摘　　要：测定了5种不同作用机理杀螨剂对苹果树红蜘蛛的防效,并对其田间的应用效果进行评价。结果表明:三唑锡20%悬浮剂800倍液和唑螨酯5%悬浮剂2 000倍液速效性和持效性均较好,药后2d防效即达到90%以上,持效期25d以上;矿物油99%乳油和阿维菌素1.8%乳油速效性一般,但持效期较长,也能达到25d以上,哒螨灵40%可湿性粉剂防效一般。三唑锡20%悬浮剂和唑螨酯5%悬浮剂可快速有效地防治苹果树红蜘蛛,对天敌等影响较小,对作物安全,可作为防治的首选药剂使用。In this paper, five pesticides with different mechanisms were conducted against Panonychus ulmi through field trail. The results showed that 20% azocyclotin SC and 5% fenpy- roximate SC had significant effect on P. ulmi with the control efficacy over 90% at second day and 25th day after the treaments. 99% petroleum oil EC and 1.8% abamectin EC also had good effects on P. ulmi, these two pesticides had an effective period of more than 25 days in the fields. 20% azocyclotin SC and 5% fenpyroximate SC could control P. ulmi timely and effectively and were safe on natural enemies and crops. Therefore, they were worth to select priority in the field use.
