The Culicomorpha are an infraorder of several families of blood-feeding flies, including mosquitoes (Diptera: Culicidae). Here we discuss the evolutionary origins of blood-feeding within the Culicomorpha and review literature that suggests this behaviour may have evolved from ancestral plant-feeding or a combination of plant-feeding and insect-feeding. Sialomic and life-history evidence suggest that plant-feeding, concurrent or not with insect-feeding, is parsimonious as an ancestral diet for Culicomorpha. We review the chemical parsimony observed between vertebrate headspace odours, floral headspace odours, and honeydew headspace odours, which are behaviourally attractive to many of the Culicomorpha. We also review the sensory and neural mechanisms involved in changes in olfactory attraction and we propose this observed chemical parsimony as a hypothesis for an associative mechanism which may have led to the development of blood-feeding from plant-feeding that is consistent with a 'path of least resistance' for the sensory changes necessary to undergo host shifts.
蚋总科是吸血蝇类的一个亚目，包括蚊子（双翅目：蚊科）。在这里，我们讨论了蚋总科内吸血行为的进化起源，并回顾了一些文献，这些文献表明这种行为可能是从祖先的植物食性或植物食性和昆虫食性的结合进化而来的。唾液和生活史的证据表明，以植物为食，同时或不与昆虫食性共存，是蚋总科的一种简单的祖先饮食。我们回顾了脊椎动物头部气味、花部气味和蜜露部气味之间观察到的化学简约性，这些气味对许多蚋总科昆虫具有行为吸引力。我们还回顾了嗅觉吸引力变化所涉及的感觉和神经机制，并提出了这种观察到的化学简约性作为一种假设，即一种联想机制，可能导致从植物食性向吸血性的发展，这与宿主转移所需的感觉变化的“最小阻力路径”是一致的。
