摘要: The complex of parasitoids the species Sparganothis pilleriana (Den. & Schiff.) was studied in two viticultural complexes South-Western Romania period 2000-2003. with most substantial performances Brachymeria tibialis (Walker, 1834), solitary pupal parasitoid, a total percentage parasitation within 3.59% and 12.14% only for pupae. maximum percentages parasitation, depending on place time were up to 40%. development laboratory larva pupa lasted 24 days. Males flew first, longevity females 2-12 weeks sex-ratio 0.64%. B. intermedia obtained as secondary parasitoid from Diadegma sp., relationship is new science. At same time, Catolaccus ater Ratz. pupae intermedia, being 7.14% host / new.
