In this work, we describe the insecticidal activity against of flavanone derivatives (naringin, naringenin and hesperidin) complexed to copper (II). For the assays, the compounds were incorporated into an artificial diet and offered to during its larval period. The duration of larval and pupal phases, the weight of pupae and the percentage of dead insects at the end of the larval phase were evaluated. Among the tested compounds, the free flavanones and and the complexes and showed a shortening of the larval phase when compared to the control. Complex showed the highest toxicity, with 96.66% larval mortality. This is the first report on the insecticidal activity of the Cu complexes of the flavanones naringin, naringenin and hesperidin.[Formula: see text].
在这项工作中，我们描述了黄酮类衍生物（柚皮苷、柚皮素和橙皮苷）与铜（II）形成配合物的杀虫活性。对于这些测定，将化合物掺入人工饲料中，并在幼虫期提供给昆虫。评估了幼虫和蛹期的持续时间、蛹的重量以及幼虫期结束时死亡昆虫的百分比。在所测试的化合物中，游离黄酮类化合物 和 以及配合物 和 与对照相比，幼虫期缩短。配合物 表现出最高的毒性，幼虫死亡率为 96.66%。这是首次报道柚皮苷、柚皮素和橙皮苷的黄酮类 Cu 配合物具有杀虫活性。[化学式：见正文]。
