The hornet Vespa velutina is native to Asia, but has invaded a number of countries far afield from its origins. It was introduced into the southwest of France in 2004 or slightly earlier, and more recently spread to the neighbouring countries. Adapting well to the climate of the majority of French regions, it continues its expansion. At this rate, it is expected to arrive in Switzerland in the coming years. Although no figure has been put on the damage caused by the Asian hornet to the beekeeping sector, its impact is assumed to be serious, at least locally once the hornet has become established.
