Extract

During a study on the parasitoids of the imported cabbageworm, Artogeia rapae (L.) (Lepidoptera: Pieridae), undertaken in 1993 and 1994, we recovered Cotesia rubecula (Marshall) (Hymenoptera: Braconidae) for the first time in Quebec, Canada. Samples were taken from pesticide-free plots of cabbage, broccoli, and Brussels sprouts located at Ste-Clotilde (45°09′N, 73°41′W) and L'Acadie, Quebec (45°18′N, 73°21′W), as described by Godin and Boivin (1998). In addition, survival of diapausing C. rubecula was evaluated after a 5-month incubation at 4°C (Godin 1997). Both A. rapae and C. rubecula are introduced species and originate most likely from Europe (Richards 1940). Artogeia rapae was discovered in 1860 in Quebec (Harcourt 1963), and C. rubecula was first reported in 1963 in British Columbia (Wilkinson 1966).
