Abstract
ICE abstract: The close evolutionary relationship between weevils (superfamily Curculionoidea) and their host plants make them very important economically, both as pests of stored grain, trees, crops and shrubs, as well as biological control agents used against invasive weeds. Based on a recent checklist, Canada is home to 960 species of weevils. Of these, approximately 125 species (13%) are adventive (i.e., not native to Canada, having arrived either unintentionally or through deliberate human action). Working towards a synthesis of the biology, host records and economic impact of each adventive species, we review their current distribution, native range and dates of introduction into Canada. General pathways of entry into Canada will also be discussed.
