摘　　要：[目的]研究大蓑蛾各发育期的形态特征及与其他种类蓑蛾的区别,并探讨其发生规律、生活习性和为害症状。[方法]观察大蓑蛾发育期形态特征并与其他种类蓑蛾进行比较;调查总结大蓑蛾与其他常见蓑蛾的发生规律;观察记录大蓑蛾的生活习性和为害特征。[结果]蓑蛾类成虫性二型,雌蛾无翅,触角、口器、足均退化,几乎一生都生活在护囊中;雄蛾具2对翅,飞行迅速;幼虫能吐丝营造护囊,并能负囊而行,探出头部蚕食叶片,蛹化于囊袋中。大蓑蛾在华北、华东、华中2年发生1代,广州发生2代,以老熟幼虫在蓑囊中越冬。大蓑蛾寄主广泛,主要为害梨、苹果、桃、葡萄、石榴等多种果树、林木花卉及农作物,主要以幼虫为害。[结论]该研究可为蓑蛾类昆虫的研究及防治提供依据。[Objective]The research aimed to study on the identification and occurrence of Clania variegata Snellen.[Method]The morphological features during maturity of C.variegate Snellen were observed and were compared with other common Clania insects.The regularities of outbreak of C.variegate Snellen and other common Clania insects were investigated.Then the living habit and damage symptoms of C.variegate Snellen were observed.[Result]The adults of Clania insects were sexually dimorphic.The female had no wing,and antenna,trophi and foot all degenerated,living in bags all life.The male had two pairs of wings,and flied quickly;larvae could make bags with silk,and could move with bags on back.They bit leaves when nosed head out of bags.And the pupation was in bags.C.variegate Snellen happened in North China,East China and Central China for one generation in two years,and two generations in Guangzhou,with ageing larvae in bags overwintering.C.variegate Snellen had extensive hosts,and it mainly was larvae who damaged.It damaged kinds of fruiter such as pear,apple,peach,grape,granada,and trees,flowers,corns.[Conclusion]This study could provide references for the research and control of Clania insects.
