摘　　要：本文比较了7种杀螨剂常规用量对柑橘红蜘蛛的田间药效,结果表明:速效性和持效性均较好的药剂为三唑锡25%可湿性粉剂和阿维菌素1.8%乳油;而丁醚脲25%乳油、苯丁锡50%可湿性粉剂和螺螨酯240克/升悬浮剂的速效性较差,但持效性较强,尤其是苯丁锡50%可湿性粉剂。此外,哒螨灵15%乳油的速效性在几种药剂中仅稍差于三唑锡25%可湿性粉剂,但持效性却是几种药剂中最差的;而炔螨特57%乳油相对其它药剂而言,速效性和持效性均表现一般,持效性也仅显著好于哒螨灵15%乳油。The control efficiency of the recommended concentration of seven acaricides on Panonychus citri were detected in citrus orchard. The result of field efficacy trials showed that Azocyclotin 25% WP and Avermectins 1.8% EC showed the better quick-acting and lasting ef- fect. And Diafenthiuron 25%EC, Fenbutatin-Oxide 50% WP and 240g/L SC showed the better the lasting effect, but the quick-acting effect of them were poor, especially Fenbutatin-Oxide 50% WP. In addition, the quick-acting effect of Pyridaben 15% EC was better, only was worse than Azocyclotin 25% WP, but the lasting effect was worst in all tested acaricides. The quick-acting and lasting effect of Propargite 57% EC was ordinary in all tested acaricides, except the lasting effect of it was only significantly better than Pyridaben 15% EC.
