Abstract
The geographical exchange of non native insects can be highly asymmetrical, with some world regions ‘exporting’ or ‘importing’ more species than others. Several hypotheses have been proposed to explain such asymmetries, including differences in propagule pressure, environmental features in recipient regions, or biological traits of invaders. We tested aspects of these hypotheses in the context of the exchange of non native insects between North America, Europe, and Australasia. Europe was the dominant exporter of non native insect species between the three regions, with most of this asymmetry arising prior to 1950. The European dominance could not be explained by differences in import value, source species pool sizes, or native plant richness in the recipient regions. We identified that the introduction of non native plants, driven in part by European colonization, best explains the asymmetrical exchange of non native insects between our focal regions.
