Many hematophagous insects acquire medical and veterinary relevance because they transmit disease causing pathogens to humans. Hematophagy is only fulfilled once a blood feeder successfully locates a vertebrate host by means of fine sensory systems. In nature, blood-sucking insects can exploit environments with differential association with their hosts. Given the relevance of the sensory systems during host searching, we review the current state of knowledge of the sensory machinery of four blood-sucking insects: human lice, bed bugs, kissing bugs and mosquitoes. Each one is representative of highly anthropophilic behaviours and a different degree of association with human hosts. We compare the number, arrangement and functional type of cuticular sensory structures dispersed on the main sensory organs. We also compare the genetic machinery potentially involved in the detection of host stimuli. Finally, we discuss the sensory diversity of the insects studied here.
许多吸血昆虫因其传播致病病原体给人类而具有医学和兽医方面的重要性。只有当血液摄取者通过精细的感觉系统成功定位脊椎动物宿主时，才会完成吸血行为。在自然界中，吸血昆虫可以利用与宿主不同的环境。鉴于在宿主搜索过程中感觉系统的重要性，我们回顾了四种吸血昆虫（人虱、臭虫、接吻虫和蚊子）的感觉机制的最新知识。每一种都代表了高度嗜人的行为和与人类宿主不同程度的关联。我们比较了分布在主要感觉器官上的表皮感觉结构的数量、排列和功能类型。我们还比较了潜在参与宿主刺激检测的遗传机制。最后，我们讨论了这里研究的昆虫的感觉多样性。
