摘　　要：重阳木是世界上具有重要价值的树种之一,近年来重阳木帆锦斑蛾BischofiapoiycarpaCramer对其危害日益突出。该害虫在我国许多省区都有不同程度的发生,2006年在安徽省合肥地区暴发成灾。经过室外调查和室内饲养观察,分析了其暴发成灾的原因,明确了该虫的形态特征、年生活史和生活习性。该虫在合肥地区1年发生4代,有世代重叠现象。主要以幼虫在重阳木枝干的树皮、裂缝等处越冬。越冬幼虫至次年4月开始活动。在7月和8月份,以第2代和第3代幼虫危害最重。建议采用植物检疫、人工捕杀、微生物农药及化学杀虫剂等多种方法加以防治,自然天敌对其也有一定的控制作用。Bischofta polycarpa is one of the important valuable cosmopolitan trees. Recently, Histia rhodope Cramer has caused serious damage to B. poiycarpa. It has occurred at different extent among many provinces of China and this year the pest outbreaks on B. poiycarpa in Hefei, Anhui Province. The causes of the outbreak were analyzed. Its biological characteristics were studied by field researching and indoor breeding, its main morphological characteristics, life history and living habits ware made out. H. rhodope occurs 4 generations a year in Hefei area with overlapped generations. It overwinters mainly in the stage of larvae in the thick barks or cracks of trees. It resumes activity in April of the next year. The larvae of the second and third generations can cause serious damage to B. poiycarpa from July to August. There are various control methods suggested to control this pest, including plant quarantine, manpower, microorganism pesticide, chemical pesticide, and natural enemies have certain effort to control it too.
