Abstract
Eight Hymenopteran parasitoids: Itoplectis alternans (Grav.), Itoplectis maculator (F.), Pimpla spuria Grav., Diadegma apostata (Grav.), D. longicaudata Horst., D. tenuipes (Thoms.), D. holopyga (Thoms.) and Dibrachys cavus (Walk.), and one hyperparasitoid Gelis areator (Panz.) have been reared from the larvae and pupae of the grape moth Lobesia botrana (Denis et Schiffermüller), collected between 1996 and 2003 in two wineyards of southern Romania. Nine host-parasitoid relationships have been recorded, from which seven are new for Romania and the other two new to science. The role played by these parasitoids in the regulation of the host populations is 12.3%. Diadegma longicaudata Horst. is the most important member of this parasitoid complex with a parasitizing ratio of 7.75%. The parasitism of hibernating stages is more important than the summer ones, both in percentage (24.2/8.94%), and in species diversity (6/1). The small number of species and the low values of aestival and hibernal parasitizing are the effect of intensive chemical treatments in these vineyards.
