They are presented parasitic complexes of two species scale insects from oak: Parthenolecanium rufulum (Cockerell) (Fam. Coccidae) and Kermes roboris (Fourcroy) (Fam. Kermesidae). We analyzed at P. rufulum, 1798 specimens of parasites and they were identified the follow species: Blastothrix longipennis Howard, Metaphycus insidiosus Mercet, Coccophagus lycimnia Walker (primary parasites), Pachyneuron muscarum Linne and Marietta picta Andre (secondary parasites). Dominant was the species B. longipennis. At females the total parasitic percentages were between 29,6 şi 42,3%. The parasites reduced the prolificity of the females on average with 60,1%. In K. roboris, of the females, we obtained 949 parasite specimens and identified the species: Blastothrix erythrostetha Walker (Fam. Encyrtidae), Aprostocetus pachyneurus (Ratzeburg) (Fam. Eulophidae) and Diptera (larvae). Dominant was the species B. erythrostetha. In a females of K. roboris, B. erythrostetha deposited between one and 24 eggs. The total parasitic percentages were between 0 and 53,5%.. In this species case, although parasite, some females have managed to lay eggs. The parasites reduced the prolificity of the females on average with 36,2%.
