构树Broussonetia papyrifera Vent.是一种经济价值较高的树种,但在其育苗及生长过程中,经常受到构月天蛾Parum colligata(Walker)的为害,发生严重年份常将叶柄及嫩茎啃食残缺,致使树势受到严重影响,甚至不能再萌芽而枯死。为提供防治构月天蛾的有利时机,现将其形态及生活习性整理出来,供参考。 Broussonetia papyrifera Vent. Is a tree species with higher economic value. However, it is often damaged by Parum colligata (Walker) in its breeding and growth. In severe years, petiole and tender stem are often eaten Incomplete, resulting in serious damage to the tree potential, and even can not even germinate and die. In order to provide a favorable opportunity to control the crape mytilus, the morphology and living habits are now sorted out for reference.
