Faculty of Science. - Data provided by Europeana Collections- U radu su prikazani rezultati praćenja širenja areala invazivnih vrsta komaraca Aedes albopictus i Aedes japonicus na području sjeverozapadne Hrvatske od prvog nalaza do kraja 2016. godine. U razdoblju od 2012. do 2015. godine uočeno je invazivno širenje vrste Ae. albopictus na području grada Zagreba gdje je vrsta prvi put pronađena 2004. godine. Zabilježeno je širenje areala vrste i na područje susjednih županija. Vrsta Ae. japonicus prvi put je pronađena u Krapinsko-zagorskoj županiji 2013. godine, a do 2016. godine također se proširila na šire područje sjeverozapadne Hrvatske. Iako istraživane invazivne vrste imaju različite temperaturne zahtjeve, promatrano područje pogoduje udomaćivanju obje vrste. Razdoblje ovipozicije vrste Ae. albopictus kraće je u odnosu na vrstu Ae. japonicus. Testiranjem komaraca na prisustvo arbovirusa, RNA virusa Usutu dokazana je u jednom od ukupno 61 testiranog skupnog uzorka komaraca vrste Ae. albopictus s područja grada Zagreba. RNA virusa West Nile, dengue i chikungunya nije dokazana.- Thesis presents results of the two invasive mosquito species Aedes albopictus and Aedes japonicus spreading in the northwestern Croatia from their first record to the end of 2016. Ae. albopictus species was first recorded in Zagreb in 2004, but invasive spreading throughout the city was recorded during 2012-2015. Moreover, the species has spread to the neighbouring counties. Ae. japonicus species was first recorded in 2013 in Krapina-Zagorje Country, whereas in 2016 it was spread over the wider area of the northwestern Croatia. Although these two invasive mosquito species require somewhat different temperature conditions, climate of the region represents a suitable habitat for both species. The period of seasonal activity of Ae. albopictus is shorter than for Ae. japonicus. Samples of Ae. albopictus were tested for the presence of arboviruses. Usutu RNA was detected in one of 61 tested mosquito pools from Zagreb area. West Nile, dengue and chikungunya viral RNA was not detected.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.
