Abstract

Eighteen parasitoid species were found associated with obliquebanded leafroller, Choristoneura rosaceana (Harris), and three-lined leafroller, Pandemis limitata Robinson, from 1982 to 1984, on apple and other host plants in the southern interior of British Columbia. The leafroller parasitoids included a Glypta Gravenhorst species (Hymenoptera: Ichneumonidae), Diadegma eureka (Ashmead) and Diadegma interruptum pterophorae (Ashmead) (Hymenoptera: Ichneumonidae), and Hemisturmia tortricis (Coquillett) (Diptera: Tachinidae). The two leafroller species were found on 18 wild host plants from 10 plant families.

Résumé

Dix-huit espèces de parasitoïdes associés à la Tordeuse à bandes obliques, Choristoneurea rosaceana (Harris) et à l’Enrouleuse trilignée, Pandemis limitata Robinson (Tortricidae) ont été trouvées dans des pommiers et d’autres plantes, de 1982 à 1984, à l’intérieur des terres, dans le sud de la Colombie-Britannique. Parmi les parasitoïdes, il y avait une espèce de Glypta Gravenhorst (Hymenoptera : Ichneumonidae), Diadegma eureka (Ashmead) et Diadegma interruptum pterophorae (Ashmead) (Hymenoptera : Ichneumonidae) et Hemisturmia tortricis (Coquillett) (Diptera : Tachinidae). Les deux espèces de Tortricidae ont été trouvées sur 18 plantes-hôtes appartenant à 10 familles.
