摘　　要：柑橘全爪螨是一种世界性害螨,目前对许多药剂已经产生抗性。药剂复配是治理抗性问题,延长药剂使用寿命的重要手段。为筛选出增效明显的复配新产品,本文选取联苯肼酯作为标准药剂,与阿维菌素和氟啶胺分别进行复配,并采用叶碟喷雾法测定其联合毒力及增效作用。结果表明,联苯肼酯、阿维菌素和氟啶胺的单剂LC 50分别为16.43、0.29 mg/L和12.63 mg/L。联苯肼酯与阿维菌素复配比例为19∶1和15∶5的共毒系数分别为135.02和158.40,具有增效作用。联苯肼酯与氟啶胺在6∶4、7∶3、5∶5、9∶1、8∶2复配比例的共毒系数分别为466.28、410.61、370.22、311.15和275.85,增效作用显著。Panonychus citri is a worldwide pest mite known for its resistance to various acaricides.Combining acaricides is an effective strategy to solve the resistance problem and extend the shelf life of acaricides.In this study,compound formulations comprising bifenazate,with abamectin,or fluazinam were screened to identify new compound products with clear synergistic effects.The co-toxicity and synergistic effect of these compound acaricides were determined using the leaf-spray method.The LC 50 values were determined as 16.43 mg/L for bifenazate,0.29 mg/L for abamectin,and 12.63 mg/L for fluazinam.Co-toxicity coefficients of 135.02 and 158.40 were observed for bifenazate and abamectin at ratios of 19∶1 and 15∶5,respectively,indicating a synergistic effect.For bifenazate and fluazinam at ratios of 6∶4,7∶3,5∶5,9∶1,and 8∶2,co-toxicity coefficients of 466.28,410.61,370.22,311.15,and 275.85,were recorded,displaying significant synergistic effects.
