| 摘 要： | 白缘苇野螟是一种为害芦苇顶叶的害虫。湖北地区一年发生三代,以第三代老熟的幼虫在芦苇茎秆内结薄茧越冬;成虫有趋光性;幼虫共分七龄,四龄前食量小,四龄后食量剧增,每龄可在苞内食尽一片心叶。该虫的发生和为害程度与气候、苇田环境、收割质量、汛期水位、天敌等因子有密切的关系,据此,最佳防治方法是冬前砍割干净,翌年3月前将芦苇处理完毕或药剂封堆,以防羽化的成虫返回苇田。

| Abstract: | Common reed caseworm, sclerocona acutella (Eveersmann) is a kind leaf-eating insect-pest. It damages the leaves at the top of the phragmites communis so thatthe rolled pockets are formed in the leaves. There are three generations per year inHabei province with the old larvae of the third generation overwintering in the stalk ofphragmites communis. The adults have phototaxis. The larvae have seven instans. Theyhave less feeding quantity before the fourth instar. After that, they can eat up a wholeheart-leaf in an iastar. The important factors of the pest-outbreak are the quality ofreaping, the climate, the environment of field, the water level of the Yangtze Riverin summer and their natural enemies. As the most important factor is the quality ofreaping, therefore, elaborate reaping is the best measure to control this insect-pest. |
