摘要
分月扇舟蛾Ｃｌｏｓｔｅｒａａｎａｓｔｏｍｏｓｉｓ（Ｌｉｎｎａｅｕｓ）为杨、柳等的重要食叶害虫之一，分布广，为害严重。在南充市年发生６代，以３龄幼虫越冬，世代重叠。１～５代幼虫为５个龄期，越冬幼虫则有６个龄期。每雌平均产卵６１４．２８粒。优势天敌多，对核虫有显著控制效果。采用人工防除和根部施呋喃丹，保护利用天敌，是控制该虫的关键措施。
Clostera anastomosis(Linnaeus),a leaf-eating insect attacking poplar and willow trees,wasfound to have six overlapping generations in the ecological environment of Nanchong,Sichuan。Ithibernated in the form of the 3-instar larvae. Larvae of the first five generations had five instarstages while the sixth generation larvae had six instar stages,The egg number laid by a femaleranged from 28 1.1 to 7 59.5, averaging 614.28.Its numerous predominant natural enemiesprovided an effective control.Manual control,Puradan appllcation by the root,protection of thenatural enemies constitute the key management measures for the pest.
