摘　　要：杞柳瘿蚊Rhabdophaga salicis Schrank是沿淮地区危害杞柳的重要害虫。该虫在沿淮地区1a发生5代，以幼虫在当年生被害杞柳柳条上的虫瘿内越冬。翌年3月上旬开始化蛹，除越冬代外各代幼虫发生盛期分别为4月上旬、5月上旬、6月中旬和8月上旬，有明显的世代重叠现象，越冬代幼虫于10月中下旬陆续进入越冬状态。幼虫共3龄。蛹期10～12d。蛹的发育过程根据形态变化可分为4个阶段。Rhabdophaga salicis Schrank is an important pest attacking osier along Huaihe River. It has 5 generations a year in low-lying area along Huaihe River and overwinters as matured larva in the galls in the infested wickers. It pupates in the first ten days of March the next year. The hatching peaks of the larvae of different generations except the overwintering generation are first ten days of April and May, mid June and first ten days of August. The generations overlap. The larva of the fifth generation overwinters from late October. The larva has 3 instars and the pupal stage is 10-12 days which can be divided into four phases according to its morphological changes.
