In Martinique, is a common pest of tomato and is responsible for significant economic losses. To fight against proliferation and damage, corn could be used as a trap crop since larvae growth in the corn silk was inhibited by the presence of some flavonoids. However, only some corn varieties show an efficient inhibitory activity against depending on their flavonoid composition. In order to be able to select corn varieties with inhibition potential to be tested as a trap plant, a metabolomic approach was developed to compare the flavonoid composition of corn silks from resistant and nonresistant varieties. Quantitative analysis using UHPLC/TQ MRM MS associated with statistical treatments allowed the determination of the most concentrated and discriminant flavonoids of the resistant Java variety that clearly stood out, presenting a higher content in several -glycosyl--glycosyl luteolin and apigenin derivatives such as maysin molecules.
在马提尼克岛， 是番茄的常见害虫，会造成重大的经济损失。为了对抗 的繁殖和破坏，可以使用玉米作为诱集作物，因为玉米花丝中的 幼虫的生长受到一些类黄酮的抑制。然而，只有一些玉米品种对 表现出有效的抑制活性，这取决于它们的类黄酮组成。为了能够选择具有抑制潜力的玉米品种作为诱捕植物进行测试，开发了一种代谢组学方法来比较抗性和非抗性品种玉米花丝的类黄酮组成。使用 UHPLC/TQ MRM MS 进行定量分析并结合统计处理，确定了抗性 Java 品种中最集中和最具区分性的类黄酮，该品种明显突出，在几种 -糖苷基--糖苷基木犀草素和芹菜素衍生物（如 maysin 分子）的含量更高。
