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 (Rubsaamen, 1895) (Hymenoptera: Cynipidae) on host plants from the genus Rosa were collected. Thirteen species from six families were reared. Among them, Eurytoma caninae Lotfalizadeh & 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.
