Mosquitoes are emerging as model systems with which to study innate behaviours through neuroethology and functional genomics. Decades of work on these disease vectors have provided a solid behavioural framework describing the distinct repertoire of predominantly odour-mediated behaviours of female mosquitoes, and their dependence on life stage (intrinsic factors) and environmental cues (extrinsic factors). The purpose of this review is to provide an overview of how intrinsic factors, including adult maturation, age, nutritional status, and infection, affect the attraction to plants and feeding on plant fluids, host seeking, blood feeding, supplemental feeding behaviours, pre-oviposition behaviour, and oviposition in female mosquitoes. With the technological advancements in the recent two decades, we have gained a better understanding of which volatile organic compounds are used by mosquitoes to recognise and discriminate among various fitness-enhancing resources, and characterised their neural and molecular correlates. In this review, we present the state of the art of the peripheral olfactory system as described by the neural physiology, functional genomics, and genetics underlying the demonstrated changes in the behavioural repertoire in female mosquitoes. The review is meant as a summary introduction to the current conceptual thinking in the field.

调节蚊子的气味引导行为

蚊子正在成为通过神经行为学和功能基因组学研究先天行为的模型系统。数十年对这些疾病媒介的研究提供了一个坚实的行为框架,描述了雌性蚊子主要由气味介导的行为的独特特征,以及它们对生命阶段(内在因素)和环境线索(外在因素)的依赖性。本综述的目的是概述内在因素,包括成虫成熟、年龄、营养状况和感染,如何影响对植物的吸引力和以植物液体为食、寄主寻找、血液喂养、补充喂养行为、预喂养行为。产卵行为和雌性蚊子的产卵。随着近二十年来技术的进步,我们对蚊子利用哪些挥发性有机化合物来识别和区分各种增强健康的资源有了更好的了解,并表征了它们的神经和分子相关性。在这篇综述中,我们介绍了外周嗅觉系统的最新技术,如神经生理学、功能基因组学和遗传学所描述的,这些系统是雌性蚊子行为变化的基础。该评论旨在总结介绍该领域当前的概念思维。
