以袋栽大杯蕈的害长头螨成虫为试虫,测定甲氨基阿维菌素苯甲酸盐(甲维盐)和螺螨酯对其室内毒力.结果表明:甲维盐的LC_(50)、LC_(95)分别为2.79 mg/L和15.50 mg/L,螺螨酯的LC_(50)、LC_(95)分别为10.41 mg/L和65.26 mg/L,说明甲维盐对害长头螨的活性好于螺螨酯.田间药效试验结果证明:在大杯蕈菌包覆土前和每次采摘后,用2.2%甲维盐微乳剂0.67～L 0 mL/L,喷水量1.0L/m~2,两潮菇后的防效可达到93.56%～96.05%,是目前防治害长头螨较理想的杀螨剂.
以袋栽大杯蕈的害長頭螨成蟲為試蟲,測定甲氨基阿維菌素苯甲痠鹽(甲維鹽)和螺螨酯對其室內毒力.結果錶明:甲維鹽的LC_(50)、LC_(95)分彆為2.79 mg/L和15.50 mg/L,螺螨酯的LC_(50)、LC_(95)分彆為10.41 mg/L和65.26 mg/L,說明甲維鹽對害長頭螨的活性好于螺螨酯.田間藥效試驗結果證明:在大杯蕈菌包覆土前和每次採摘後,用2.2%甲維鹽微乳劑0.67～L 0 mL/L,噴水量1.0L/m~2,兩潮菇後的防效可達到93.56%～96.05%,是目前防治害長頭螨較理想的殺螨劑.

The laboratory bioassay of emamectin benzoate and spirodiclofen against Dolichocybe perniciosa was conducted.The test results showed that the LC_(50) and LC_(95) of emamectin benzoate were 2.79 mg/L and 15.50 mg/L,respectively.LC_(50) and LC_(95) of spirodiclofen were 10.41 mg/L and 65.26 mg/L,respectively.The efficacy of emamectin benzoate against Dolichocybe perniciosa in the laboratory was better than that of spirodiclofen.Field control efficacy of emamectin benzoate(0.67 ml/L to 1.0 ml/L)against Dolichocybe perniciosa was 93.56%-96.05%.It is a good and safe acaricide for preventing and controlling Dolichocybe perniciosa.
