Rice ecosystems are rich in natural enemies, particularly parasitoids. The current investigation was carried out at the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh during 2014 and 2015 rice seasons. The objective was to survey hymenopterous parasitoids occurring in rice fields. Specimens were collected from rice nursery and paddy field by sweep net, pitfall trap, water pan trap, light trap and D-vac machine. Thirty-nine species of parasitoids were recorded, belonging to fifteen families. Sixteen parasitoid species, in four families are recorded herein for the first time in the Egyptian rice fields. The most abundant species were Dipriidae (3 species) and Gronotoma sp. (Figitidae). While, Opius hediqusti Fish., Aphenogomus sp., Camptoptera sp. Callitula sp. Trissolcus sp., Telenomus sp., and Oligosita sp. The rest of 23 species were less numbers during the two seasons.
