Chalcidoid parasitoids of Chromatomyia horticola (Gour.) (Dip. Agromyzidae) in Sivas Province, Turkey

Abstract

Chromatomyia horticola (Goureau, 1851) (Diptera Agromyzidae) is a polyphagous species and very common worldwide. In this study, parasitoids of Chromatomyia horticola were investigated on various plants during 2003 in the Sivas province. Infested leaves were sampled weekly and kept in the laboratory to observe and count emerging leafminers and parasitoid adults. Eight parasitoid species were reared belonging to Eulophidae and Pteromalidae (Chalcidoidea). Diglyphus iseae (Walker), Pediobius metallicus (Nees) and Diglyphus pachyneurus Graham represent the predominant parasitoid species. Among the parasitoids reared, Aprostocetus flavifrons (Walker), Merismus sp., and Chrysocharis crassiscapus (Thomson) have been newly recorded in Turkey and Aprostocetus flavifrons, Chrysocharis crassiscapus, Diglyphus pachyneurus Graham, and Merismus sp. were recorded for the first time from C. horticola.
