研究表明，美洲斑潜蝇的寄主植物主要有茄科、豆科、葫芦科，其次有十字花科、菊科、锦葵科等。受害严重的作物，平均单叶有虫道１００．４个，单叶有幼虫４６．３头，被害叶率达８５．２％，有虫株率和被害株率均达１００％；研究还表明，美洲斑潜蝇从植株下部开始为害，且以植株中上部虫量最多，而被害叶位多逐叶上移；通过室内饲养和田间观察获知美洲斑潜蝇在茄子、西葫芦和地芸豆上各虫态的发育历期，并描述了其习性
Studies have shown that the main host plants of the American Leafminer lizards Solanaceae, Leguminosae, Cucurbitaceae, followed by Cruciferae, Asteraceae, Malvaceae and so on. The severely affected crops had an average of 100.4 insect larvae per single leaf, 46.3 single leaf larvae, a rate of 85.2% for the infected leaves, and a rate of 100% for both the worm strains and the victim plants. The study also showed that , The American leafminers began to damage from the lower part of the plant, and the upper part of the plants had the most amount of insect and the leaves of the victim were more leaf-by-leaf shifted upwards. It was learned from the indoor feeding and the field observation that the American leafminers were found on eggplant, zucchini and kidney bean respectively The developmental state of the worm state, and describes its habits
