横坑切梢小蠹寄主云南松针叶及树皮的挥发性成分

Volatile Components in Needles and Bark of Pinus yunnanensis,the Host Plant of Tomicus minor

揭示横坑切梢小蠹对寄主云南松的选择机制,为筛选对横坑切梢小蠹具有生物活性的植物源引诱剂,实现对该虫的生态控制提供理论指导。采用萃取蒸馏结合气相色谱-质谱(GC-MS)联用技术,分析了云南松针叶和树皮中的挥发性成分。云南松针叶挥发性成分主要包括7类35种,分别是24种萜烯类、5种醇类、2种酮类、1种醚类、1种酚类、1种酯类和1种烷烃类;云南松树皮挥发性成分主要包括7类34种,分别是22种萜烯类、5种醇类、2种酮类、2种烷烃类、1种醚类、1种酚类和1种酯类。

The volatile components were determined in bark and needles of Pinus yunnanensis,the host plant of Tomicus minor to explore the selection mechanism of T. minor on host plants and provide references for screening effective attractants of the plant origin and ecological control of T. minor. Extractive distillation combined with gas chromatograph-mass spectrometry（ GC-MS） was selected to determine volatile components in needles and bark of P. yunnanensis. The needles contained 35 volatile components from 7 groups,including 24 terpenes,5 alcohols,2 ketones,1 ether,1 phenol,1 ester and 1 alkane.The bark contained 34 volatile components from 7 groups,including 22 terpenes,5 alcohols,2 ketones,1 ether,1 phenol,1 ester and 2 alkanes.
