本文研究了粗鞘双条杉天牛幼虫体外寄生蜂双连斑头陡盾茧蜂的形态学、生物学、生态学、国内外分布。繁殖利用方法、寄主范围及对粗鞘双条杉天牛大面积的防治,该蜂寄生于粗鞘双条杉天牛上为其寄主的首次记录。人工释放后林间当代寄生率为70—80％左右,多年放蜂防治效果达90％左右。它具有寻找寄主能力强、扩散迅速、控制范围广等优点。比用化学农药呋喃丹省工、简便,效果比用呋喃丹约高出一倍,且费用只及1/8。
In this paper, the morphology, biology, ecology and distribution both in vitro and in vivo of the parasitoid Dipterocarpaceae larvae were studied. Propagation and utilization methods, the host range and the large-area control of the crude Cunninghamia lanceolata, the bee parasites on the first two pairs of caterpillars for its host host. After artificial release, the modern inter-forest parasitic rate is about 70-80%, and the prevention and control effect of beekeeping for many years reaches about 90%. It has the ability to find the host strong, rapid proliferation, control a wide range of advantages. Carbofuran than the chemical pesticides workers, simple, the effect than using carbofuran about doubled, and the cost is only 1/8.
