The Palearctic species Bembidion femoratum and Amara communis (Coleoptera: Carabidae): new records and notes on modes of introduction to North America
نویسنده
چکیده
The Palearctic species Amara communis (Panzer) and Bembidion femoratum Sturm were both first reported from North America in 1992. Since that time a sizeable number of additional specimens of both species have been found, which substantially expands their known range on the continent. These records are summarized herein. The possible modes of introduction of both species are discussed within the context of other introduced insects, particularly those first found in Atlantic Canada. In the case of A. communis, the many coastal localities where it occurs would seem to indicate that it was introduced in association with transatlantic marine traffic, possibly the shipment of dry ballast. In the case of B. femoratum, the mode of introduction is less clear. Possible associations with nursery stock, dry ballast, and the movement of aircraft are all discussed. Résumé—Les espèces paléarctiques Amara communis (Panzer) et Bembidion femoratum Sturm ont toutes deux été signalées pour la première fois en Amérique du Nord en 1992. Depuis lors, un nombre important de spécimens supplémentaires des deux espèces ont été récoltés, ce qui augmente considérablement leur aire de répartition connue sur le continent. On en trouvera ici la compilation succincte. La discussion porte sur les voies d’introduction de ces deux espèces dans le contexte de l’établissement d’autres insectes exotiques, particulièrement ceux signalés pour la première fois dans la région altantique du Canada. Dans le cas d’A. communis, les nombreuses localités côtières où elle se retrouve sembleraient indiquer une introduction reliée au transport maritime transatlantique, probablement dans les matériaux secs utilisés pour le ballastage. Le mode d’introduction de B. femoratum est moins clair; des associations possibles avec les stocks de pépinières, les matériaux secs de ballastage et les déplacements des aéronefs sont considérées.
