Desperate for wood for its central South Carolina mill, International Paper Co. has begun harvesting from Virginia, New York and Massachusetts -- states infested with gypsy moths, which defoliate a million acres of trees each year in the U.S. USDA has promised to work with International Paper on moth inspections of trees imported to the South for processing to avoid bringing the insect to South Carolina.
