Abstract

The European sunflower moth [Homoeosoma nebulellum (Denis&Schiffermüller)] (Lepidoptera: Pyralidae) is one of the most important sunflower pest in Turkey. Concerning the parasitoids of this pest, the only one study was conducted in Turkey. The aim of this study is the identification of the parasitoids of the European sunflower moth. Bracon hebetor (Say.), B. trucidator (Marshall), B. pectoralis (Wesmael) (Hymenoptera: Braconidae) and Exeristes roborator F. (Hymenoptera: Ichneumonidae) were found as natural enemies. Bracon pectoralis was determined for the first time on the European sunflower moth in the world. Moreover, it was found that B. hebetor was more common among the other parasites and the rate of parasitism was high. Parasitism rate was estimated 9-30% and 0-6.6% in 2013 and 2014, respectively.
