Though found to be a secondary host of invasive emerald ash borers in North America in 2014, white fringetrees are more likely than ash trees to survive infestation by the beetles, according to a new study by researchers at Wright State University.
A recent study shows that male emerald ash borers infected with a deadly fungus readily transmit the fungus when mating, opening doors for future biological control efforts.
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.
