In spite of widespread application of poisonous bait sprays against Dacus oleae in Crete, populations of its parasites sometimes show high densities. Most important are the chalcid ectoparasites Eupelmus urozonus and Pnigalio mediterraneus and the braconid Opius concolor . Several efforts for biological control of D. oleae with O. concolor have been made in Greece. The most promising were inundative releases against the spring generation of D. oleae as well as releases within foci of D. oleae in summer. Introduced exotic parasitoids ( Biosteres longicaudatus, Dirhinus giffardii and B. oophilus ) failed to establish.
