Abstract: | The Asian longhorned beetle, (Coleoptera, Cerambycidae, Anoplophora glabripennis (Motschulsky)), is endemic to China and Korea and an important invasive insect in North America and Europe. We analyzed mitochondrial
DNA sequence data of invasive populations of A. glabripennis in North America and Europe, and microsatellite allele frequency data of beetles from North America. We show that populations
in New York City and Long Island NY; New Jersey, Chicago, IL, and Toronto, Canada have limited genetic diversity compared
to populations in China. In addition, the data suggest that separate introduction events were responsible for many of the
populations in North America and for European populations in Austria, France, Germany and Italy. Populations on Long Island,
NY are suspected to have been initiated by the transport of cut wood from New York City. A. glabripennis beetles found in Jersey City, NJ appear to be derived from an expansion of the New York City, NY population, whereas beetles
found in Linden, NJ are an expansion from the Carteret, NJ population. Limited genetic diversity did not stop this invasive
insect from establishing damaging populations in North America. Founders of introduced A. glabripennis populations in North America and Europe are likely derived from populations in China that are themselves invasive, rendering
difficult the identification of source populations. Invasiveness in an insect’s natural range could be an important predictor
of potential pest status of introduced populations. |
