Olive Tree is Second Non-Ash Species Found Vulnerable to Emerald Ash Borer

EAB larvae in olive stem

Last fall, researchers at Wright State University announced they had found that emerald ash borer can develop from larvae to adulthood on a species of olive tree. Today, that study is published online in the Journal of Economic Entomology. Their detailed report shows that 45 percent of the emerald ash borer (Agrilus planipennis) eggs that […]

A New Parasitoid Wasp from Russia May Help the Fight Against Emerald Ash Borer

By Ed Ricciuti Scientists working on environmentally friendly ways to combat insect pests continually quest for biological control’s version of a better mousetrap: natural enemies of a harmful species that outperform those already employed against it. In the case of invasive pests, the hunt may take scientists far afield, even to remote corners of the […]

Here’s How to Inspect Your Trees for Emerald Ash Borer

By Anand Persad, PhD Urban treescapes are under attack. Seven billion ash trees, the dominant species of urban American canopies, are at risk of being destroyed by the invasive emerald ash borer (EAB) if not treated. Since its first detection in Michigan in 2002, EAB has spread to 25 states and killed more than 50 […]

Emerald Ash Borer Infestation of White Fringetree Found to be Widespread

The emerald ash borer (Agrilus planipennis) is an invasive pest that is decimating ash trees across the United States and Canada. By 2019, it’s estimated that the beetle will have caused economic damage to the tune of $10 billion. While originally thought to be a pest of ash trees exclusively, a researcher from Wright State […]

Predatory Wasps and Citizen Scientists are Taking on the Emerald Ash Borer

By Kevin Fitzgerald The emerald ash borer (Agrilus planipennis) is a pest species that has killed tens of millions of ash trees and has the potential to kill most of the 8.7 billion ash trees in North America. The beetle, native to Asia, was accidentally introduced to the U.S. in 2002 in Michigan. Since then, […]
