The parasitoid complex of the Agromyzidae L. trifolii (Burgess), C. horticola (Goureau) and C. syngenesiae Hardy was investigated on glasshouse crop plants in Tuscany. L. trifolii is the most widespread and polyphagous leaf miner while C. syngenesiae shows a preference for the chrysanthemum. Nine Hymenoptera species were found: the Braconidae Dacnusa areolaris (Nees) and Dacnusa veronicae? Griffiths, endoparasitoids of C. horticola and syngenesiae, and the following Eulophidae: Chrysocharis sp., Chrysonotomyia formosa (Westwood) and Pediobius acantha (Wlk.), endophagous species; Cirrospilus vittatus Wlk., Diglyphus isaea (Wlk.), Hemiptarsenus dropion (Wlk.) and Pnigalio sp., ectophagous species. D. isaea is dominant every month in the year, followed by C. formosa and H. dropion. C. formosa and D. isaea were reared from all three species of Agromyzidae; C. vittatus and H. dropion from L. trifolii and C. horticola; P. acantha from two Chromatomyia; Chrysocharis sp. only from C. syngenesiae; Pnigalio sp. only from L. trifolii. C. vittatus is recorded for the first time as a parasitoid of L. trifolii. none
