Abstract: The state-of-the-art in knowledge on aphid parasitoids (Hymenoptera, Aphidiinae) of the fauna of Ukraine, is provided. The perspectives of involvement of these wasps in biological control and integrated pest management in Ukraine, are discussed. The established and prospective biocontrol agents of major aphid pests of main greenhouse crops in Ukraine, are reviewed. Aphidius ervi, A. matricariae, Binodoxys angelicae, Diaeretiella rapae, Lysiphlebus confusus, L. fabarum and Praon volucre are the most common among 19 aphidiine species recorded as associates of greenhouse pest aphids in Ukraine. It is emphasized that the proper selection of suitable biocontrol candidate should be grounded on correct identification, data of fecundity, parasitization rate, cost-efficiency of production. The implementation of such biocontrol programs strongly depends on a success of co-operation between academics and the stakeholders from organic production sector.
