The Parasitoid Complex Associated with Larinus sibiricus Gyllenhal, 1835 (Coleoptera: Curculionidae) in Bulgaria.

The weevil Larinus sibiricus Gyllenhal and a rich complex of associated hymenopteran parasitoids were reared from flower heads of Xeranthemum annuum L. (Asteraceae) in Bulgaria. As a result, the following taxa were established: Bracon urinator (Fabricius) (Braconidae), Exeristes roborator (Fabricius) (Ichneumonidae), Cyrtoptyx sp., Norbanus cerasiops (Masi), Pteromalus vibulenus (Walker), Stenoselma nigrum Delucchi (Pteromalidae), Exopristus trigonomerus (Masi) (Torymidae), Leptomastix ephyra Noyes & Hayat (Encyrtidae), Aprostocetus venustus (Gahan), Baryscapus sp. near carthami Graham (Eulophidae), Eupelmus microzonus Förster (Eupelmidae) and Eurytoma curculionum Mayr (Eurytomidae). Three of them (E. curculionum, L. ephyra and N. cerasiops) are recorded for the first time from Bulgaria and L. ephyra is a newly recorded species for the Balkan Peninsula and Europe. New associations with L. sibiricus and X. annuum were established for all reared parasitoids except B. urinator. [ABSTRACT FROM AUTHOR]
