摘要
美洲斑潜蝇在温州地区室内饲养１年发生１３～１４代。一般菜区以蛹越冬，冬季大棚栽培的番茄、茄子和暖冬年份蚕豆大田能以幼虫和蛹同时越冬。１１月中旬露地越冬蛹开始进入滞育状态，滞育期长达１１０天左右，越冬主要寄主是蚕豆，尚有少量白菜、莴苣及茄果、瓜类的幼苗。自然条件下，世代重叠明显。初步明确该虫的发育起点温度为７．５３℃（卵、幼虫、蛹的平均值）。
The indoor raising test showed that Liriomyza sativae (blanchard) had 13 to 14 generations in a year in Wenzhou.Liriomyza sativae overwintered in pupa in Wenzhou field, in broad bean that planted in warm winter or in tomato and eggplant planted in the shelter,both larva and pupa could survive .In midNovember,the pupa started to diapuse and kept for about 110 days at the most.Broad bean,little Chinese cabbage,lettuce,eggplant's and melon's seeding were the main host for Liriomyza sativae during winter.Various generations of the pest overlapped obviously in the field ,The temperature of starting point for L.sativae growth is 7.53℃.
