摘  要：
【目的】筛选出对斜纹夜蛾具有增效作用的甲氨基阿维菌素与杀虫双最佳配比,为其混剂研发及现场桶混应用提供科学依据。【方法】采用浸叶法测定甲氨基阿维菌素、杀虫双单剂及其混剂对斜纹夜蛾3龄幼虫的毒力,筛选出具有增效作用的最佳配比。【结果】甲氨基阿维菌素:杀虫双为70:30和60:40即有效成分质量比为0.14:243.00和0.12:324.00时毒效比分别为1.34和1.45,表现出增效作用,其共毒系数分别为125.93和151.08。【结论】甲氨基阿维菌素与杀虫双按有效成分质量比为0.12:324.00混配时,对斜纹夜蛾幼虫的毒力增效作用最明显,为防治斜纹夜蛾的最佳配比。

摘  要：
[Objective]Optimum ratios of emamectin benzoate and bisultap were screened for controlling Spodoptera litura in order to find out the optimum ratio with synergetic action.[Method]The toxic effects of emamectin benzoate,bisultap and their mixtures against 3-year-old larva of Spodoptera litura were measured using leaf dipping method.[Result]When the ratio of emamectin benzoate and bisultap was 70:30 and 60:40 with the effective component ratio of 0.14:243.00 and 0.12:324.00,the toxicity ratios were 1.34 and 1.45 and the co-toxicity coefficients were recorded as 125.93 and 151.08,respectively,which indicated that the mixtures played a synergetic role.[Conclusion]Emamectin benzoate and bisultap mixture had the best synergistic effect when their effective component ratio was 0.12:324.00.
