Distribution of an Invasive Weevil, Pseudocneorhinus bifasciatus Roelofs, in the Southeastern United States

Abstract

The twobanded Japanese weevil, Pseudocneorhinus bifasciatus Roelofs, first found in North America near Philadelphia, PA, in 1914, is better known in the northeastern United States than in the Southeast. Based on examination of specimens in 11 museums, fieldwork, and review of the literature, we document the presence of this pest of ornamental plants in Alabama (3 counties), Georgia (12), North Carolina (16), and South Carolina (19). The southeastern distribution is mapped, and locality and date are provided for the first collection in each state: North Carolina, 1955; Georgia, 1956; South Carolina, 1966; and Alabama, 1970.
