Investigation on parasitoids of bark beetles with new host record (Taphrorychus lenkoranus Reitter, 1913 (Curculionidae: Scolytinae)) from Northern forests of Iran

The present study was carried out to identify parasitoids of bark beetles in the forests of northern Iran, from 2013–2015 (May–August). Four hymenopterans species belonging to 3 families (Eulophidae, Pteromalidae and Braconidae) were identified as Ecphylus silesiacus (Ratzeburg, 1848), Cheiropachus quadrum (Fabricius, 1787), Rhaphitelus maculatus Walker, 1834 and Entedon ergias (Ratzeburg, 1844). Among the identified bark beetles species, T. lenkoranus Reitter, 1913 was recorded as a new host of E. silesiacus for the first time in the world
