摘要:
榆毒蛾是榆树的食叶害虫之一，在吴起县发生严重。通过室内饲养观察和田间调查，研究了该虫的生活史、生活习性和发生规律。结果表明该虫在吴旗县一年发生2代，以幼虫在粗皮下或树基越冬，幼虫6～8龄，具吐丝下垂习性，在阴坡立木被害重于阳坡，成虫夜间活动，有趋光性。卵成串状产于叶片背面或嫩枝上。该虫在倒春寒发生晚、次数多的年份发生轻，公路旁的榆树受害相对较轻。被害严重的榆树春梢和秋梢生长量明显低于健康植株。可采用灯光诱杀或在卵孵化盛期和幼虫为害初期喷菊酯类农药防治。西北林学院学报22卷第6期 莫延德等吴旗县榆毒蛾研究
Abstract:
Ivela ochropoda is one of the main defoliator pest occurred in Ulmus pumila ,and is very serious in Wuqi County. The pest lifecycle,habits and characteristics,occurrence ragurity were studied. The results showed that there were two generations in one year,and there were 6-8 instars in duration of larvae's development. Larvae overwinters under bark or in base of tree. Adult were phototaxis and active on night. The eggs were oviposited at the back of leaves or tender breach in order. Damage of this pest to elm tree was more serious at north of hill than at south of hill,and than in side of highway. Growth quality of new tip after damaged is lower than healthy tree. Tap and kill this pest with mothkilling lamp and with pesticide was suggested to control it.
