1991年6月初我们在漳州地区进行疫情调查时发现在5月初南靖县南坑乡4000多亩红栲林遭到舞毒蛾Lymantria dispar(Linnaeus),严重为害,据调查表明,栲树被害株率100％,虫口密度135头/m~3,被害严重的树木,每棵害虫达数千头。仅3～4天时间,成片成片的树叶被吃光,使人见了触目惊心。舞毒蛾在当地不仅为害红栲,也为害附近的杨梅,但不为害毛竹。 In early June 1991, when we conducted an epidemic investigation in Zhangzhou, we found that more than 4,000 mu of red mulberry trees in Nankeng Township, Nanjing County in early May, were seriously damaged by Lymantria dispar (Linnaeus). According to the survey, 100%, population density 135 head / m ~ 3, severely damaged trees, each pest up to thousands of heads. Only 3 to 4 days, into a piece of leaves were eaten, people see the startling. Gypsy moths are not only harmful to the local red mulberry, but also damage the nearby bayberry, but not harmful to bamboo.
