The invasive nature of Aedes albopictus, a competent vector of dengue, zika, yellow fever, and chikungunya viruses, has spread to many parts of the world. To date, there have been no report regarding the insecticide resistance status of Aedes albopictus populations along the Aegean coasts of Turkey. This study aims to confirm the occurrence of Aedes albopictus populations in the Aegean region of Turkey and test their susceptibility against different insecticide classes. Bioassay for susceptibility to Dikloro difenil trikloroetan (DDT) (4%), propoxur (0.1%), fenitrothion (1%), bendiocarb (0.1%), permethrin (0.75%), and deltamethrin (0.05%) of each population was assessed through the World Health Organization (WHO) standard bioassay test. A total of 675 adult Aedes albopictus samples were analysed from four populations in addition to control group and laboratory population. Results showed that all of the populations were resistant or at least possible resistant to DDT. In addition to that, all of the populations showed susceptibility against bendiocarb, propoxur, and fenitrothion except the Didim population, which is a possible resistant to propoxur and fenitrothion and the Bodrum population which is a possible resistant to fenitrothion. Results also indicated reduced mortality against permethrin in the Kuşadası and Güzelçamlı populations, while all of the populations were susceptible to deltamethrin. This study might help public health authorities to choose proper insecticide in control activities before insecticide resistance spread other populations and fix in these populations.
