Abstract Cabbage root maggot, Delia radicum (Linnaeus) (Diptera: Anthomyiidae), has been an economically serious pest, damaging a wide range of Brassica crops, across Canada since the late 1800s. A robust body of research literature exists, encompassing a range of control options that have been explored across commodities within Canada. Despite this body of work, pesticides remain the most commonly used option for control of D. radicum . Insecticides registered for use against D. radicum in Canada are facing increasing restrictions or deregulation, making D. radicum more difficult to manage. This review provides an overview of the research conducted in Canada up to 2022 and discusses various management approaches that need to be explored to lessen our current reliance upon insecticides for D. radicum control.
