Four species of Asian parasitoid species have been released in the North America for emerald ash borer biological control. Although, some of these species attacked one or more native Agrilus during laboratory host-range testing, their risk to native fauna was predicted to not be significant. We conducted field studies where three Asian parasitoid species were established to determine if native Agrilus are being attacked by these species. Here we present preliminary results of this work.
