光肩星天牛生态控制模式的研究

The Study on the Model of Ecological Control of Long-horned Beetle

光肩星天牛（Ａｎｏｐｌｏｐｈｏｒａ ｇｌａｂｒｉｐｅｎｎｉｓ Ｍｏｔｓｃｈ）是钻蛀性害虫，国内２７个省有３７种树木被害甚至大批枯死，从而引起森林边向性发展，使有林地变为无林地，沦为沙漠或荒原。光肩星天牛是国际严格检疫对象。由于商品木质包装物携带光肩星天牛，近两年造成我国外贸损伤达２４０亿美元。所以，光肩星天牛的防治是一个亟待解决的问题。经过２０ａ的研究，取得了突破性进展，抑制住了森林的逆向性发展，使 １３３３ｈｍ２被害林变为高质量的林分，林木危害株率由９８．７％降为３．８％，产值增加７倍，生态效益、社会效益显著。

In this paper deals with the controlling of long horned beetles that bore the trees. Giant breakthrough has been made by the hard work of the authors in the past 20 years; thus, the trend of reverse development has been controlled. This result came out of the following: the sensitive tree species have been turned into the pest resistance and tolerance species; the trees made a guild and form the core of target tree species; the ecological control effect produced by the guild can prevent long beetle's spread and control its growth in population, so the damaged rate to trees can be reduced. As a result, the damaged woodland of 1333 hm2 has been changed into high quality forest, giving out remarkable social and ecological profit, in whieh the damaged rate was reduced from 98.7% to 3.8% and the output value was increased by 7 times. This achievement is now being popularized in the north, the northwest as well as northeast of China.
