星天牛是木麻黄、行道树、柑桔、枇杷等多种林木和果树的一种蛀干性害虫,在我县分布较广,危害严重,影响着林业和水果生产。过去对星天牛防治采用打孔钩杀和塞药灭虫等方法。前者损伤树体,且影响正常生长,造成树体伤痕愈合困难,易被风折。后者化工大,费力气,还污染环境。为寻求较理想防治星天牛的新途径,笔者于1985年起开展了天牛肿腿蜂(Sclerodrema sp.)的引种繁殖及其田间应用试验,初步结果报导如下。 一、天牛肿腿蜂的引种繁殖 (一)种蜂来源 种蜂于1985年3月从上海市园林技校引入。 (二)采集寄主 于每年底采集本县行
Aspen australis is Casuarina, road trees, citrus, loquat and other trees and fruit trees a borer pests, distributed in my county wider, serious harm to forestry and fruit production. In the past, the prevention and control of Aspleniumus were used to kill and plug insecticide and other methods. The former damage the tree, and affect the normal growth, resulting in tree wound healing difficult, easy to wind break. The latter chemical large, laborious, but also pollute the environment. In order to find a new way to control Asteraceae, the author started the experiment of introduction and propagation of Sclerodrema sp. In 1985, and the preliminary results are reported as follows. First, beetle beetle breeding introduction (a) kind of bee source bee was introduced in March 1985 from the Shanghai Landscape School. (B) acquisition host at the end of each year to collect the county line
