none no species Eleven hymenopterous species: two braconids, seven eulophids and two pteromalids parasitized the larvae of Phytomyza horticola Goureau. The activity of the parasites began at the end of April and evidently increased during May. The female of the parasites fed and parasitized mostly on the second and third larval instars of P. horticola. Diglyphus iseae Walker and Cirrospilus vittatus Walker were dominant larval parasites. Chrysocharis pentheus Walker and Pediohius acantha Walker were main pupal parasites. Phytomyza horticola (Agromyzidae): [Host]. Chalcidoidea (Terebrantia): [Parasite]. Braconidae (Ichneumonoidea): [Parasite].
