Abstract: Climate change, driven by global warming, is impacting public health by increasing arbovirus transmitted by Aedes aegypti. Indiscriminate insecticide use has selected resistant populations, threatening vector control efforts. We characterized Ae. aegypti populations from the Amazon, Caatinga, and Atlantic Forest biomes, analyzing life-history traits and insecticide resistance. Results revealed regional adaptations, including thermal stress resistance and insecticide resistance, with high levels of kdr mutations. These findings highlight the need for region-specific vector control strategies.
