【摘要】 经鉴定,福建省蝴蝶兰上的红蜘蛛为太平洋伪叶螨(Tenuipalpus pacificus Baker)。在大棚中测定了15%苯丁·哒螨灵乳油(1500倍液)、45%石硫合剂结晶(150倍液)、73%炔螨特乳油(2000倍液)、1.8%阿维菌素乳油(2000倍液)、20%甲氰菊酯乳油(1500倍液)、20%三唑锡悬浮剂(2000倍液)和20%丁氟螨酯悬浮剂(2500倍液)7种杀螨剂对蝴蝶兰红蜘蛛的防效,结果表明:从速效性、最高防效性及持效性方面来看,15%苯丁·哒螨灵乳油、45%石硫合剂结晶、73%炔螨特乳油和1.8%阿维菌素乳油对蝴蝶兰红蜘蛛的防效最好,与其他3种杀螨剂存在明显差异。更多还原

【Abstract】 The red spider mite on butterfly orchid in Fujian province was identified as Tenuipalpus pacificus Baker. In greenhouse,the control efficiencies of 15% Fenbutatin · Pyridaben EC( 1500 ×),45% Lime sulfur JG( 150 ×),73% Propargit EC( 2000 ×),1. 8% Abamectin EC( 2000 ×),20% Fenpropathrin EC( 1500 ×),20% Azocyclotin SC( 2000 ×) and 20% Cyflumetofen SC( 2500 ×) against red spider mite on butterfly orchid were tested. The results showed that: in terms of fast-acting property,control efficiency and persistent effect,15% Fenbutatin · Pyridaben EC,45% Lime sulfur JG,73% Propargit EC and 1. 8% Abamectin EC had better effects,which were significantly better than other three acaricides.更多还原
