| 摘 要： | 为了解不同诱导处理与落叶松诱导抗性及广食性昆虫舞毒蛾协同抗性之间的关系,以喷施茉莉酸甲酯、茉莉酮、舞毒蛾幼虫取食和松毛虫幼虫取食4种方法处理落叶松幼苗,检验舞毒蛾幼虫取食不同处理诱导的落叶松后,其中肠酸性磷酸酯酶(ACP)、碱性磷酸酯酶(AKP)、羧酸酯酶(CarE)、谷胱甘肽S-转移酶(GSTs)4种解毒酶活性随时间的变化趋势。结果表明:取食不同处理诱导的落叶松后,舞毒蛾幼虫酸性磷酸酯酶活性均显著低于对照;取食经舞毒蛾幼虫取食诱导的落叶松后,试虫中肠碱性磷酸酯酶活性先升高后降低,除此之外,取食其他3种处理诱导的落叶松后,幼虫中肠碱性磷酸酯酶活性均受到抑制;幼虫羧酸酯酶活性也都受到不同程度抑制,与对照相比差异极显著;幼虫谷胱甘肽S-转移酶的活性,取食茉莉酸甲酯和舞毒蛾幼虫取食处理的幼苗显著低于对照,而取食另外2种处理的幼苗显著高于对照。舞毒蛾幼虫取食诱导的植物抗性,可影响同一种群后续取食者的解毒机制,这是植物抗性和昆虫种内竞争的综合表现。茉莉酸甲酯作为一种外源植物激素,可诱导植物产生抗性,且有效抑制后续取食者的解毒作用,其作用强度与作用时间与舞毒蛾幼虫取食处理极为相似。茉莉酸甲酯可作为有效的植物诱导剂,在害虫...

| Abstract: | Different induction treatments were conducted to investigate the relationship between Larix gmelinii-induced resistance and euryphage insect Lymantria dispar collaborative resistance.In this study,larch seedlings were treated with Methyl Jasmonate(MeJA) insufflation,Z-jasmone insufflation,Lymantria dispar larva feeding,Dendrolimus superans larva feeding,and the change trends of four detoxifying enzymes,i.e.acid phosphatase(ACP),alkaline phosphatase(AKP),carboxylesterase(CarE),and glutathione S-transferase(G... |
