摘　　要：本文用常规生化方法研究了万寿菊的氯仿提取物在光照和非光照条件下对山楂叶螨体内几种代谢酶活性的影响 ,结果表明 :在光照和非光照条件下蛋白酶活性都受到明显抑制 ;谷胱甘肽 S 转移酶在非光照条件下被激活 ,而在光照条件下被显著抑制 ;山楂叶螨的酯酶同工酶活性在非光照条件下变化不明显 ,而在光照条件下被明显抑制。研究表明 。Tateges erecta is an useful natural plant pesticide according to the former reports.In this paper,the effects on several enzyme systems about extracts of Tateges erecta against Tetranychus viennensis Zacher were studied.The results showed that the extracts of Tateges erecta had hgih effect on Tetranychus viennensis Zacher.Different from that of the dark treated group,the activities of protease,GSTs and esterase isozyme could be strongly inhibited in light treated group.The result indicated that the extract of Tateges erecta possessed high photo-activity.
