What Do We Know About the Invasive Mosquitoes Aedes atropalpus and Aedes triseriatus?

Abstract

Purpose of Review: Mosquito-borne diseases are a serious concern in Europe since the proliferation of invasive mosquito species increases the risk of epidemics. Aedes spp. (Diptera: Culicidae) are among the most dangerous mosquito vectors in Europe. Among Aedes spp., less attention has been paid to the North American invasive species, Aedes atropalpus and Aedes triseriatus, although these species are vectors of serious diseases. This article aims to provide information about the current status and prospective of these species in Europe. Recent Findings: While the presence of Ae. atropalpus in the European continent is still debated, Ae. triseriatus is no longer present in the European continent, but accidental introductions have been recently reported. Nevertheless, the climatic changes and global market increase the possibility of introduction of North American Aedes species in Europe. Summary: The present article contains a brief overview of the biology, ecology, and vector competence of these two mosquito vectors, outlining their potential to invade new areas and medical importance. We highlighted some bioecological traits that need to be considered to design surveillance programs tailored for these species. Lastly, research challenges aimed to improve basic knowledge and control programs targeting these species are presented.
