摘　　要：该文以马尾松、油松、华北落叶松 3种我国主要针叶树为对象 ,分析比较了 3种松树在受松毛虫危害后 ,所产生的迅速诱导抗性和滞后诱导抗性 ;研究了取食相应的受害针叶后 ,其生长发育情况的变化 ;探讨了松树诱导抗性对松毛虫种群动态的作用过程 ,总结了我国主要松树诱导抗性的一般规律 ,为分析松毛虫发生机理及松毛虫综合管理提供理论依据 .The rapid and lag induced resistance of three types of China pines, Pinus massoniana Lamb., P. tabulaeformis Carr. and Larix principis rupprechzii Mayr, after injured by insects were compared and analyzed. The results showed that the contents of secondary metabolites of pine were decreased and the content of volatile substance of pine was increased after being damaged by pine caterpillars. The lag changes of chemical substance were observed in needles of these three main pines after damaged by pine caterpillars. Higher mortality and lower faculty were found in pine caterpillars fed on the damaged pine needles. Furthermore, the theoretical basis for the integrated management of China pine pests was discussed in this paper.
