１９９６～１９９７年应用玻片浸液法测定了螨克、克螨特、三氯杀螨醇、螨死净对宁夏永宁、灵武、中卫、彭阳４县果园山楂叶螨的ＬＣ５０，测定结果表明：２％螨克乳油、７３％克螨特乳油、２０％三氯杀螨醇乳油杀螨效果较好，５％尼索朗乳油在高浓度下对成螨有一定效果，２０％螨死净水悬浮剂效果较差。试验明确宁夏山楂叶螨对５种杀螨剂均产生一定抗性，宁夏灌区的山楂叶螨抗性是山区的１．５～２．５倍。
From 1996 to 1997, the LC50 of mites, mites, dicofol and diclofen against hawthorn spider mites in 4 counties of Yongning, Lingwu, Zhongwei and Pengyang of Ningxia were determined by the slide immersion method. The results showed that: 2% Mites grams of EC, 73% mitestect EC, 20% dicofol EC kill acaricidal effect is better, 5% nisseng EC at high concentrations of adult mites have a certain effect, 20% mites dead water scavenger less effective.
