Aculeata 的衰落引起了人们对其保护和维持其作为重要传粉媒介的功能的担忧。盘诱是监测这些生物体最常用的方法之一。许多研究人员建议除了黄色陷阱之外还使用多种颜色的盘陷阱。在这里，我们通过分析使用白色、黄色、绿松石色和粉色盘式诱捕器获得的来自 356 种蜜蜂和黄蜂的 5,421 只个体，提供了有关欧洲 Aculeata 颜色偏好的第一个数据。白色和黄色陷阱的总捕获率和多样性高于绿松石色和粉色陷阱。物种特异性丰度并不跟随总捕获率的变化。然而，只有 7 种（96 个最常捕获的物种中）在黄色诱捕器中以较低的捕获率捕获，但在白色诱捕器中以较高的捕获率捕获。只有两个物种（Apis mellifera 和 Priocnemis minuta）比白色或黄色陷阱更容易被捕获。重要的是，在评估通过盘诱获得的Aculeata的性别比例时需要谨慎，因为许多Aculeata表现出性别特异性的颜色偏好。例如，在 Dasypoda hirtipes 中，我们在黄色诱捕器中捕获了 16 只雄性中的 14 只，但在绿松石诱捕器中捕获了 38 只雌性中的 34 只。我们提供的实验证据表明，许多寡聚蜜蜂（在一些特定植物物种上为它们的巢收集花粉）的雌性比它们的雄性表现出更严格的诱捕颜色偏好，这与它们观察到的花颜色偏好相关。
The decline of Aculeata has raised concerns regarding their conservation and the maintenance of their function as important pollinators. Pan trapping is among the most frequently used methods for monitoring these organisms. Numerous researchers have suggested using pan traps of multiple colors in addition to the yellow traps. Here we provide the first data for the color preferences of European Aculeata by analyzing 5,421 individuals from 356 species of bees and wasps obtained using white, yellow, turquoise and pink pan traps. The total capture rates and diversity were higher in the white and yellow traps over the turquoise and pink ones. The species-specific abundance did not follow changes in the total capture rates. Nevertheless, only seven (of the 96 most commonly captured species) were captured at low rates in the yellow traps, but were obtained at high rates in the white traps. Only two species (Apis mellifera and Priocnemis minuta) were captured preferentially to other than white or yellow traps. Importantly, caution is needed when assessing the sex ratios of Aculeata obtained by pan trapping because many Aculeata display sex-specific color preferences. For example, in Dasypoda hirtipes, we captured 14 of 16 males in the yellow traps, but obtained 34 of 38 females in the turquoise traps. We provide experimental evidence that the females of numerous oligolectic bees (collecting pollen for their brood on a few specific plant species) display more stringent trap color preferences than their males, which correlates with their observed flower color preferences.
