摘　　要：以黄瓜上的茶黄螨为试材,采用田间试验的方法,研究了5种杀螨剂对大棚黄瓜茶黄螨的防治效果。结果表明：1.8%阿维菌素乳油3 000倍液的防治效果最好,1-14d防效均达93%以上;2.5%甲氨基阿维菌素苯甲酸盐微乳剂5 000倍液,具有较理想的防治效果,1-14d防效达90.60%-99.27%;43%联苯肼酯悬浮剂3 000倍液,药后1d的防治效果不太理想,防效只有73.26%,可是随着施药时间的延长,防治效果逐渐提高,药后7d和14d的防治效果达95%以上;240g/L螺螨酯悬浮剂4 000倍液和110g/L乙螨唑悬浮剂5 000倍液的防治效果相对较差;综合考虑,在保护地防治蔬菜上的茶黄螨,推荐使用1.8%阿维菌素乳油3 000倍液、2.5%甲氨基阿维菌素苯甲酸盐微乳剂5 000倍液,建议在茶黄螨发生初期使用43%联苯肼酯悬浮剂3 000倍液。Taking Polyphagotarsonemus latus as material,the control efficiency of five acaracides against the Polyphagotarsonemus latus on cumcumber was studied by field test.The results showed that the 3 000 times dissolution of avermectin（1.8% EC）had the highest control efficiency against the P.latus,with a value of93%in 1-14 days after sprayed,followed by the 5 000 times dissolution of emamectin benzoate（2.5% ME）with a value of 90.60%-99.27%.The3 000 times dissolution of bifenazate（43%SC）showed low control efficiency of 73.26%in 1day after sprayed.However,the efficiency incereased with the time of sparying gradually,and the control efficiency reached above 95%in 7days and 14 days after sprayed.The 4 000 times dissolution of spirodiclofen（240g/L SC）of and 5 000 times dissolution of etoxazole（110g/L SC）showed lower control efficiency among the tested acaracides.In summary,3 000 times dissolution of avermectin（1.8%EC）and 5 000 times dissolution of benzoate（2.5% ME）were recommended for the regular usage in field.The 3 000 times dissolution of bifenazate（43%SC）was recommended in the early time occurance of P.latus.
