HARRISBURG, Pa. (AP) — The invasive spotted lanternfly is continuing its westward march across Pennsylvania. State agriculture officials are nearly doubling the number of counties in a quarantine zone. A dozen counties were added to the list Tuesday, including Beaver and Allegheny  counties. Twenty-six of Pennsylvania’s 67 counties are now under quarantine, requiring businesses that move products, vehicles and other items in and out of the quarantine zone to obtain a permit. Native to Asia, the large, colorful planthopper sucks sap from valuable trees and vines, weakening them.
