Alysiinae (Hymenoptera: Braconidae) parasitoids of the pea leaf miner, Chromatomyia horticola (Goureau, 1851) (Diptera: Agromyzidae) in Kermanshah, Iran

Chromatomyia horticola (Goureau) (Diptera: Agromyzidae) is a highly polyphagous leaf miner that cause severe damage to different crops. Sampling on the Alysiinae (Braconidae) parasitoids of C. horticola was performed at various locations of Kermanshah province during 2009–2010. Infested leaves of host plants bearing the larvae and puparia of C. horticola were collected and placed inside the plastic rearing boxes and transferred to laboratory. The samples were preserved for 2–4 weeks, until the emergence of parasitoids. Three species of Alysiinae parasitoids were reared and identified in the association with C. horticola in Kermanshah including, Chorebus (Stiphrocera) aphantus (Marshall, 1986), Chorebus (Stiphrocera) uliginosus (Haliday, 1839) and Dacnusa (Aphantus) hospita (Foerster, 1862). All three species have been recorded for the first time as parasitoids of C. horticola. In addition, C. aphantus is newly recorded for the fauna of Iran. An identification key to the parasitoid species is given.
