摘　　要： 美洲斑潜蝇在寄主作物上的虫道呈蛇形,且主要分布在叶片正面,明显有别于豌豆彩潜蝇、番茄斑潜蝇。幼虫在不同寄主作物上蛀食能力差异明显,在丝瓜、茄子和豇豆上单个潜道面积分别为53.34、51.76、34.55 m m 2 。不同龄期幼虫蛀食量差异较大,其中以3 龄幼虫为最大,约占蛀食量59.30% ～70.68% 。在25℃下,卵历期2.3～2.8 d, 寄主作物对卵的发育影响不明显,对幼虫历期有一定的影响。 The miner damaged by Liriomyza sativae was a serpentine tunnel, which was different from Chramatomyia harticola and L. bryoniae . The feeding capacity of the larvae was variable among the crops, as well as among the instars. Of three instars, the third instar was the biggest in boring area by the range from 59.30% to 70.68%. The duration of larvae was influenced by hosts, while no effect on the duration of eggs, which was 2.3～2.8 days at 25℃.
