Abstract

A number of root maggot fly species from the large genus Delia Robineau-Desvoidy (Diptera: Anthomyiidae) are important pests of cultivated crucifers and many other field and vegetable crops. The present work provides identification keys in English and French to the adults, third instar larvae, puparia, and eggs of all pests of cultivated crucifers and other vegetable crops in Canada, namely Delia antiqua (Meigen), D. floralis (Fallén), D. florilega (Zetterstedt), D. planipalpis (Stein), D. platura (Meigen) and D. radicum (Linnaeus). DNA barcodes are provided for all species except D. planipalpis and new data on larval host associations in southern Québec are presented.
