摘要:

分布于山西的油松树脂中的挥发性物质主要成份为?-(+)-α蒎烯、(S)-(-)-β-(+)-3-蒈烯,占萜烯总量的97%以上,其中(S)-(+)-3-蒈烯的比例最大,另外还有得叶烯、(+)-柠檬烯、莰烯、阵二烯和水芹烯等成份。触角电位反应中,雄性红脂大小蠹对油松挥发性物质中(S)-(-)-α-蒎烯、柠檬烯和(S)-(+)-3-蒈烯的反应较为强烈,而雌性红脂大小蠹对油桦挥发性物质中(S)-(+)-3-蒈烯、柠檬烯、(S)-(-)-α-蒎烯和得叶烯的反应较为强烈。雌性红脂大小蠹较雄性红脂大小蠹对这些挥发性物质更为敏感。寄生于我国油松的红脂大小蠹对树体挥发物的反应与原产地美国有较大的差异,产生变化可能与寄主挥发物成分和环境变化有关,但其机制还有待于进一步研究。

Abstract:

The volatile compositions of Chinese Pine (Pinus tabulaeformis) are analyzed. The main turpentine volatiles are ?-(+)-α-pinene, (S)-(-)-β-pinene, (S)-(+)-3-carene (the largest) which occupy more than 97% of the total. There are also myrcene, (+)-limonene, camphene, terpinen and phellandrene. In the experiment of Electroantennograms(EAG), the male of red turpentine beetles are sensitive to (S)-(-)-α-pinene、limonene and (S)-(+)-3-carene; while the female of the red turpentine beetles are sensitive to (S)-(+)-3-carene、limonene、(S)-(-)-α-pinene and myrcene. The female are more sensitive to the volatiles than the male. There is much difference in response of Dendroctonus valens in Chinese pine compared to that in USA in ponderosa pine. The volatile difference of the two pine species and the environment condition may contribute to this change. Further study on the mechanism of the change is needed.
