Mitochondrial cytochrome oxidase I variation in Asian tiger mosquito (Aedes albopictus): Determination of the different and multiple introduction situations in Turkiye

Aedes (Stegomyia) albopictus (Skuse, 1894) is an invasive mosquito species that can transmit many arboviral diseases. In Turkiye, this was found first in Thrace 2011, then the Eastern Black Sea 2014, and Aegean regions 2018. We analyzed COI gene region of 554 samples from 13 different locations Sea, Aegean, Marmara to determine diversity possible introduction origin A. Türkiye. Three haplotypes derived two segregation sites were detected, Hd π values 0.175 0.00029, respectively. Hap_1 a common haplotype detected all regions. Hap_2 regions, while Hap_3 rare, recorded only lineages. pairwise FSTs geographical populations, lineages statistically (except Mugla samples). AMOVA test results indicated significant differences between three studied (df = 2, f 0.01784). Although Turkish appear have originated temperate Northern Italy may mix Albania lineages, revealed multiple events via various routes.
