Human-mediated movement is a major way in which forest pests get from one place to another. Many pests that live in or on wood can be unknowingly moved in firewood. A new review in the Journal of Economic Entomology looks at what we know about forest pest movement in firewood, and what we can do about it.
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.
