雄性兰花蜂（Euglossini）从它们的环境中收集挥发物来调制物种特异性的“香水”，这些香水随后在交配地点散发出来。香水的强度、复杂性或成分可能会编码男性的年龄（生存），但个人香水如何随着时间的推移而发展需要澄清。我们研究了储存过程中的化学变化。我们将八种香料化合物的混合物注入Euglossa imperialis的口袋中，只有两种最挥发性的化合物在12天内减少。使用不同的方法，我们发现在10天内Euglossa championi的天然存在的香料化合物的量的显著变化，其中高度挥发性的次要化合物（例如单萜）的最强降低（高达70%峰面积），以及一些倍半萜类化合物的显著增加（高达40%）。在干蜜蜂的腿中观察到相应的变化，表明所观察到的变化发生不需要代谢活动。我们的研究结果证实，雄性兰花蜜蜂通常善于保存收集的香水。然而，混合物中的较重化合物可能在个体蜜蜂的一生中发生微妙的变化，例如由于蒸发或口袋内的化学反应，老年雄性在其调味香水中获得更明显的基调。
Male orchid bees (Euglossini) collect volatiles from their environment to concoct species-specific “perfumes”, which are later emitted at mating sites. Intensity, complexity or composition of perfumes may encode age (survival) of a male, but how the individual perfume develops over time needs to be clarified. We investigated chemical changes during storage in leg pockets. We injected a mixture of eight perfume compounds into pockets of Euglossa imperialis and only the two most volatile compounds decreased over 12 days. Using a different approach we found significant shifts in quantities of naturally occurring perfume compounds of Euglossa championi over 10 days, with the strongest decreases (up to 70% peak area) in highly volatile minor compounds, e.g. monoterpenes, and noteworthy increases (up to 40%) in some sesquiterpenoids. Corresponding shifts were observed in legs of dried bees, suggesting that no metabolic activity is required for the observed changes to occur. Our results confirm that male orchid bees are generally good at preserving collected perfumes. However, subtle shifts towards heavier compounds in blends may occur over the lifetime of individual bees, e.g. due to evaporation or in-pocket chemical reaction, with old males acquiring a more pronounced base note in their seasoned perfumes.
