Hypera rumicis (Linnaeus, 1758), new to Quebec

Species identification confirmed by Hiraku Yoshitake, 2014

Note.

Since its accidental introduction and first detection in the United States in 1879 (Chamberlin, 1933), this Palaearctic species has expanded its range considerably in North America. Surveys conducted from 1997 to 1999 in two Quebec vineyards failed to detect its presence ( Bouchard et al. 2005), but its capture by C. Tessier in 2003 indicates that it was already present in the province more than a decade ago. Hypera rumicis is associated with various Polygonum L. spp. and Rumex spp. ( Polygonaceae ), especially the invasive curled dock, Rumex crispus L., also introduced from Europe. Its potential as a biological control agent against this weed was recently assessed ( DeGregorio et al. 1992; Piesik 2006). This species was previously known in Canada from Alberta, Saskatchewan, Manitoba, and Ontario ( Bousquet et al. 2013).
