August is “Tree Check” month. It’s the time when ecologists are out surveying the forests to see if invasive insect species are showing up in the state. Here in Vermont scientists are primarily on the lookout for Asian longhorned beetle, Emerald ash borer, and hemlock woolly adelgid.
So far the longhorned beetle and the emerald ash borer haven’t infiltrated...
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.

DURHAM, New Hampshire — A destructive beetle that targets ash trees — known as the emerald ash borer — may have met its match.
Entomologists believe a wasp may be more effective monitoring the spread of the beetle than standard traps.

Smelling good is just part of what some beetles must do to find a mate. They have to exude the proper perfume at the right time of day and right season of the year, a UA-led team found.
A longhorned beetle’s sexy scent might make a female perk up her antennae. But when the males of several species all smell the same, a female cannot choose by cologne alone.
For these...

The state's new system to confront the invasive emerald ash borer, which relies on quarantine zones drawn around forests known to be infested, is unique among the 25 states in the eastern U.S. where the ash-devouring pest is found.
As a consequence of no longer lining up with federal control rules, the U.S....
Asian carp. Burmese python. Hemlock woolly adelgid. These are just some of the most destructive pests and the world's worst invasive species that raise the hackles of fisherman, farmers, and wildlife managers everywhere they invade.
But how do they establish themselves and take over non-native species so effectively and efficiently?
Knowing answers to these questions could...
As Memorial Day approaches and the summer camping season gets started, take a moment to think about the places that you love and how you can help to protect them. Chances are that trees make up a key component of these places. A spreading sugar maple, a towering ash; trees are vital to many of the places iconic to Vermont and New England.
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, it has spread into the eastern U.S. and southeastern Canada.
