Abstract

Arasbaran forests are located in East Azarbaijan and account as one of the most important forests of north western of Iran. Due to the impacts Khazari, Ghafghazi and Mediteranean climates, this area has wide variety of biological societies. In reach plant coverage of Arasbaran forests Horn-bean and Oak trees (Quercus petraea and Q. macranthera) are dominant species respectively.
The Oak weevil, Balaninus glandium Marsh. is one of the most important key pests (about 40% damage) of Oak trees in Arasbaran forests. The pest feeding inside the Oak fruit, cause destruction of seeds. During the biological study of the pest in Arasbaran we found some of it's natural enemies. In the course of survey of the natural enemies of the pest, a larval parasitoid wasp of Ichneumonidae familly was found and later identified as Scambus planatus (Hartig). The wasp has identified by Dr. E.Diller in German Museum of natural history and is reported here for the first time from Iran. The parasitoid wasp overwinters as adult and has a single generation in Arasbaran area. The rate of parasitism was estimated between 0.53% to 10% (average 3.93%) on its host.
