摘　　要：【目的】筛选山楂叶螨Amphitetranychus viennensis Zacher对螺螨酯的抗药性,并明确其对7种杀螨剂的交互抗性。【方法】采用室内生物测定的方法,研究山楂叶螨对螺螨酯的抗性发展趋势及其交互抗性。【结果】用螺螨酯筛选山楂叶螨21代,抗性上升11.65倍;抗性品系对乙螨唑存在明显的交互抗性,抗性倍数为6.30;对噻螨酮存在负交互抗性,抗性倍数为0.69;对阿维菌素、炔螨特和三唑锡不存在交互抗性,抗性倍数分别为1.15、1.25、1.78;对哒螨灵和联苯肼酯有产生交互抗性的可能,抗性倍数分别为3.46和2.79。【结论】螺螨酯防治山楂叶螨存在抗性风险,抗螺螨酯的山楂叶螨品系会产生交互抗性,上述结果可为果园科学使用螺螨酯和合理轮换用药提供理论依据。[Objectives] To assess the develop ment of resistance, and cro ss-resistance, i n Amphitetranychus viennensis Zacher to seven acaricides. [Methods] Resistance was evaluated using biological assays conducted in a laboratory. [Results] After selection for spirodiclofen resistance over 21 generations, the resistant strain had 11.65-fold resistance to that acaricide, 6.30-fold low level cross-resistance to etoxazole and 0.69-fold negative resistance to hexythiazox. Cross-resistance to abamectin, propargite and azocyclotin was 1.15, 1.25 and 1.78-fold, respectively, whereas resistance to pyridaben and bifenazate was 3.46 and 2.79-fold, respectively. [Conclusion] A. viennensis has the capacity to develop resistance to spirodiclofen, and cross-resistance to some other acaricides. These results provide a theoretical basis for the rational rotation of pesticides in apple orchards.
