During the last two centuries, thousands of insect species have been moved (mostly unintentionally) outside of their native ranges. Some of these species were able to establish in new areas and in some cases with catastrophic ecological and economic impacts. Why have some world regions been invaded by more insect species than others?
The insects are a group that has been underrepresented in the field of invasion biology, despite their impacts on agricultural production (e.g. fruit flies), ecosystem disruptions (e.g. ants) and vectors of disease that affect human health (e.g. mosquitoes). Further, much of the theory of invasion biology has come from work focused on plant and vertebrate invasions.
