Aedes aegyti and Ae. Albopictus are major vectors of arboviruses such as Chikungunya virus, dengue virus, Rift Valley fever virus, yellow fever virus, and Zika virus. Vector control of Aedes using insecticides is important in the control of the transmission of these viruses to humans but these efforts are threatened globally by the emergence of insecticide resistance. This review focuses on cases of insecticide resistance in Aedes to the four classes of insecticides approved by World Health Organisation (WHO) for vector control. Studies show that Aedes aegypti and Aedes albapictus have developed resistance to all the classes of insecticide in various locations. However, few studies in Pakistan showed that some areas Aedes are susceptible to Carbamate. Therefore, to avoid re-emergence of arbovirus epidemics, insecticide resistance should be continued to monitor. Once insecticide resistance is established in a population, there is a real danger of the re-emergence of vector-borne diseases that had been presumed to be under control. There is also an emergency demands for new active ingredients based on novel modes of action or insecticidal compounds acting on new binding sites in already established targets in order to diversify the means of the vector control and to prolonged the life span of all the available insecticides, thereby reducing the risk of insecticide resistance leading to re-emerging arbovirus diseases.
