Tracing temporal and geographic distribution of resistance to pyrethroids in the arboviral vector < i > Aedes albopictus < /i >

ConclusionsHere we provide the most-up-to-date survey on the geographic and temporal distribution of pyrethroid-predictive mutations inAe.albopictus by combiningkdr genotyping on current and historical samples with published data. While we confirm low levels of pyrethroid resistance in most analyzed samples, we find increasing frequencies of F1534C/S and V1016G in China and Greece or Italy, respectively. The observed patterns ofkdr allele distribution support the hypothesis that on site emergence of resistance has contributed more than spread of resistance through mosquito migration/invasions to the current widespread ofkdr alleles, emphasizing the importance of local surveillance programs and resistance management.
