先天偏好促进了传粉者寻找花朵的能力。蜜蜂和大黄蜂对“蓝色”刺激有强烈的偏好，这种颜色的花通常能提供更高的花蜜奖励。有趣的是，来自世界各地多个不同地点的花在蜜蜂颜色空间中的独立分布是相同的。然而，目前缺乏关于无刺蜜蜂天生的颜色偏好的数据，而在世界许多地方，无刺蜜蜂通常被认为是关键的传粉者。在澳大利亚，特有的无刺蜜蜂炭黑四角蜂分布广泛，被认为是本地植物和农作物的有效传粉者。在受控的实验室条件下，我们使用代表常见颜色的标准宽带反射刺激测试了na < ve蜜蜂的先天颜色反应。考虑膜翅目动物视觉和六边形色彩空间的比色分析揭示了不同测试群体之间的差异，以及绿色对比度和绿色对比度与光谱纯度的相互作用对蜜蜂选择的显著影响。我们还观察到来自色彩空间的蓝色和蓝绿色分类区域的刺激的颜色偏好。我们的结果讨论了从世界各地蜜蜂授粉观察到的相似的花朵颜色分布。
Innate preferences promote the capacity of pollinators to find flowers. Honeybees and bumblebees have strong preferences for 'blue' stimuli, and flowers of this colour typically present higher nectar rewards. Interestingly, flowers from multiple different locations around the world independently have the same distribution in bee colour space. Currently, however, there is a paucity of data on the innate colour preferences of stingless bees that are often implicated as being key pollinators in many parts of the world. In Australia, the endemic stingless bee Tetragonula carbonaria is widely distributed and known to be an efficient pollinator of both native plants and agricultural crops. In controlled laboratory conditions, we tested the innate colour responses of na < ve bees using standard broadband reflectance stimuli representative of common flower colours. Colorimetric analyses considering hymenopteran vision and a hexagon colour space revealed a difference between test colonies, and a significant effect of green contrast and an interaction effect of green contrast with spectral purity on bee choices. We also observed colour preferences for stimuli from the blue and blue-green categorical regions of colour space. Our results are discussed in relation to the similar distribution of flower colours observed from bee pollination around the world.
