Happy Valley Vineyard and Winery owner Barbara Christ stands among ten acres of grapevines on neat rows of trellises.
She points to a post at the end of one row of vines as a perfect location for an unwelcome visitor.
“They would definitely lay egg masses on something like this," she said.
Christ is a retired Penn State plant pathology professor whose research focused on plant diseases. As a vineyard owner, she’s keeping an eye out for the spotted lanternfly.
“It could be extremely devastating to an operation like ours,” Christ said.
