Abstract
Several major imported insect pests have in recent years been found in Pennsylvania, including the Japanese beetle (Popillia japonica Newm.), the European corn borer (Pyrausta nubilalis Hubn.), the Mexican bean beetle (Epilachna corrupta Muls.), and the Oriental fruit moth (Laspeyresia molesta Busck). Each of these species is apparently slowly spreading and increasing in economic importance. Two other species, the imported Willow leaf beetle (Plagiodera versicolora Laich) and the Apple and thorn skeletonizer (Hemerophila pariana Clerck), have both been found but have not as yet assumed a position of major economic importance.
