Abstract Males of many bumblebee species exhibit a conspicuous pre-mating behavior with two distinct behavioral components: scent marking and patrol flying. The marking pheromone is produced by the cephalic part of the labial gland (CLG). As far as is known, the CLG secretion is species specific, and it usually consists of two types of compounds: (i) straight-chain aliphatic alcohols, aldehydes or esters, and (ii) acyclic mono-, sesqui- and diterpenes (alcohols or acetates). Here, we summarize data from the literature reporting chemical composition of the CLG secretions of more than 80 bumblebee species. Similarities and differences within and between subgenera are discussed in the context of biosynthetic pathways and evolution.

性吸引力：大黄蜂雄性信息素综述

摘要 许多大黄蜂物种的雄性表现出明显的交配前行为，具有两种不同的行为成分：气味标记和巡逻飞行。标记信息素由唇腺 (CLG) 的头侧部分产生。据了解，CLG 分泌具有物种特异性，它通常由两种类型的化合物组成：(i) 直链脂肪醇、醛或酯，以及 (ii) 无环单萜、倍半萜和二萜（醇或醋酸盐）。在这里，我们总结了来自报告 80 多种大黄蜂物种 CLG 分泌物化学成分的文献中的数据。在生物合成途径和进化的背景下讨论了亚属内和亚属之间的异同。
