三线雪舟蛾1991年在邛崃山系地区暴发成灾,严重危害桤木、马桑、桦木、麻柳等树种。成都市的邛崃、大邑、崇庆,都江堰、彭县、温江、新津等县、市凡有桤木树分布的林地均有此虫发生。三线雪舟蛾危害时,以幼虫取食叶片,叶片吃光后亦啃食嫩枝,影响桤木树生长,甚至整株枯死。三线雪舟蛾的幼虫刺毛有毒,触到人体皮肤引起红肿呈斑块状,并产生剧烈痒痛。 为了摸清其生物学特性,找出防治方法,我县森林病虫防治检疫站1991年3月23日从野外采回幼虫500条,分5笼每笼100条进行人工饲养,同时在野外设点观察。现将饲养观察结果小结如下:
Three-lane snow moth 1991 outbreaks in the Qionglai Mountains, seriously endangered alder, marsan, birch, mahogany and other tree species. Chengdu, Xuyi, Dayi, Chongqing, Dujiangyan, Peng County, Wenjiang, Xinjin and other counties, where the distribution of alder wood trees have this worm occurred. Third-line snow moth damage, the larvae feeding leaves, the leaves eaten after eating grazing, affecting alder growth, and even the whole plant died. Third-line lark moth larval bristles poisonous, touching the human skin caused by swelling was plaque, and severe itching. In order to find out its biological characteristics, to find out the prevention and treatment methods, my county forest pest control quarantine station on March 23, 1991 500 larvae were collected from the field, divided into 5 cages per cage 100 for artificial feeding, while in the wild Watch. Breeding observations now summarized as follows:
