Field studies were carried out in April, October, and November 2013 and March and October 2014 in Tokat Province of Turkey. Gall specimens of Diplolepis fructuum (Rübsaamen, 1895) (Hymenoptera: Cynipidae) on host plants from the genus Rosa were collected. Thirteen species from six families were reared. Among them, Eurytoma caninae Lotfalizadeh and Delvare, 2007 and Aximopsis collina (Zerova, 1984) are new records for Turkey. The most common parasitoids are Eupelmus urozonus Dalman, 1820 and Stepanovia eurytomae (Nees, 1834), respectively.
