摘　　要：瑞香狼毒的氯仿、石油醚、甲醇提取物对果树重要害螨山楂叶螨有很好的内吸和触杀活性 ;对氯仿提取物处理后的成螨体内几种重要酶系活性测定发现 ,在内吸处理中 ,其对蛋白酶、谷胱甘肽 S 转移酶 ,酯酶同功酶有不同程度的激活作用 ;在触杀处理中 ,对蛋白酶、谷胱甘肽 S 转移酶影响不明显 ,对酯酶同功酶有一定的抑制作用 ;研究表明 ,瑞香狼毒可以有效杀死山楂叶螨 ,是一种很有利用价值的杀虫植物。The insecticidal activities of the four different extracts from a novel pesticidal plant? 玈telera chamaejasme L. were studied. Three kinds of important enzyme systems of Tetranychus viennensis Zacher were tested. The results indicated that the extracts of S.chamaejasme had strongly pesticidal activities against T.viennensis. At the same time, when contacting with the extract in chloroform, the activities of protease, glutathione S transferase and esterase isozyme in T.viennensis were induced, but when feeding with the leaves absorbing the extract in chloroform, the activities of protease and glutathione S transferase in T.viennensis were not very clearly effected, but that of esterase isozyme was inhibited.
