摘　　要：在不育剂筛选已获成功的基础上 ,为明确其野外应用的效果 ,应用CSⅡ不育剂可湿性粉剂在果园、桑园中分别进行山楂叶螨防治试验。结果表明 ,在果园和桑园中采用CSⅡ不育剂 10 0倍液喷雾 ,对山楂叶螨均产生明显的不育效果 ,并以桑园中的叶螨不育效果更为显著 ,其若螨、成螨和卵的总平均数量分别为 15 2 6 7头和 0 36 7头 ,而对照分别为 36 333头和 5 30 0头。Based on the success of indoor experiment on screening some chemosterilants, the tests were carried out to control the tetranychid mites, Tetranychus viennensis Zacher, in apple and mulberry gardens respectively by spraying the wettable powder of chemosterilant CSⅡ, in order to know the chemical effect in the fields. Results showed that spraying the chemosterilant CSⅡ diluted 100 times resulted in evident sterile effect. In apple garden, the average numbers of treated mites and contrasted mites were 15.267 and 36.333, respectively; in mulberry garden, the average numbers of treated mites and contrasted mites were 0.367 and 5.300, respectively. So, in mulberry garden the sterile effect of the chemosterilant CSⅡ was more evident than in apple garden.
