Investigating the rearing of the grape leaf-roller Sparganothis pilleriana (Den. et Schiff.) from the larvae and pupae collected between 1998-2003 in two vineyards of southern Romania, 7 chalcidoids species were obtained as primary parasitoids: Brachymeria intermedia (Nees), Pteromalus sp., Cyclogastrella deplanata (Nees), Dibrachys cavus (Walker), Dibrachys sp., Colpoclypeus florus (Walker) and Elasmus viridiceps Thomson. These species realized a reduction in the populations of S. pilleriana by 6.58%. Of those, the greatest importance is held by Brachymeria intermedia as a primary pupal parasitoid (3.6%), and by Colpoclypeus florus as a primary larva parasitoid (1.6%). All of the host-parasitoid relationships are new for Romania. A case of multiple parasitism was recorded as well when a female of Elasmus viridiceps parasitized with a female of Colpoclypeus florus, a mature larva of S. pilleriana.
