大蓑蛾的鉴别及发生规律研究

[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。
