The volatile secretion emanating from the cephalic part of the paired labial gland in male bumblebees of three North American species, viz. Bombus sonorus Say, Bombus huntii Greene and Psithyrus insularis (F. Smith) has been analysed by GC-MS and GC-FTIR. The secretion, which is deposited as a marking secretion on various objects along a repetitive flight path, is composed of isoprenoids, (acyclic sesqui- and diterpenes) and straight-chain fatty acid derivatives (alcohols containing 14, 16 and 18 carbon atoms, and odd numbered hydrocarbons ranging from 23 to 27 carbons). The secretions are species-specific with just a few major components. In B. sonorus (Z)-11-octadecen-1-ol is the main compound accompanied by geranylgeraniol and tetradecan-1-ol; in B. huntii the dominating compound is trans-2,3-dihydrofarnesol and it also contains (Z)-11-octadecen-1-ol and hexadecan-1-ol; P. insularis is characterized by geranylcitronellol, together with the (Z)-11-octadecen-1-ol and hexadecan-1-ol. These results agree with analyses of 36 species and two forms of Scandinavian bumblebees analysed previously.
对北美三种雄蜂，即熊蜂（Bombus sonorus Say）、亨氏熊蜂（Bombus huntii Greene）和岛屿拟熊蜂（Psithyrus insularis (F. Smith)）成对唇腺头部产生的挥发性分泌物进行了气相色谱-质谱联用（GC-MS）和气相色谱-傅里叶变换红外光谱联用（GC-FTIR）分析。这种分泌物作为标记分泌物沉积在沿重复飞行路径的各种物体上，由类异戊二烯（无环倍半萜和二萜）和直链脂肪酸衍生物（含14、16和18个碳原子的醇，以及碳数从23到27的奇数碳氢化合物）组成。这些分泌物具有物种特异性，只有少数几种主要成分。在熊蜂中，（Z）-11-十八碳烯-1-醇是主要化合物，伴有香叶基香叶醇和十四烷-1-醇；在亨氏熊蜂中，主要化合物是反式-2,3-二氢法尼醇，它还含有（Z）-11-十八碳烯-1-醇和十六烷-1-醇；岛屿拟熊蜂的特征是香叶基香茅醇，以及（Z）-11-十八碳烯-1-醇和十六烷-1-醇。这些结果与之前对36种和两种斯堪的纳维亚熊蜂的分析结果一致。
