Emerald Ash Borer Found In NNYPosted: Updated:
State environmental officials say they found the emerald ash borer in two places near the Canadian border.
The specimens were trapped in St. Lawrence and Franklin counties, Department of Environmental Conservation officials said in a release.
This is the first time the invasive pest has been found in northern New York.
Officials say their proximity to the border "may represent an expansion of Canadian infestations into New York."
The emerald ash borer has killed millions of ash trees in the United States.
The larvae kill trees by feeding below the bark and blocking the flow of nutrients to the crown.
The adult beetles leave distinctive D-shape holes when they exit the trees. Other signs are when tree canopies die back and when leaves turn yellow or brown.
"If there's a lot of emerald ash borer larvae in the tree, the woodpeckers will be at it and they'll be picking the bark off and the tree will look a lighter brown and it really gets going," DEC regional forester David Smith said. That's the most distinctive feature of infested trees."
The ash borer is native Asia and was first discovered in North America -- in southeastern Michigan and Windsor, Ontario -- in 2002.
The pests are most common in June and July, but can be found from late May through early September.
The larvae can be moved long distances in firewood, logs, branches, and nursery stock and emerge later to infest new areas.
The state has a regulation barring moving firewood more than 50 miles to prevent the ash borer's spread.
