Five species of gall-inducing Diplolepis are reported from Rosa spp. in Turkey - D. eglanteriae (Hartig), D. fructuum (Rübsaamen), D. mayri (Schlectendal), D. rosae (Linnaeus), and D. spinosissimae (Giraud). The most abundant gall is that induced by D. fructuum which is often considered a pest of the rose industry because it can completely destroy the hips. In some areas, up to 90% of the hips are infested by galls of D. fructuum. Diplolepis eglanteriae, D. mayri, D. spinosissimae, and D. rosae induce galls on the leaves, but are uncommon and not considered pests. The importance of Turkey as a midpoint between Europe and Asia in the distribution of roses and Diplolepis is discussed. The inducer responsible for hip galls in Turkey previously identified as D. mayri is reported here as D. fructuum.
