Gall wasps (Hymenoptera: Cynipidae) that is one of the successful groups in Hymenoptera are known for their ability to induce complex plant galls. The species Diplolepis fructuum (Rubsaamen) (Cynipidae) induce fruit galls on dog roses (Rosa spp.), and it is known to be the most important pest on dog roses in Turkey. In this study, D. fructuum galls were collected from Rosa canina L. in four provinces of Turkey during 2013-2014. In addition to 22 species formerly reported to be associated with rose gall wasps in Turkey, the present study found 3 parasitoid wasp species that are not regularly associated with Diplolepis galls, namely Pediobius bruchicida (Rondani) (Eulophidae), Cyrtoptyx lichtensteini (Masi) and Mesopolobus amaenus (Walker) (Pteromalidae). Cyrtoptyx lichtensteini is a new record for Turkey. Finally, a list of parasitoids associated with rose gall wasps in Turkey is presented. The gall-associated parasitoid wasps of Turkey, including Diplolepis, are discussed and compared with those of the Palaearctic region and Iran.
