The ‘Green Industry’ in Pennsylvania comprises over 25% of the state’s total agriculture sales. As a part of the ‘green industry,’ conifer production in PA is ranked fifth in the nation, with a total of $41,763,000 in conifer and Christmas tree sales for 2003 (USDA, 2003). These sales come from over 1,200 farms across the state.
A major economic pest facing Pennsylvania growers is the white pine weevil (WPW), Pissodes strobi, (Peck). It is the most damaging of the weevil pests associated with Christmas tree production and conifer nursery stock.
