摘　　要：探讨了2种矿物油乳剂与2种杀螨剂混合使用对3种柠檬害螨的田间防效.单一用药时,15%哒螨灵乳油1000倍液对3种柠檬害螨的田间防效最差,防治后第1d、第3d及第7d田间防效均处于60%以下.混合使用时,97%法夏乐乳油50倍液+5%阿维菌素乳油1500倍液、97%法夏乐乳油50倍液+15%哒螨灵1000倍液、97%法力佳乳油200倍液+5%阿维菌素乳油1500倍液及97%法力佳乳油200倍液+5%哒螨灵乳油1000倍液防治后第3d和第7d田间防效可达到70%以上.因此,3种柠檬害螨已对哒螨灵产生了抗药性,矿物乳油与其他化学农药混用具有明显的增效作用.The containing efficacy for Panonychus citri, Eotetranychus sexmaculatus, Phyllocoptruta oleivora, were determined by 2 mineral spray oils emulsion, 2 chemical pesticides and their mixtures in lemon orchards. The field efficacies of pyridaben 15% EC(1000×) was the worst for three kinds of lemon mites, and the field efficacies on the 1st, 3rd, and 7th after treatment were below 60% when the pesticide was used alone. The field efficiencies of citrole paraffin oil 97% EC (150×)+ avermectin 5% EC (1500×), citrole paraffin oil 97% EC (150×)+ pyridaben 15% EC (1000×), mana 97% EC (200×)+ avermectin 5% EC (1500×) and mana 97% EC (200×)+ pyridaben 15% EC (1000×), their corrected mortality were more than 70% after 3 and 7 days when the pesticides were mixed. Therefore, the three types of lemon mites had resistant to the pyridaben, the mineral spray oils emulsion have a significant synergistic effect with other chemical pesticides.
