none Entered The agromyzid leaf miners, Liriomyza trifolii (Burgess) and L. bryoniae (Kaltenbch) (Diptera: Agromyzidae) were found as major pests attacking faba bean (Vicia faba) in Alexandria, Egypt. A survey of their parasitoid species was carried out in 2012/13 and 2013/14 faba bean growing seasons. Parasitoid adults emerged from infested samples with the leaf miners were collected. Seven hymenopterous parasitoid species, belong to the families Braconidae and Eulophidae, were recorded; two braconids; Pseudopzomochus masii Nixon and Opius basalis (Fischer) and five eulophids; Diglyphus isaea (Walker), Chrysocharis pentheus (Kamijo), Halticoptera circulus (Walker), Halticoptera sp. and Zagrammosoma sp. Among the parasitoids surveyed, P. masii was recorded for the first time from Liriomyza spp. in Egypt; its sex ratio was female biased in all collected samples. D. isaea was the most predominant parasitoid species found, accounting 68.3 and 41.4% of the total parasitoids emerged in 2012/13 and 2013/14 seasons, respectively. It was active throughout the growing season and increased in number as the leaf miners' population increased. P. masii came next after D. isaea, particularly in the second season. Natural suppression of Liriomyza spp. by parasitoids seemed to be important for maintaining Liriomyza populations below damaging levels. 2014
