Mosquitoes belonging to the genus Aedes pose a significant threat to human health on a global scenario due to their role in transmission of dengue, chikungunya, zika, and yellow fever. In absence of specific medications and vaccines against these diseases, disease prevention relies on vector control. However, in today's world, vector control is facing major challenges due to the onset of insecticide resistance in mosquitoes. There are four main mechanisms of insecticide resistance, namely, behavioral resistance, reduced penetration/cuticular resistance, metabolic detoxification, and target site resistance; however, the latter two mechanisms have been studied widely in Aedes mosquitoes. Insecticide resistance in Aedes mosquitoes is widespread throughout the world. This review compiles the degree of insecticide resistance/susceptibility prevailing among different field populations of Aedes mosquitoes worldwide. In addition, the review has detailed the mechanisms providing the resistance phenomenon observed in nature in Aedes mosquitoes.
