在实验室条件下，以取食痕／ｃｍ２ 、着卵数／ｃｍ２ 等指标，采用自由选择法与非自由选择法测定了美洲斑潜蝇（Ｌｉｒｉｏｍｙｚａ ｓａｔｉｖａｅ Ｂｌａｎｃｈａｒｄ） 对菜豆属、豇豆属、甜瓜属、丝瓜属、苦瓜属、葫芦属中１６ 个蔬菜品种（ 系） 的选择性差异。结果表明美洲斑潜蝇对黄瓜津杂４ 号、菜豆特长架豆、豇豆之豇２８ － ２ 品种的取食、产卵选择性较差，表现为非嗜好；而对黄瓜津春４ 号、菜豆玉豆３５ 、豇豆无架豆的取食产卵选择性较强，表现为嗜好性；对不同属植物的选择性从强到弱依次为菜豆属＞ 豇豆属＞ 甜瓜属＞ 丝瓜属＞ 葫芦属；对苦瓜属表现为不选择 Under laboratory conditions, the indica (Liriomyza sativae Blanchard) was used to determine the content of bean, genus Vigna, melon , Gourd genus, bitter melon genus, Cucurbita 16 varieties of vegetables (lines) selective differences. The results showed that the feeding preference and the spawning selectivity of Cucurbit peacock flies on Cuzaizuza No.4, Begonia longicolata and Cowpea asparagus 28 - 2 were poor, which showed non - hobby preference. On the other hand, Cucumber Jinchun 4, Jade beans 35, cowpea no shelf beans strong preference for feeding on the spawning, showing the hobby; for different genus selectivity from strong to weak, followed by the order Beans> Cowpea> Melon> Loofah> Cucurbita The performance of the bitter gourd is not selected
