The volatile components of Dufour's gland extracts were analyzed in four species of NearcticNomia bees;Nomia (Dieunomia)heteropoda, N. (Tetrazonata)tetrazonata, N. (Epinomia)nevadensis, andN. (Epinomia)triangulifera. A homologous series of five saturated macrocyclic lactones ranging from C18 to C26 was identified. A series of esters (branched C5-alkenols and fatty acids) was also identified in all species investigated. Two of these esters are new natural products reported for bees. A discussion of the significance of the Dufour's gland secretion for halictid systematics and its function in the Halictidae is also presented.
对四种北美无刺实蝇属蜜蜂（无刺实蝇属（双环属）异足亚种、无刺实蝇属（四元属）四元亚种、无刺实蝇属（埃皮诺米亚属）内华达亚种和无刺实蝇属（埃皮诺米亚属）三角亚种）的杜福尔氏腺提取物的挥发性成分进行了分析。鉴定出了一系列从 C18 到 C26 的五种同系饱和大环内酯。在所有研究的物种中还鉴定出了一系列酯类（支链 C5-烯醇和脂肪酸）。其中两种酯是报道的蜜蜂的新天然产物。还讨论了杜福尔氏腺分泌物对螯蜂系统发育的意义及其在螯蜂科中的功能。
