Observations on emerald ash borer (EAB), Agrilus planipennis Fairmaire, and its natural enemies were made at Cranberry, PA in 2007 and 2008. Several species of parasitic Hymenoptera were recovered from late instar EAB larvae and prepupae, including Balcha indica Mani & Kaul, a eupelmid previously recovered from A. planipennis in Michigan. Woodpecker predation was substantial at some sites.


Species 1: Coleoptera Buprestidae Agrilus planipennis (emerald ash borer)
Species 2: Hymenoptera Eupelmidae Balcha indica
