  abstract = {{B}iological invasions have ecological impacts worldwide with potential massive economic costs. {A}mong other ecosystem services such as nitrogen cycle, carbon sequestration and primary production, invasive alien species are particularly known to impact pollination. {B}y predating honey bees ({A}pis mellifera), the invasive {Y}ellow-legged hornet ({V}espa velutina nigrithorax) increases the mortality risk of {E}uropean bee colonies; however, little is known about its economic costs. {W}e developed an analytic process combining large-scale field data, niche modelling techniques and agent-based models to spatially assess the ecological and economic impacts of the {Y}ellow-legged hornet on honey bees and beekeeping in {F}rance. {I}n particular, we estimated (i) the hornet-related risk of bee colony mortality, (ii) the economic cost of colony loss for beekeepers and (iii) the economic impact of livestock replacement compared to honey revenues at regional and national scales. {W}e estimated an overall density of 1.08 hornet nest/km2 in {F}rance, based on the field record of 1260 nests over a searched area of 28,348 km2. {H}owever, this predator density was heterogeneously spread out across the country as well as the distri-bution of managed honey bee colonies. {O}verall, this hornet-related risk of bee colony mortality could reach up to 29.2 % of the beekeepers' livestock at national scale each year in high predation scenario. {T}his national cost could reach as much as euro 30.8 million per year due to colony loss, which represents for beekeepers an economic impact of livestock replacement of 26.6 % of honey revenues. {O}ur results suggest non-negligible ecological and economic impacts of the invasive {Y}ellow-legged hornet on honey bees and beekeeping activities. {M}oreover, this study meets the urgent need for more numerous and accurate economic estimations, necessary to calculate the impact of biological invasions on biodiversity and human goods, with a view to enhance policies of biodiversity conservation.},
