The macrocyclic lactones found in the Dufour's gland of the halictine beeLasioglossum zephyrum are female sex pheromones. Octadecanolide, eicosanolide, docosanolide, and tetracosanolide, as well as monounsaturated homologs of each, are components of the Dufour's gland secretion of this species. Furthermore, a series of odd-carbon-numbered saturated and unsaturated hydrocarbons and isopentenyl docosanoate occur in extracts of the Dufour's gland and of whole females. Two different mixtures of all four synthetic lactones, and additionally a treatment consisting of the natural extract, elicit higher response levels than two of the lactones separately or either of the controls.
在螯蜂科的拉索氏唇舌蜂（Lasioglossum zephyrum）的杜氏腺中发现的大环内酯是雌性信息素。十八烷内酯、二十烷内酯、二十二烷内酯和二十四烷内酯，以及每种物质的单不饱和同系物，都是该物种杜氏腺分泌物的组成部分。此外，在杜氏腺和整只雌性蜂的提取物中还存在一系列奇数碳数的饱和和不饱和烃以及异戊二烯二十二烷酸酯。四种合成内酯的两种不同混合物，以及由天然提取物组成的一种处理方式，比两种内酯单独使用或任何一种对照品的处理方式都能引起更高的反应水平。
