| 摘 要： | 应用酶活力测定的方法,研究朱砂叶螨经阿维菌素和高(低)温处理后对其体内自由基(O2.-)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和过氧化物酶(POD)活性的影响。结果表明,朱砂叶螨经阿维菌素处理后,两种群体内的O2.-含量急剧升高,药后4h抗性种群和敏感种群O2.-含量分别是对照的3.42、3.54倍,同时SOD、CAT活性也明显高于对照;处理组中抗性种群体内O2.-含量低于敏感种群,SOD、CAT活性高于敏感种群。不适宜的高温和低温均能使朱砂叶螨体内的O2.-、SOD、CAT、POD活力升高,敏感种群在42℃的热激下SOD、CAT、POD的活性达到最大,分别是对照的4.25、2.06、1.81倍,与其它温度处理差异显著(P<0.05),其后呈下降趋势,而抗性种群酶活性在实验温度下,始终保持平稳上升的趋势;酶活性变化率分析结果显示,SOD对热胁迫的应激性最强,CAT次之,POD最小,抗性种群三种酶活性的变化率均大于敏感种群。
