As some of you may have heard a colony of spotted lanternfly, an invasive and highly destructive tree hopping insect, was found in Mingo Junction in Jefferson County. The first report was from a citizen on October 19th. Ohio Department of Agriculture employees found more nearby.
SLF is a great concern to the grape and wine industry. The insect is fond of grapevines, fruit trees, hops, blueberry, oak, pine, poplar, and walnut. Adult SLF are attracted to the invasive Ailanthus tree, also known as tree-of-heaven, while nymphs feed on a wide range of hosts. Both adults and nymphs feed on stems and leaves, causing sap bleeding and reduced photosynthesis, which can eventually kill the plant.
