The researchers examined how short-term (one generation) and long-term (ten generations) exposure to a higher temperature (32°C/26°C day/night cycle) influences mosquito tolerance and resistance to CFAV infection, as well as their overall fitness. The key findings reveal that prolonged heat exposure leads to increased viral tolerance in mosquitoes without significant fitness costs, while short-term heat exposure results in increased resistance but at the expense of mosquito fitness. These findings have significant implications for understanding the effects of climate change on arbovirus transmission dynamics and the evolution of both mosquito vectors and the viruses they carry.Main Themes and Important Ideas/Facts:Climate Change and Arbovirus Transmission:The study highlights the complex interplay between climate change, mosquito biology, and virus interactions, emphasizing the relevance of this research to the prevalence and transmission dynamics of arboviruses like dengue, Zika, and chikungunya, which threaten billions globally.\"Current anthropogenic climate change has profound and complex impli-cations for the prevalence and the transmission dynamics of arboviruses such as dengue, Zika and chikungunya, which are an impending risk for 3.9 billion people in tropical and subtropical areas of the world.\"Rising...","thumbnail_url":"https://img.transistorcdn.com/qJYlR2Phxe3IMx6KHnsmKp1D71DIqj8LuYMSrDKo9Jc/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS82MDgx/MDIyNmJkNWU5YmIz/NzJhZDVmZjYyOGZi/NTgxMi53ZWJw.webp","thumbnail_width":300,"thumbnail_height":300}
