Progression du moustique tigre en France : surveillance transfrontalière dans le Grand-Est

Abstract

Vector of chikungunya, dengue and zika viruses, the Asian tiger mosquito Aedes albopictus is also one of the most invasive species in the world. Due to its both biological (resistant and diapausing eggs) and behavioural (following human in their vehicles) characteristics, the tiger mosquito has quickly colonised the whole World through passive dispersal via international trade and travel.Therefore, the invasive mosquitoes including Ae. albopictus are tracked by entomological surveillances at local, national and international scales. The use of ovitraps and citizen reports allows experts to monitor the evolution of its colonisation. Over the last 30 years, the tiger mosquito has established in Europe and settled in France since 2004. Ten years later, it has been detected in the administrative unit of Bas-Rhin (France) which is part of the Upper Rhine valley, a wider area spanning France, Germany and Switzerland. As no administrative borders can prevent invasive mosquitoes' colonisation, this issue has brought together assets of a European collaboration at a cross border scale. Thereby, the common tri-national surveillance network (Interreg, TIGER) enables the colonisation monitoring of the three invasive mosquito species already detected on both sides of borders: Ae. albopictus, Ae. japonicus and Ae. koreicus. Considering a cross-border area, integrating the European scale for vector monitoring and control is thus a major asset to the issue of arboviruses vectors.
