Parasitoids (Hymenoptera, Ichneumonidae) occurring in the Botanical Garden of Adam Mickiewicz University in Poznan.

摘要

The study was conducted in 2004-2006 in the Botanical Garden of Adam Mickiewicz University in Poznan. The quality and quantity structure of parasitoids belonging to selected Ichneumonidae subfamilies were defined. The method used was catching imagines into yellow Moericke's traps. 38 ichneumonid species belonging to 3 subfamilies were found. Pimplinae was the most numerous subfamily including 34 species. The other subfamilies like Diacritinae, Poemeniinae and Rhyssinae were represented by single species. The dominantig species in Pimplinae subfamily were: Pimpla contemplator (Muell.) (D=14.8%), Pimpla turionellae (L.) (D=13.4%), Itoplectis maculator (F.) (D=11.4%) and Zatypota gracilis (Holmgr.) (D=5.9%). Among ichnumonid caught, 25 species could reduce abundance of phytophages occurring in the Botanical Garden.
