摘　　要：通过对生产中常用7种杀螨剂的田间药效试验,筛选出防效好、既有良好的速效性又具持效性的杀螨剂为1.8%阿维菌素EC、15%哒螨灵EC、5%唑螨酯SC,药后30d对苹果山楂叶螨防治效果分别为95.5%～96.4%、90.2%～96.0%、90.4%～96.2%;而20%四螨嗪EC及5%噻螨酮EC的药效发挥较慢,可在山楂叶螨发生早期或密度较低时使用。Field efficacy of seven species of common acaricides against Tetranychus viennensis Zacher was determined. The results indicated that abamectin 1.8% EC, pyridaben 15% EC, fenpyroximate 5% SC, after spraying within 30 days, the control effects to Tetranychus viennensis Zacher were 95.5 to 96.4%, 90.2 to 96.0% and 90.4 to 96.2%, respectively. Active speed of clofentezine 20% EC and hexythiazox 5% EC against Tetranychus viennensis Zacher was slower, may use it in the early stage or low density.
