Temperature Extremes May Undermine Biocontrol of Emerald Ash Borer
Sudden cold waves may be lethal to overwintering larvae of two parasitoid wasp species used for biological control of emerald ash borer, while the borer larvae appear to more easily weather the extreme cold.
White Fringetrees Likely to Withstand Attacks by Emerald Ash Borer
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.
Fungus Could Help Control Emerald Ash Borer
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.
A Promising New Parasitoid Drills Down on Emerald Ash Borers
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.
