采用气相色谱-质谱联用（GC-MS）技术，对多孔菌科（Polyporaceae）松生层孔菌（Fomitopsis pinicola）和木层孔菌（Fomes fomentarius）子实体挥发性成分进行了分析。F. fomentarius散发出一种更复杂的混合物，含有10种以上的倍半萜。在产孢期，松生镰孢菌释放的（R）-和（S）-辛-1-烯-3-醇、辛-3-酮和一些倍半萜烃类（主要是β-barbatene）增加，而松生镰孢菌释放的β-barbatene增加。在fomentarius中，辛-3-酮、顺式呋喃类芳樟醇氧化物、β-水芹烯、β-月桂烯和几种倍半萜烯烃的释放增加。首次在真菌中鉴定出β-Barbatene。切碎的子实体改变的气味组成更多的F：fomentarius比F：pinicola。测试了五种具有典型真菌气味的挥发物（外消旋-辛-1-烯-3-醇、壬-1-醇、外消旋-辛-3-醇、辛-1-醇和辛-3-酮）在田间对昆虫的吸引力。对三种杂木甲虫Malthodes fuscus、Anaspis marginicollis和A.对赤唇小食心虫及雌雄蛾的引诱作用均为rac-oct-1-en-3-ol。外消旋-1-辛烯-3-醇和辛-3-酮对真菌-昆虫Lordithon lunulatus的多面手捕食作用较强。先前的结果，关于主机特定的吸引力的甲虫发出的气味切碎的子实体的R Pinicola和F。fomentarius进行了讨论，根据这项调查。
Volatiles released from fruiting bodies of the polypores Fomitopsis pinicola and Fomes fomentarius (Polyporaceae) were collected by entrainment and SPME techniques and analyzed by GC-MS. The most significant difference between the two species was found in the terpene fraction. F. fomentarius emitted a more complex blend, with more than 10 sesquiterpenes. During the sporulating phase, the release of (R)- and (S)-oct-1-en-3-ol, octan-3-one, and some sesquiterpene hydrocarbons (mainly beta-barbatene) increased in F: pinicola, whereas in F. fomentarius the release of octan-3-one, cis-furanoid linalool oxide, beta-phellandrene, beta-myrcene, and several sesquiterpene hydrocarbons increased. beta-Barbatene was identified for the first time in fungi. Chopping of the fruiting bodies altered the odor composition more in F: fomentarius than in F: pinicola. Five volatiles giving a typical fungal odor (rac-oct-1-en-3-ol, nonan-1-ol, rac-octan-3-ol, octan-1-ol, and octan-3-one) were tested for insect attraction in the field. Females of the three wood-living generalist beetles Malthodes fuscus, Anaspis marginicollis, and A. rufilabris and both sexes of the moth Epinotia tedella were attracted to rac-oct-1-en-3-ol. The generalist predator on fungus-insects Lordithon lunulatus was attracted to rac-oct-1-en-3-ol and octan-3-one in combination. Previous results regarding the host-specific attraction of beetles to the odors emanating from chopped fruiting bodies of R pinicola and F. fomentarius are discussed in the light of this investigation.
