摘要
Diplolepis rosaefolii (Cockerell) induces a lenticular gall on the leaves of various roses across Canada. In Ontario and Quebec, D. rosaefolii is found only on Rosa acicularis Lindl., and its galls are inhabited by eight species of parasitoids, the most common being Chrysocharis pentheus (Walker), Orthopelma luteolator (Gravenhorst), and Eupelmus dryorhizoxeni Ashmead. Parasitoids and the inquiline Periclistus sp. make up 48-62% of gall inhabitants. Here we report a population : of D. rosaefolii on the hybrid rugosa shrub rose Therese Bugnet in a field of experimental roses in Quebec. Only two species of parasitoids and one specimen of Periclistus sp. were associated with these galls.
