有刺昆虫的颜色通常是基于对比的浅色和黑色色素图案，作为对捕食者的警告信号。然而，在许多社会黄蜂物种，地理变异大大修改这个信号通过黑素多态性可能驱动不同的选择压力。到目前为止，令人惊讶的是知之甚少的地理变化的社会黄蜂的着色有关的警戒和黑化和遗传和发育的限制。本研究的主要目的是提高社会黄蜂物种内的颜色变化的描述，并确定哪些因素是驱动这种变化。因此，我们探讨了进化历史的多态性黄蜂，胡蜂velutina Lepeletier，1836年，使用线粒体和微卫星标记，我们分析了其黑变的颜色空间的基础上描述的身体部位着色。我们在该物种中发现了两个主要谱系，并证实了之前的同义词V. auraria Smith，1852，在V. velutina下，仅在颜色上有所不同。我们还发现，大多数身体部位的黑变是正相关的，与一些部分形成潜在的颜色模块。最后，我们表明，群体之间的颜色的变化是不相关的分子，地理或气候差异。我们的观察结果表明，黄蜂的着色模式和它们的地理变异是由基因与发育限制的影响。我们的研究结果还强调，胡蜂velutina人口经历了几个收敛的颜色的演变，更有可能的影响，由aposematism和Müllerian拟态比非生物的压力上黑化的限制。
Coloration of stinging insects is often based on contrasted patterns of light and black pigmentations as a warning signal to predators. However, in many social wasp species, geographic variation drastically modifies this signal through melanic polymorphism potentially driven by different selective pressures. To date, surprisingly little is known about the geographic variation of coloration of social wasps in relation to aposematism and melanism and to genetic and developmental constraints. The main objectives of this study are to improve the description of the colour variation within a social wasp species and to determine which factors are driving this variation. Therefore, we explored the evolutionary history of a polymorphic hornet, Vespa velutina Lepeletier, 1836, using mitochondrial and microsatellite markers, and we analysed its melanic variation using a colour space based on a description of body parts coloration. We found two main lineages within the species and confirmed the previous synonymy of V. auraria Smith, 1852, under V. velutina, differing only by the coloration. We also found that the melanic variation of most body parts was positively correlated, with some segments forming potential colour modules. Finally, we showed that the variation of coloration between populations was not related to their molecular, geographic or climatic differences. Our observations suggest that the coloration patterns of hornets and their geographic variations are determined by genes with an influence of developmental constraints. Our results also highlight that Vespa velutina populations have experienced several convergent evolutions of the coloration, more likely influenced by constraints on aposematism and Müllerian mimicry than by abiotic pressures on melanism.
