Abstract
Pear psylla (Cacopsylla pyricola [Foerster] [Hemiptera: Psyllidae]) is an important pest of pear in Washington. Honeydew produced by pear psylla causes fruit russet, and serious infestations can stunt and defoliate trees. Pear psylla likely arrived in the United States along with shipments of pear nursery stock from western Europe. It was first found in Connecticut in 1832 and spread to Washington State by 1939. Within a few years it became a serious pest throughout all pear growing areas in the Pacific Northwest.
