Spotted Lanternfly

Spotted LanternflyThe Spotted Lanternfly (Lycorma delicatula) is native to China and was first detected in Pennsylvania in September 2014. Spotted lanternfly feeds on a wide range of fruit, ornamental and woody trees, with tree-of-heaven being one of the preferred hosts. Spotted lanternflies are invasive and can be spread long distances by people who move infested material or items containing egg masses. If allowed to spread in the United States, this pest could seriously impact the country’s grape, orchard, and logging industries.

Asian Longhorned Beetle

Asian Longhorned BeetleThe Asian longhorned beetle is native to China and is a wood-boring beetle that infests 12 genera of trees. Adult beetles are 1 to 1.5 inches in length, with long antennae and white spots on their bodies. Adult females chew 60-90 depressions into tree bark and lay a single egg -about the size of a rice grain- per site. Ohio is the fifth state to find Asian Longhorned Beetles. The pest was successfully eradicated in Illinois and parts of New Jersey, and it is currently being controlled in New York and Massachusetts.

Walnut Twig Beetle (WTB) & Thousand Cankers

Walnut Twig BeetleThousand cankers disease (TCD) is caused by a fungus (Geosmithia morbida) carried by the walnut twig beetle (WTB; Pityophthorus juglandis). The fungus and beetle only infest walnut trees; the adult beetle constructs galleries in the phloem, where the fungal spores are introduced. Small cankers then form around the galleries, girdling the branches. The walnut twig beetle is native to Arizona, California, and New Mexico; however the beetle and fungus have been found in eastern states. In 2012 the fungus was found in Butler county, Ohio.

Hemlock Woolly Adelgid

Hemlock Wooly AdelgidHemlock woolly adelgid (Adelges tsugae) is a serious pest of Eastern (Tsuga canadensis) and Carolina (Tsuga caroliniana) hemlocks of all sizes. Native to Asia, HWA was first discovered in North America in British Columbia in 1924. HWA was first reported in the eastern United States in 1951 near Richmond, Virginia. Since then it has been moving steadily through the native hemlock regions of the Appalachian Mountains, from Georgia to Maine, causing extensive mortality and hemlock decline.

In February 2012, the first infestation in a natural stand of hemlock in Ohio was discovered in Meigs County. Since then HWA has been found in hemlock stands in other eastern Ohio counties as well.
