Forest Pests in Kentucky's Parks Survey: 2013 - 2018
In addition to the tourism aspect of Kentucky’s parks system, Kentucky’s forest and wood industry is extremely important to the state. In 2012, that industry added $9.9 billion to the economy and employed over 51,000 Kentuckians. Kentucky is the leading producer of hardwood timber in the south and one of the top three in the United States (KY Forest Economic Impact Report 2012-2013).
The pests for which we will survey are moth pests of oak trees so establishment of any of the pests could impact the tourism, ecology, and economy within the state greatly.
Rosy Gypsy Moth
2013 was the first year of this survey and 22 state parks were included. From 2013-2016, we conducted a survey that consisted of both a trapping component and a visual survey component. The trapping component of the survey was designed to detect eight moth pests that pose a risk to oak trees since 75% of Kentucky’s forestland, a total over 9.3 million acres, is an oak-hickory forest type (statistics from forestry.ky.gov). These eight pests are as follows: Summer Fruit Tortrix, Variegated Golden Tortrix, Light Brown Apple Moth, Rosy Moth, Egyptian Cottonworm, Oak Processionary Moth, False Codling Moth, and Green Oak Tortrix. In 2016, Light Brown Apple Moth was not included in the survey. In 2017, Summer Fruit Tortrix was not included in the survey and the visual survey component was removed. Pests included in the survey in 2018 were: Variegated Golden Tortrix, Oak Processionary Moth, Green Oak Tortrix, False Codling Moth, and Rosy Moth.
The visual survey component from 2013-2016 involved looking for signs and symptoms of two pests of state concern, the Hemlock Woolly Adelgid and Asian Longhorned Beetle. Hemlock trees are common in forests in the eastern one-third of Kentucky and Hemlock Woolly Adelgid was discovered first discovered in Kentucky in 2006. Asian Longhorned Beetle has been found in southeastern Ohio relatively near the Kentucky border.
During the survey, surveyors looked for trees showing signs of Asian Longhorned Beetle (ALB) infestation. Surveyors did not see any trees that appeared to be infested with this pest, but did not county numbers of negative trees since they could not thoroughly examine the entire tree to say with certainty that it was free of ALB.
