not in Young During 2007, we investigated the parasitoid complex which controlling Brevicoryne brassicae L. populations from some cabbage cultures on Black Seaside areas. There were identified 17 parasitoids species, from 10 genera, which are grouped into 5 families. Also, we tried to explain trophic relationships between parasitoid species and we made a synecologic analysis on parasitoid species front the perspective of the role of each species in biological control of Brevicoryne brassicae L. populations. Brevicoryne brassicae (Aphidoidea): Host; Pteromalidae (Chalcidoidea): Parasite; Syrphophagus aphidivorus (Encyrtidae): Parasite; Charipidae (Cynipidae): Parasite; Aphidiidae (Ichneumonoidea): Parasite; Megaspilidae (Ceraphronidae): Parasite.
