The two main components of the volatiles from litchi leaves, α-humulene and β-caryophyllene, had no distinct attraction to A. japonicus, but displayed synergistic effect on the host-searching process of natural enemy. 作为荔枝叶片的主要挥发物组分,α-蛇麻烯和β-子丁香烯对平腹小蜂的引诱效果也不明显,但两者在天敌搜索寄主过程中表现为协同作用,并且当均以0.3μl。
Conclusion; Trans-caryophyllene ( 38.41%) was the main constituent, and other constituents include α-gurjunene, caryophyllene oxide, humulene, 9,12-octadecadienoic acid, etc. 结论:主成分为反式-石竹烯(38.41%),其它尚含α-古芸烯、石竹烯氧化物、蛇麻烯、9,12-十八碳二烯酸等。
The major constituents are: β-Caryophyllene, γ-Cadinene, Benzyl benzoate and α-Humulene. 主要成分为:β-石竹烯,杜松烯,苯甲酸苄酯,α-葎草烯等。
