摘　　要：小蠹虫是针叶树木的重要害虫。为减轻或避免小蠹虫的危害,针叶树木在长期的进化过程中,逐步发展形成了由原生性防御和诱导性防御构成的特定抗御体系,最终在与小蠹虫的竞争中获得了一席之地。文章综合了国内外在该领域的最新研究成果,对针叶树木防御体系的基本特征、产生机制及其生态学功能进行了系统阐述。Bark beetles are main pests in coniferous trees. In order to resist or reduce the damage caused by bark beetles, coniferous trees have on their long way of evolution developed a set of combined resisting systems： preformed and induced defense system. The trees finally overtake the beetles. The article integrates the latest achievements in the field throughout the world and systematically summarizes the substantial attributes, developing mechanisms as well as ecological functions of conifers＇ defense systems.
