(Spodoptera frugiperda) moths were evaluated. Only substitutions on the 1,3,4-oxadiazole moiety dictated bioreactivity, with 8q2 m-CF3Ph being the most effective against Plutella xylostella, showing 80%–93% mortality at a concentration of 0.5–500 μg ml−1 while the others remained inactive or less active (highest mortality being 63%). The larvicidal activity against Spodoptera frugiperda was inferior
评估了含有吡啶基吡唑-4-甲酰胺的 1,3,4-恶二唑环对小菜蛾 ( Plutella xylostella ) 和夜蛾 ( Spodoptera frugiperda ) 蛾的杀虫活性。只有 1,3,4-恶二唑部分的取代决定了生物反应性,其中8q2 m -CF 3 Ph 对小菜蛾最有效,在 0.5-500 μg ml −1的浓度下显示 80%–93% 的死亡率,而其他人则保持不活跃或不太活跃(最高死亡率为 63%)。对草地贪夜蛾的杀幼虫活性低于小菜蛾,最高死亡率为33%。8q5晶体获得并分析,揭示了分子内氢键和分子间 π π 相互作用的影响。
