摘要：

通过离体酶活性测定，研究取食苜蓿、苋菜、生菜、白菜、玉米5种寄主植物对甜菜夜蛾磷酸酯酶、谷胱甘肽-S-转移酶和乙酰胆碱酯酶活性的影响。结果表明甜菜夜蛾取食寄主植物后，体内磷酸酯酶、谷胱甘肽-S-转移酶和乙酰胆碱酯酶活性均发生变化。除取食苋菜的甜菜夜蛾碱性磷酸酯酶活性与取食苜蓿、白菜的之间差异不显著外，其它各处理之间差异均显著。其中玉米对这3种酶的诱导能力最低。

Abstract:

The effect of host plants，including alfalfa，amaranth，lettuce，cabbage，corn，on activity of acid phospholipase，alkaline phospholipase，glutathione-s-transferase and acetylcho linesterase in beet army，Spodoptera exigua was studied. Results showed that significant activity changes of acid phospholipase，alkaline phospholipase，glutathione-s-transferase and acetylcho linesterase were found in Spodoptera exigua larvae feeding on different host plants. The others have marked difference between one another except no difference on activity of basic phospholipase between feeding on amaranth and feeding on alfalfa，cabbage.
