摘要

在昆虫中,成虫在发育过程中因暴露于寒冷环境而产生的深色色素沉着是普遍存在的。我们探讨了与昆虫颜色可塑性有关的两个假设。首先,如果黑色素色素的合成成本很高,需要分配资源,那么黑色素的增加应该与表现性状呈负相关(成本假说)。其次,鉴于某些物种的黑色素化与免疫反应或抗干燥性呈正相关,黑色素化与表现可能呈正相关(正协方差假说)。此外,考虑到雌性和雄性在繁殖努力和活动方面的典型差异,我们预计这些表现与黑色化之间的关系在雌雄之间会有所不同。在大多数测试温度下(15、20、25、30 和 35°C),黑色化几乎不能解释标准代谢率的变化。在飞行性能方面,经过低温饲养后,浅色雌甲虫的飞行速度比深色雌甲虫快,而雄性甲虫则相反。结果表明,至少某些飞行性能成本与发育诱导的黑色化有关,支持了成本假说。雄性和雌性之间在这些关系上的差异表明,不同性别之间黑色化变化的驱动因素是不同的。重要的是,在温暖环境中饲养的雌性个体与同等条件下饲养的雄性个体以及冷环境中饲养的个体相比,其黑色素变异更为严重。我们提出了新的方向,以检验与自然界中性别间颜色变化和表现的维持有关的假设。

期刊介绍: Ecological Entomology publishes top-quality original research on the ecology of insects and related invertebrate taxa. Our aim is to publish papers that will be of considerable interest to the wide community of ecologists who are motivated by ecological or evolutionary theory. The suitability of a manuscript will usually be assessed within 5 days. We publish full-length Original Articles as well as Reviews, Short Communications, Methods and Natural History papers. In Original Articles, we greatly prefer papers that test specific hypotheses and which have a high degree of novelty. All categories aim for innovative contributions that advance the subject of ecological entomology.
