An internal discussion of the positive and negative potential of non-native weevils in North America. This talk was particularly focused on weevils affecting sweet pepper production, including greenhouse growers in southern Ontario.
Abstract
Origin and establishment of non-native weevils in Canada, with a focus on Solanaceae Patrice Bouchard and Hume Douglas 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. Approximately 125 species (13% of the Canadian
fauna) 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, establishment and economic impact of each adventive species, we review their current distribution, native range and dates of introduction into Canada. Adventive weevils associated with Solanaceae will be highlighted.
