Emerald Ash Borer University has delivered critical knowledge about EAB and other invasive forest pests via webinar for more than a decade, and lessons learned from that experience can help improve other entomological extension and outreach efforts, as more of them adopt online formats in a post-pandemic world.
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.
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.
