2.7.18 – U.S. Secretary of Agriculture Sonny Perdue released $17.5 million in emergency funds to help bring an end to the spread of the Spotted Lanternfly in southeastern Pennsylvania. The action is the result of an upsurge of the invasive species in Pennsylvania, which saw the number of affected square miles increase from 174 in 2016 to approximately 3,000 in 2017. As a result, the U.S. Department of Agriculture (USDA) has been working with the Pennsylvania Department of Agriculture (PDA) to develop an area-wide approach to fight the Spotted Lanternfly before the invasive species re-emerges this spring.
