Pests and Disease

Tests Show Wheat Gene Increases Blight Resistance of Chestnut Trees

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), working collaboratively with scientists funded by The American Chestnut Foundation, have helped confirm that addition of a wheat gene increases the blight resistance of American chestnut trees.

Pennsylvania plans for hemlock protection

The hemlock woolly adelgid poses a grave threat to the eastern hemlock tree and state forestry officials are mounting an effort to combat it.

The Pennsylvania Department of Conservation and Natural Resources (DCNR) is honing a conservation plan to save the eastern hemlock, the official state tree since 1931. It will rely on cooperation from private landowners who own a considerable amount of forest acreage in Pennsylvania.

Emerald Ash Borer Confirmed in Five Counties in Southern Iowa

Emerald Ash Borer (EAB) has been positively identified in Appanoose, Lucas, Mahaska, Marion and Monroe counties in southern Iowa. EAB kills all ash tree species and is considered to be one of the most destructive tree pests ever seen in North America.

One-Two Punch Slows Down the Hemlock Woolly Adelgid

Can combining chemical and biological treatments save eastern hemlocks from the hemlock woolly adelgid?

Recently published research by U.S. Forest Service scientists and collaborators offers hope that integrated management can provide sustained protection for an iconic tree.

Predicting the next gypsy moth devastation

Gypsy moth caterpillars consume the leaves of deciduous tree species, most preferably oak and maples. During heavy infestations, I have seen them devour the leaves of practically every type of tree. This is one of the reasons why several Pocono communities, with large tracts of forested land, are concerned about another outbreak of gypsy moth caterpillars such as we experienced a few years ago.

Thousand cankers disease could cost black walnut industry millions

Several states are trying to protect their borders from a little beetle that could cost the black walnut industry millions of dollars. Thousand cankers disease has been confirmed in Colorado, New Mexico, Arizona, Vermont, Nevada, California, Idaho, Washington, Pennsylvania, Tennessee, North Carolina and Virginia.

Southern Pine Beetle Confirmed For the First Time in New York State

New York agencies have confirmed the presence of southern pine beetle (SPB) in three locations along the southern shore of Long Island. Personnel from multiple agencies worked together to verify the presence of this destructive beetle after the discovery of dead and dying pine trees in portions of the Wertheim National Wildlife Refuge, Connetquot River State Park and the Henry's Hollow Pine Barrens State Forest. This is the first detection of SPB in New York State.

Scientists are looking for emerald ash borer "survivor trees" in Michigan

Researchers with the USDA Forest Service are looking for ash trees that survived the attack of the emerald ash borer.

The invasive insect has been spreading across the Midwest and beyond since 2002, killing millions of ash trees in its wake. 

The Northern Research Station has launched a new online reporting tool. They want people in 10 counties in southeast Michigan and 7 counties in northwest Ohio to report the location of ash trees that have survived the infestation.

Michigan State Forester Fighting Oak Wilt with the USDA Forest Service

Photo by Ronald MurrayOak trees can be found all over the world, but they save their full display for the United States. More than 50 species of oak grow from coast to coast, and in a few unique places like Michigan, still form the basis for a rare and valuable ecosystem known as oak savannas.

Emerald Ash Borer May be Infecting More Than Just Ash Trees

The emerald ash borer, which is destroying ash trees in a large swath of the nation, has apparently spread to a different tree, a researcher at Wright State University suspects.

Biology professor Don Cipollini, Ph.D., director of the Environmental Sciences Ph.D. Program, has found that the invasive green beetle has apparently begun to attack white fringetree.
