Abstract

Surveys were conducted to determine the parasitoid communities associated with the cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham), an important invasive pest of canola in Ontario and Quebec, Canada. More than 18 species of Chalcidoidea (Hymenoptera) were associated with this pest through mass rearings from canola siliques. In southwestern Ontario, the most abundant species were a species of Chlorocytus Graham (23.6%–48.6%), Lyrcus perdubius (Girault) (0%–53%), L. maculatus (Gahan) (2.8%–14.7%), and species of Pteromalus Swederus (0.6%–23.1%) (Pteromalidae). In contrast, the most abundant species in Quebec were Trichomalus lucidus (Walker) (Pteromalidae) (33.3%–56.4%), unidentified Eulophidae (2.1%–39.1%), Mesopolobus gemellus Baur and Muller (Pteromalidae) (1.3%–21.4%), and Necremnus tidius (Walker) (Eulophidae) (11.5%–19.3%). In the Ottawa, Ontario, area, parasitoids were first recovered in 2008, and Trichomalus perfectus (Walker) (Pteromalidae), M. gemellus, and species of Pteromalus were most prevalent. Mesopolobus gemellus and T. perfectus are reported in North America for the first time. Although existing communities appear to provide substantial parasitism (e.g., 6.3%–26.3% in 2006), species composition varies among years and differs from that in other regions in North America. Thus, parasitism levels and parasitoid communities of the cabbage seedpod weevil should be monitored to assess whether these will increase or there is a need to introduce more host-specific species from Europe that could provide greater mortality.

Résumé

On a entrepris cette étude dans le but d'identifier la communauté de parasitoïdes associée au charançon de la graine du chou, Ceutorhynchus obstrictus (Marsham), important ravageur envahissant du colza en Ontario et au Québec, Canada. On a recensé plus de 18 espèces de la superfamille des Chalcidoidea (Hymenoptera) en faisant l—élevage de masse à partir de siliques du colza. Les espèces les plus abondantes dans le sud-ouest de l'Ontario étaient une espèce de Chlorocytus Graham (23.6 %–48.6 %), Lyrcus perdubius (Girault) (0 %–53 %), L. maculatus (Gahan) (2.8 %–14.7 %), et des espèces du genre Pteromalus Swederus (0.6 %–23.1 %) (Pteromalidae). Par contre, les espèces les plus abondantes au Québec étaient Trichomalus lucidus (Walker) (Pteromalidae) (33.3 %–56.4 %), une espèce de la famille des Eulophidae non identifiée (2.1 %–39.1 %), Mesopolobus gemellus Baur et Muller (Pteromalidae) (1.3 %–21.4 %) et Necremnus tidius (Walker) (Eulophidae) (11.5 %–19.3 %). Trichomalus perfectus (Walker) (Pteromalidae), M. gemellus, et une espèce de Pteromalus sont les parasitoïdes qui ont été recensés en plus grand nombre en 2008 dans la région d'Ottawa, Ontario. On rapporte pour la première fois la présence de Mesopolobus gemellus et T. perfectus en Amérique du Nord. Bien que le taux de parasitisme soit significatif (par exemple entre 6.3 % et 26.3 % en 2006), la composition de la communauté de parasitoïdes diffère d'année en année et par rapport à des communautés d'autres régions de l'Amérique du Nord. En conséquence, on recommande d'effectuer un suivi des taux de parasitisme et des communautés de parasitoïdes s'attaquant au charançon de la graine du chou afin de démontrer si il est nécessaire d'introduire d'autres espèces d'Europe présentant une plus grande spécificité à l—égard de l'hôte pour augmenter les taux de mortalité.
