A little over a month ago, the first Emerald Ash Borer, Agrilus planipennis, was found in Washington State. This is devastating news, because this invasive metallic green beetle is essentially a death sentence for the ash trees of the Pacific … Continue reading →

The emerald ash borer (Agrilus planipennis), one of the most destructive invasive pests of ash trees, is moving closer to Central Europe. It was recently detected in Hungary, while its presence is…

A tiny Asia-origin beetle that has devastated ash forests in North America has been detected in the European Union for the first time in Hungary and Slovakia, authorities have said.

The emerald ash borer (EAB), Agrilus planipennis, is the most destructive forest pest to have invaded North America this century and now has been discovered for the first time in the European Union.

A single invasive species, barely half an inch long, has killed millions of ash trees (Fraxinus spp.) across the United States since 2002. The emerald ash borer (Agrilus planipennis), a metallic-green insect native to eastern Asia, now infests at least 38 states and the District of Columbia. The Cary Institute of Ecosystem Studies calls it the most destructive and costly forest insect ever to invade North America. A second, less understood disease called ash yellows adds a separate threat to the same trees across parts of the Northeast and Midwest. The Beetle Behind the Damage The emerald ash borer, known as EAB, does almost none of its damage as an adult. Adult beetles feed lightly on ash foliage from late spring through early fall and leave few visible marks on the tree. They are about a third to half of an inch long, and the beetle is easy to miss even at close range. The real destruction happens underneath the bark: females lay eggs in bark crevices, and the larvae that hatch tunnel through the inner bark, carving S-shaped wounds that cut off the tree's flow of water and nutrients. The Signs of an Infected Ash Tree Homeowners and foresters...

A Nébih június végi laborvizsgálata megerősítette a kőrisrontó karcsúdíszbogár (Agrilus planipennis) jelenlétét Beregsurány térségében. A feromoncsapda két kifejlett példányt fogott. A zárlati kártevő tömeges kőrispusztítást okozhat, ami erdőgazdálkodási és faanyagpiaci veszteségeken át a helyi költségeket is megemelheti a Pénzcentrum szerint.
