The yellow-fever mosquito Aedes aegypti is a major vector of human diseases, such as dengue, yellow fever, chikungunya and West Nile viruses. Chemoreceptor organs on the labella and tarsi are involved in human host evaluation and thus serve as potential foci for the disruption of blood feeding behavior. In addition to host detection, these contact chemoreceptors mediate feeding, oviposition and conspecific recognition; however, the molecular landscape of chemoreception in these tissues remains mostly uncharacterized. Here we report the expression profile of all putative chemoreception genes in the labella and tarsi of both sexes of adult Ae. aegypti and discuss their possible roles in the physiology and behavior of this important disease vector.
黄热病蚊子埃及伊蚊是人类疾病的主要传播媒介，如登革热、黄热病、基孔肯雅热和西尼罗河病毒。唇须和跗节上的化学感受器器官参与对人类宿主的评估，因此是扰乱吸血行为的潜在靶点。除了宿主检测外，这些接触化学感受器还介导进食、产卵和同种识别；然而，这些组织中化学感受的分子情况仍大多未被描述。在此，我们报告了成年埃及伊蚊雌雄两性唇须和跗节中所有假定化学感受基因的表达谱，并讨论了它们在这种重要疾病媒介的生理和行为中的可能作用。
