本文研究了侧柏树皮挥发油对双条杉天牛的引诱作用。利用冷阱和水蒸气蒸馏法提取挥发油,用硅胶往层析分离提取物得到的活性组分进行了室内室外引诱活性测定。结果表明:侧柏挥发油对双条杉天牛雌雄成虫有强烈的引诱作用。其活性成分含有α—蒎烯、β—菠烯、α—侧柏烯、α—葑烯、冬青油烯、α—月桂烯、Δ~3-蒈烯、α-松油烯、对伞花烃、柠檬烯、γ一松油烯、萜品油烯和斧柏烯。其中α—蒎烯、β—蒎烯以及两者的1:1混合物对双条杉天牛无引诱作用。
In this paper, we studied the lure effect of the essential oil of Arborvitae bark on Cunninghamia lanceolata. The volatile oil was extracted by cold trap and steam distillation, and the active components of the extract were separated by silica gel chromatography to determine the indoor and outdoor attractant activity. The results showed that the volatile oil of Arborvitae had a strong attraction to male and female adults of Cunninghamia lanceolata. The active ingredient contains α-pinene, β-pinene, α-orientin, α-camphene, myrcene, α-myrcene, Hydrocarbons, limonene, gamma-terpinene, terpinolene and axene. Among them, α-pinene, β-pinene and a 1: 1 mixture of the two had no attraction to Cunninghamia lanceolata.
