蚊子利用各种各样的线索来寻找宿主，最终导致病原体的传播。其中，嗅觉线索（例如，寄主散发的气味，包括CO2和皮肤挥发物）在调节寄主寻找行为中起着核心作用。虽然蚊子的嗅觉可能受到许多因素的影响，例如昆虫的生理状态（例如，年龄、生殖状态），环境温度对嗅觉系统的影响仍然未知。在这项研究中，我们量化了埃及伊蚊，登革热，黄热病和寨卡病毒等病原体的载体，在不同的环境温度下对宿主和植物相关气味的行为反应。
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 (e.g., host-emitted odors, including CO2, 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 (e.g., age, reproductive state), the impact of environmental temperature on the olfactory system remains unknown. In this study, we quantified the behavioral responses ofAedes aegyptimosquitoes, vectors of dengue, yellow fever, and Zika viruses, among other pathogens, to host and plant-related odors under different environmental temperatures.
