Published online by Cambridge University Press: 31 May 2012
Extract
The rose stem girdler (Agrilus communis rubicola Ab.), a pest of European origin, was first recorded on this continent in 1913. The earliest report of its presence in Ontario was made in 1931 in the Windsor area by Mr. C. S. Thompson, formerly of the Dominion Plant Inspection Service, who found it infesting roses on private grounds. The roses had been obtained in 1929 from a Michigan nursery which had imported them from Holland.
