Abstract

Three buprestid species, Actenodes acornis (Say, 1836), Dicerca asperata (Laporte et Gory, 1837), and Dicerca lepida LeConte, 1857, are newly recorded from Canada on the basis of a collection of 57 buprestid specimens taken from females of the crabronid wasp Cerceris fumipennis Say, 1837 in Rondeau Provincial Park, Chatham-Kent region, Ontario, in July 2004. Nine additional buprestid species were taken from wasps that were intercepted as they approached their nests, demonstrating the effectiveness of C. fumipennis nest sites as sampling stations for buprestid beetles. We suggest that this sampling method could be applied to efficiently monitor the spread of the emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae) in eastern North America.

Résumé

Trois espèces de buprestidés, Actenodes acornis (Say, 1836), Dicerca asperata (Laporte et Gory, 1837) et Dicerca lepida LeConte, 1857, sont signalées pour la première fois au Canada et elles proviennent d'une récolte de 57 spécimens de buprestidés récupérés de guêpes femelles, Cerceris fumipennis Say, 1837, de la famille des crabronidés, dans le parc provincial Rondeau, région de Chatham-Kent, Ontario, en juillet 2004. Neuf autres espèces de buprestidés ont été récupérées des guêpes interceptées alors qu'elles s'approchaient de leurs nids, ce qui montre l'intérêt des nids de C. fumipennis comme sites d'échantillonnage des coléoptères buprestidés. Nous croyons que cette méthode d'échantillonnage pourrait être utilisée pour suivre efficacement la dissémination de l'agrile du frêne, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), dans l'est de l'Amérique du Nord.
