Abstract

The species of Pteromalidae (Chalcidoidea) introduced to British Columbia, Canada, from Europe in 1949 as Trichomalus fasciatus (Thomson, 1878), Xenocrepis pura Mayr, 1904, and Habrocytus sp. for classical biological control of Ceutorhynchus obstrictus (Marsham, 1802) (Coleoptera: Curculionidae) are shown to be misidentifications of Trichomalus perfectus (Walker, 1835), Mesopolobus morys (Walker, 1848), and Stenomalina gracilis (Walker, 1834), respectively. Species reared subsequently from seedpods of Brassica spp. (Brassicaceae) in British Columbia and reported in the literature under the first three names are shown to be misidentifications of, respectively, Trichomalus lucidus (Walker, 1835), Mesopolobus moryoides Gibson, 2005, and one or both of Pteromalus puparum (L., 1758) and T. lucidus. There is no evidence that either T. perfectus or M. morys established in North America, but S. gracilis is newly recorded from southern British Columbia based on specimens reared from Brassicaceae seedpods in 2004 and 2005.

Résumé

Les espèces de Pteromalidae (Chalcidoidea) introduites d'Europe en Colombie-Britannique, Canada, en 1949 sous les noms de Trichomalus fasciatus (Thompson, 1878), de Xenocrepis pura Mayr, 1904 et d'Habrocytus sp. pour faire une lutte biologique classique à Ceutorhynchus obstrictus (Marsham, 1802) (Coleoptera : Curculionidae) ont été mal identifiées et appartiennent en fait respectivement aux taxons Trichomalus perfectus (Walker, 1835), Mesopolobus morys (Walker, 1848) et Stenomalina gracilis (Walker, 1834). Des espèces élevées subséquemment à partir de capsules de graines de Brassica spp. (Brassicaceae) en Colombie-Britannique et citées dans la littérature sous les trois premiers noms ci-haut ont aussi été mal identifiées et appartiennent respectivement à Trichomalus lucidus (Walker, 1835), à Mesopolobus moryoides Gibson, 2005 et à l'une ou les deux des espèces Pteromalus puparum (L., 1758) et T. lucidus. Il n'y a pas d'indication que T. perfectus ou que M. morys se soient établies en Amérique du Nord; cependant, la présence de S. gracilis est signalée pour la première fois dans le sud de la Colombie-Britannique, à l'étude de spécimens élevés sur des capsules de graines de Brassicaceae en 2004 et 2005.
