| 摘 要： | 通过GC—MS分析，发现健康的与遭受华山松木蠹象Pissodes punctatus Langor et Zhang危害的华山松Pinusarmandii Franch树干以及华山松枝梢释放的挥发性单萜烯在含量上存在较大差别；利用Y-型双向选择嗅觉仪进行的室内趋向反应实验发现，处于补充营养期和交尾产卵期的华山松木蠹象对单萜烯表现出不同的趋向反应。在华山松枝梢挥发物中含量较高的（-）-β-蒎烯、月桂烯和柠檬烯引起补充营养期华山松木蠹象较大的趋向反应；在华山松树干韧皮部挥发物中含量较高的3-（＋）-蒈烯则引起交尾产卵期的华山松木蠹象较大的趋向反应。根据试验结果，对华山松和华山松木蠹象互作的机制进行了初步探讨。

| Abstract: | There was significant difference among monoterpene volatiles released from healthy, weevil damaged trunks of Pissodes punctatus and their branches, Walking P. punctatus in maturation feeding and sexually matured stages displayed different olfactory responses toward monoterpenes in a Y-tube olfactometer. Maturation feeding weevils displayed higher anemotaxis responses to (-) - β - pinene, myrene and limonene than those of sexually matured weevils; whereas (+) - carene, which was detected only in volatiles of trunk phloem, elicted more olfactory respones of sexually matured weevils than of maturation feeding weevils. Based on the test results, mechanism of Pissodes punctatus - Pinus armandii interaction was discussed. |
