The Impact

Reconstructing the geographic origins of invasive species is critical for establishing effective management strategies. Frequently, molecular investigations are undertaken when the source population is not known, however; these analyses are constrained both by the amount of diversity present in the native region and by changes in the genetic background of the invading population following bottlenecks and/or hybridization events. Here we explore the geographical origins of the invasive winter moth (Operopthera brumata L.) that has caused widespread defoliation to forests, orchards, and crops in four discrete regions: Nova Scotia, British Columbia, Oregon, and the northeastern United States. It is not known whether these represent independent introductions to North America, or “stepping stone” spread among regions. Using a combination of Bayesian assignment and approximate Bayesian computation methods, we analyzed a population genetic dataset of 24 polymorphic microsatellite loci. We estimate that winter moth was introduced to North America on at least four occasions, with the Nova Scotian and British Columbian populations likely being introduced from France and Sweden, respectively; the Oregonian population likely being introduced from either the British Isles or northern Fennoscandia; and the population in the northeastern United States likely being introduced from somewhere in Central Europe. To our surprise, we found that hybridization has not played a large role in the establishment of winter moth populations even though previous reports have documented widespread hybridization between winter moth and a native congener. We discuss the impact of genetic bottlenecks on analyses meant to determine region of origin.

The European pine shoot moth, Rhyacionia buoliana (Schiff.), was first discovered in North America on Long Island, New York, in 1914 (Busck, 1914). Since that time it has spread throughout most of the northeastern United States, becoming one of the most important insect pests of pine plantations. In Ontario, it was first discovered in the Toronto area (McLaine, 1926) and since that time has dispersed throughout southern Ontario, appearing regvlarly south of a line from the southern end of Gcorgian Bay to a point just east of Lake Ontario (Fig. 1). Isolated occurrences of the shoot moth have been reported north of this line but these have been short-lived on small plantation trees, or have persisted in cities and towns on ornamentals protected by snow cover during the winter. The continuous distribution of the insect has remained relatively static since 1951, and it appears that the northern limit of its range in Ontario has been reached.
