In a recent study, the wasp Spathius galinae successfully established wild populations and outperformed other parasitoids in attacking invasive emerald ash borers in three northeastern states in the U.S. Researchers say it could become a useful biological control agent to protect native ash trees.
In Pennsylvania, where emerald ash borer has been present since 2007, municipalities have found successful ash-management plans under guidance of the state's Department of Conservation and Natural Resources, and they offer a model for other regions to follow.
