The spring leafroller complex in organically managed apple orchards in the north of the Okanagan valley in British Columbia is predominantly composed of Archips rosanus (Linnaeus) and Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), unlike the predominantly C. rosaceana and Pandemis limitata (Robinson) (Lepidoptera: Tortricidae) complex in the south of the valley. Twenty-three parasitoid species, including three possible hyperparasitoids, were reared from leafrollers in the northern organic orchards from April through June in 2001 and 2002, of which 15 of the parasitoid species represent new parasitoid records for the leafroller complex in the Okanagan valley. The most commonly reared parasitoid in the northern organic orchards, Enytus eureka (Ashmead) (Hymenoptera: Ichneumonidae), is not common in southern orchards. Meteorus trachynotus Viereck, Microgaster epagoges Gahan and Apanteles polychrosidis Viereck (Hymenoptera: Braconidae) were also frequent parasitoids within the northern leafrolle...
