva feeding on four plum varieties were conducted. Results showed that there was notable difference between enzyme activity. Electrophoresis of carboxylest and peroxidase also showed the difference. Relationship was existed between enzyme activity and pest-resistance.

Key words: plum, Hoplocompa fulviconis, enzyme activity, pest-resistance
