柳毒蛾为害杨柳树木,我省泰安、临沂、烟台等地区为害较重。如1972—1973年在太安良庄公社茅茨大队的防护林内大发生,加拿大杨、箭杆杨等杨树叶片几乎全被食光,虽时值盛夏,林带却似深秋景色,严重影响林木生长,降低了防护林的效能。在其他地区,此种情况也屡见不鲜。 柳毒蛾属鳞翅目毒蛾科。成虫全体白色,稍有光泽,足的胫节和趺节有黑白相间的环纹,触角主干也有黑褐色与白色相间的斑纹(杨毒蛾和其相似,但触角主干白色,易于区别)。卵灰白色,园形,排列成堆,堆上覆有泡沫状粘液。幼虫黑褐色,头部淡褐色,体背有灰白色较狭的纵带,中央有暗色的背中线,体侧各有黑褐色纵带一条,其上毛瘤亦为黑褐色,着生黄白色长毛(杨毒蛾头黑色,背中线较宽,黄白色,体侧毛瘤红色)。蛹黑褐色,披有褐色毛,尾部有棕色毛簇一丛,(杨毒蛾蛹为黑色,有白斑)。
