The Pennsylvania Department of Agriculture is reporting that a woodboring wasp that attacks pine trees, Sirex noctilio, has been discovered in their state. The wasp is a relatively recent arrival to the U.S., first spotted in New York in 2004. Workers will be monitoring insect traps over the next few weeks to try to get a better idea of just how many wasps there are in the area. In the meantime, Pennsylvania is asking people to help prevent the spread of the wasps by avoiding the transport of firewood or logs away from the areas they originate from.
