摘　　要：罗宾根螨(Rhizoglyphus robini Clapareda)为危害球根作物之主要根螨种类之一。在室内条件下采用浸渍法,测定了几类常用的杀虫农药对罗宾根螨的杀伤情况,结果表明:所有杀虫螨剂中乐果效果最好,三氯杀螨醇次之,尼索朗杀成螨效果最差,而杀菌剂多菌灵与代森铵显然杀螨效果也很不好。根据农药性质及杀虫效果的不同,从中选出10种,对罗宾根螨进行毒力测定。对罗宾根螨成虫的毒力测定试验可知,乐果各稀释倍数下,效果最好。尼索朗,长丰各稀释倍数效果明显最差。Rhizoglyphus robini Clapareda was one sort of the acarus who harmed the corm crop. In the room, we used slide dip method to determine several insecticide effect for controlling Rhizoglyphus robini Clapareda. The result make clear： Dimethoate is the best among insecticides. Dicofol takes second place, Hexythiazox is the worst for killing adult acarus, Bactericide Carbendazim and Amobam are worse. According to pesticide character and effect, we selected ten sorts of pesticides to begin toxicity measure. The results pointed out：Dimethoate was the best in all dilute multiple. Hexythiazox and fenvalerate were the worst in every dilute multiple
