山地木蠹蛾属鳞翅目木蠹蛾科,以幼虫危害紫胶寄主树,如秧青、牛肋巴、泡火绳等,特别是秧青、牛肋巴的重要蛀干害虫。该虫在云南各产胶区均有不同程度的危害。自1972年开始,我们在景东地区对此虫的生物学特性和防治方法断断续续进行了一些研究,现将初步结果整理如下: 一、危害情况幼虫孵化后,初喜群居,3龄以前在树干表皮钻蛀较浅的洞,排出少量的虫粪;3龄后,幼虫向木质部纵深危害,钻成不规则的隧道,排出较多的虫粪,破坏树木的生理机能,影响养分和水分的输导,使树势逐年衰弱,其它害虫则相继危害,如天牛、白蚁、小蠹虫,以致整株枯死。二、形态特征 Hill moth is a genus of Lepidoptera, in which the larvae are responsible for the host tree of lac, such as young seedling, beef nibbling, fire ropes and so on, especially the important pest insects of young seedling and beef nibbling. The insects in the rubber producing areas in Yunnan have varying degrees of harm. Since 1972, we conducted a number of studies on the biological characteristics and control methods of this pest in the area of ​​Jingdong. The preliminary results are summarized as follows: I. Hazards After the larvae hatch, After 3 years of age, the larvae endangered to the xylem, drilled irregular tunnels, excreted more insect manure, destroyed the physiological function of trees, affecting the transport of nutrients and water Guide, so that the potential decline of the tree, the other pests have been endangered, such as beetles, termites, beetles, so that the whole plant died. Second, the morphological characteristics
