Abstract

Four lepidopterous and sawfly species were collected from Lonicera (honeysuckle) in the Ottawa area and reared for hymenopterous parasites. The following new species are described here, with new host records: Triclistus xylostellae n. sp. (Ichneumonidae, Metopiinae) from Plutella xylostella (Linnaeus) (Lepidoptera, Plutellidae), Copidosoma glandiferellae n. sp. (Chalcidoidea, Encyrtidae) from Deltophora glandiferella (Zeller) (Lepidoptera, Gelechiidae). The following are new host records: Mesochorus vittator (Zetterstedt) (Ichneumonidae, Mesochorinae) hyperparasitic in Olesicampe lophyri (Riley) (Ichneumonidae, Campopleginae) from Zaraea americana Cresson (Hymenoptera, Cimbicidae), Oncophanes americanus (Weed) (Braconidae) from D. glandiferella. The following are parasitic species with lepidopterous hosts already recorded: Apophua simplicipes (Cresson) (Ichneumonidae, Banchinae) and Macrocentrus iridescens French (Braconidae), both on Choristoneura rosaceana (Harris) (Lepidoptera, Tortricidae). The cephalic structures of the final-instar larvae of the following species are described: T. xylostellae n. sp., M. vittator, and A. simplicipes.

Résumé

Quatre espèces de Lépidoptères et de tenthrèdes ont été prélevées de Lonicera (chèvrefeuille) dans la région d'Ottawa et élevées pour servir d'hôtes à des Hyménoptères parasites. Les nouvelles espèces avec leur éventail de nouveaux hôtes sont décrites : Triclistus xylostellae n.s. (Ichneumonidae, Métopiinés) de Plutella xylostella (L.) (Lépidoptères, Plutellidés), Copidosoma glandiferellae n.s. (Chalcidoidés, Encyrtidés) de Deltophora glandiferella (Zeller) (Lépidoptères, Géléchiidés). Les nouvelles espèces d'hôtes sont : Mesochorus vittator (Zetterstedt) (Ichneumonidés, Mésochorinés) hypperparasite de Olesicampe lophyri (Riley) (Ichneumonidés, Campopléginés) de Zaraea americana Cresson (Hyménoptères, Cimbicidés), Oncophanes americanus (Weed) (Braconidés) de D. glandiferella. Des espèces parasites d'hôtes Lépidoptères déjà recensés sont : Apophua simplicipes (Cresson) (Ichneumonidés, Banchinés) et Macrocentrus iridescens French (Braconidés), toutes les deux parasites de Choristoneura rosaceana (Harris) (Lépidoptères, Tortricidés). Les structures céphaliques du dernier stade larvaire des espèces suivantes sont décrites : T. xylostellae n.s., M. vittator et A. simplicipes.
