General description
月桂是单萜。 Ips spp 的雄性在暴露于月桂烯蒸汽时产生信息素齿小蠹二烯醇（2-甲基-6-亚甲基-2,7-辛二烯-4-醇）和/或齿小蠹烯醇（2-甲基-6-亚甲基-7-辛烯-4-醇）。月桂烯是萜烯醇的前体。月桂是甲虫宿主的组成部分——西黄松。钌、铬、铱和铑络合物催化月桂烯加氢生成单氢化产物、二氢化产物和三氢化产物的复杂混合物。
Application
月桂烯是通过 GC-MS 鉴别 E -月桂醇（2-甲基-6-亚甲基- E -2,7-辛二烯-1-01）作为欧亚树皮甲虫重齿小蠹后肠主要成分的合适合成标准品。

In the field, both sexes of the western pine beetle, Dendroctonus brevicomis, are attracted by the female-produced bicyclic ketal exo-brevicomin; this response is enhanced by myrcene (a constituent of the beetle's host, ponderosapine), which is not an attractant by itself.
Selective hydrogenation of myrcene catalyzed by complexes of ruthenium, chromium, iridium and rhodium.

We studied the effects of water stress, fertilization and time course on foliar volatile terpene emission rates by Quercus ilex and Pinus halepensis in a garden experiment. The terpenes mostly emitted by both species were alpha-pinene, beta-pinene, beta-myrcene and Delta(3)-carene.
