When the tree changes from health to weak, the main terpene compounds changed, such as the amount of 3-carene, isolimonene,β-pinene, 4-carene were significantly enhanced, and santolina triene,α-fenchene,β-myrcene,β-phellandrene were declined. It will provide a basis for Monochamus urussovi Fischer to select suitable parasitic Picea jezoensis.

鱼鳞云杉树势由健康向衰弱转变时，主要烯萜类化合物含量发生变化，3-蒈烯、异柠檬烯、β-蒎烯、4-蒈烯、α-蒎烯等含量显著上升，而神圣亚麻三烯、α-葑烯、β-月桂烯、β-水芹烯等含量下降，这些烯萜类化合物的变化，为云杉大黑天牛定位选择适宜寄生的鱼鳞云杉提供了依据。

The main components of santolina essential oil are artemisia ketone; vulgarone;β-Phellandrene; curcumene; myrcene; sabinene; and β-Pinene, accounting for 83.44 percent of the total content and 887.5μL/kg·FW in terms of absolute content.

Electroantennogram study showed that the female moths had stated response to main compositions of needle volatile of α-pinene,β-pinene, myrcene, limonene and β-phellandrene,β-phellandrene elicited the largest EAG response, and limonene was secondly.

松实小卷蛾雌蛾对思茅松针叶挥发性物质主要成分α-蒎烯、β-蒎烯、月桂烯、柠檬烯、β-水芹烯都表现出一定的触角电位反应，以β-水芹烯引起的松实小卷蛾触角电位反应最大，其次是柠檬烯。

Compared with the control,the relative contents of 3-Carene and thujopsene increased significantly and that ofα-Pinene、β-phellandrene、β-Pinene and Limonene decreased in weak trees.

但是衰弱侧柏中3-蒈烯和罗汉柏烯含量明显升高，α-蒎烯、β-蒎烯、β-水芹烯和柠檬烯含量减低。

Conclusion］Taking into account the fact that there is more β-phellandrene and limonene in volatile of fresh needles than that of withered needles, the two compounds are speculated as the primary oviposition stimulants.

结论］β-水芹烯、柠檬烯在新鲜针叶挥发物中的含量远大于在枯萎针叶挥发物中的含量，β-水芹烯、柠檬烯可能是刺激松实小卷蛾雌蛾产卵的主要物质。

Gas chromatography and mass spectrometry technique were employed to analyze the ginger oleoresin. This analysis resulted in the detection of 3 hitherto unknown natural compounds, 24 compounds previously reported as pungent compounds and 50 volatile compounds from ginger. The volatile compounds were mainly α-zingiberene (22.29%),β-sesquiphellandrene (8.58%),α-farnesene (3.93%),β-bisabolene (3.87%),α-curcumene (2.63%), which were mostly consisted of sesquiterpene hydrocarbons.
