Mosquitoes use a wide range of cues to find a host to feed on, eventually leading to the transmission of pathogens. Among them, olfactory cues ( , host emitted odors, including CO , and skin volatiles) play a central role in mediating host seeking behaviors. While mosquito olfaction can be impacted by many factors, such as the physiological state of the insect ( , age, reproductive state), the impact of environmental temperature on the olfactory system remains unknown. In this study, we quantified the behavioral responses of mosquitoes, vectors of dengue, yellow fever and Zika viruses, to host and plant related odors under different environmental temperatures.
蚊子利用多种线索来寻找宿主进食，最终导致病原体的传播。其中，嗅觉线索（如宿主散发的气味，包括二氧化碳和皮肤挥发物）在介导宿主寻找行为中起着核心作用。虽然蚊子的嗅觉会受到许多因素的影响，如昆虫的生理状态（如年龄、生殖状态），但环境温度对嗅觉系统的影响仍然未知。在本研究中，我们量化了登革热、黄热病和寨卡病毒的传播媒介蚊子在不同环境温度下对宿主和植物相关气味的行为反应。
