PARASITISM OF OVERWINTERING PUPARIA OF THE CABBAGE MAGGOT, DELIA RADICUM (L.) (DIPTERA: ANTHOMYIIDAE), IN RELATION TO HOST DENSITY AND WEATHER FACTORS
Abstract Puparia of Delia radicum collected in late autumn at Winnipeg and Portage la Prairie (Manitoba), St-Jean-sur-Richelieu (Quebec), London (Ontario), and St. John’s (Newfoundland) were parasitized mainly by Aleochara bilineata (Gyllenhal) (Coleoptera: Staphylinidae) and Trybliographa rapae (We...
