Abstract

Between 2010 and 2012, approximately 6,300 Spathius agrili Yang (Hymenoptera: Braconidae) and 9,500 Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) parasitoids were released for biological control of the invasive emerald ash borer, Agrilus planipennis Fairmaire, at Cacapon State Park and the Cool Front Development in Morgan County, West Virginia. The invasive beetle was first detected there in 2009, and extensive ash mortality is currently occurring. We conducted parasitoid recovery surveys in 2013 but did not recover either of the released parasitoid species. However, we did rear Balcha indica Mani and Kaul (Hymenoptera: Eupelmidae), which is native to Asia and is a documented parasitoid of A. planipennis, from bolts infested with A. planipennis. This is the first documented record of B. indica for West Virginia.
