摘　　要：二斑叶螨(Tetrangchus urticae)和朱砂叶螨(Tetranychus cinnabarinus)是危害食用玫瑰的2种重要害螨,但是目前缺少关于食用玫瑰叶螨防治的农药产品登记。为筛选防治二斑叶螨和朱砂叶螨2种害螨的高效安全药剂,分别采用浸叶法和玻片浸渍法测定7种药剂对2种叶螨卵和雌成螨的致毒作用,并开展田间试验评价4种药剂对食用玫瑰的安全性和对2种叶螨的防治效果。室内毒力试验表明,腈吡螨酯、阿维菌素和联苯肼酯对2种害螨均具有较好的毒性,对二斑叶螨成螨和朱砂叶螨成螨的LC_(50)分别为9.068~26.590、2.390~6.107 mg/L,对二斑叶螨卵和朱砂叶螨卵的LC_(50)分别为1.705~16.798、0.846~7.948 mg/L;螺螨酯则对2种叶螨卵具有极好的致毒作用,对二斑叶螨卵和朱砂叶螨卵的LC_(50)分别为2.622、1.674 mg/L。田间试验结果表明,腈吡螨酯、阿维菌素、螺螨酯和哒螨灵等4种药剂对3个品种的食用玫瑰生产安全、无药害,腈吡螨酯、阿维菌素和螺螨酯对食用玫瑰2种叶螨防治效果优于常用药剂哒螨灵,可作为替代哒螨灵的药剂轮换使用。Tetrangchus urticae and Tetranychus cinnabarinus are two important mites that harm edible rose.Up to now,there is a lack of registered insecticides for controlling edible rose mites.To screen both efficient and secure pesticides for controlling edible rose mites,in this study,leaf-dip method and slide-dip method were used to test the toxicity of 7 insecticides against eggs and femal adults of T.urticae and T.cinnabarinus,respectively.Field experiments were also conducted to evaluate the safety of edible rose and control efficacy against the two kinds of mites of 4 insecticides.The toxicity results demonstrated that the toxicity of cyenopyrafen,abamectin,and bifenazate possessed excellent toxicity against the two kinds of mites,and the LC_(50) value were 9.068~26.590 mg/L for T.urticae adults and 2.390~6.107 mg/L for T.cinnabarinus adults,and the LC_(50)value for eggs were 1.705~16.798 mg/L and 0.846~7.948 mg/L,respectively.Spirocliclofen possessed excellent toxic effects on eggs of the two kinds of mites,with the LC_(50) values of 2.622 mg/L for T.urticae eggs and 1.674 mg/L for T.cinnabarinus eggs.The results of the field experiments showed that the four insecticides including cyenopyrafen,abamectin,spirocliclofen,and pyridaben were safe for three edible rose varieties,and the control efficacy of the insecticides including cyenopyrafen,abamectin,and spirocliclofen against the two kinds of edible rose mites were better than that of pyridaben,and they could be applied as the insecticides replacing pyridaben.
