Distribution of Aedes () cretinus in Türkiye.

Objective: , a white and black stripped , shares morphological similarities with and which are among the most important vectors and invasive species in the world. Due to its limited distribution and low population density, information on the biology and ecology of the species has been limited so far. This study aimed to determine distribution of Ae. in Türkiye.

Methods: Field works have been carried out in the Mediterranean, Aegean and Marmara Regions of Türkiye. Larval samples were collected by larval dippers while adult mosquito catches were performed using the human landing catch method and CDC-light traps.

Results: A total of 44 different Ae. populations were identified in the Mediterranean, Aegean and Marmara Regions of Türkiye. The larval specimen collected from small containers, tires, tree holes and natural small habitats. A plane (), walnut (), Türkiye oak (), chestnut () and cedar () tree holes are the main larval habitats in which the specimen collected. In some localities, larvae were found together with , and larvae in tree holes. Human landing catch method captured a greater number of females than CDC-light traps.

Conclusion: This study determined the distribution of Ae. in Türkiye for the first time. Information on respective geographic distribution of Ae. is fundamental for effective control programmes. Further studies are needed to understand the biology and ecology of these species.
