Abstract

The volatile components of the Dufour's gland secretion of female halictid bees have been examined in 18 Nearctic species belonging toAgapostemon, Augochlora, Augochlorella, Augochloropsis, Dialictus, Evylaeus, Halictus, andLasioglossum. Nine saturated and unsaturated macrocyclic lactones ranging from C18 to C26 have been identified. Four of these compounds, the saturated C26 and the unsaturated C20, C22, and C24 lactones, are new natural products reported for halictine bees. A series of eight esters containing branched C5-alkenols and fatty acids has been identified in several species. The cell linings and pollen ball inAugochlora pura pura contain the same major lactones as the Dufour's gland. A discussion of the significance of the Dufour's gland secretion for apoid systematics and its function in the Halictidae is presented.

摘要

已对 18 种属于 Agapostemon、Augochlora、Augochlorella、Augochloropsis、Dialictus、Evylaeus、Halictus 和 Lasioglossum 的近北极地区的雌性叶蜂的 Dufour 腺分泌物的挥发性成分进行了研究。已经鉴定出 9 种从 C18 到 C26 的饱和和不饱和大环内酯。其中四种化合物，即饱和的 C26 和不饱和的 C20、C22 和 C24 内酯，是叶蜂中新报道的天然产物。在几个物种中已经鉴定出一系列含有支链 C5-烯醇和脂肪酸的八种酯。Augochlora pura pura 的细胞衬里和花粉球含有与 Dufour 腺相同的主要内酯。本文讨论了 Dufour 腺分泌物对蜂科系统学的意义及其在叶蜂科中的功能。
