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.
An entomologist examining wasp specimens in fossilized amber from the Eocene (34–55 million years ago) has identified them as a new species, Brachyelatus marthae, and the first fossil specimens from the chalcid wasp subfamily Chrysolampinae.
In honor of Halloween, Entomology Today takes a look at zombie ants, cannibalistic termites, and other spooky insect science.
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.
