Ecomonic Importance: This tephritid is considered to be one of the most ser- ious pests of cherries in Europe. It frequently causes severe damage in cen- tral European countries and in recent years has caused severe damage in southern Norway. In Bulgaria in 1929, from 80 to 100 percent of the fruit was damaged in many instances. Infestations in Norway are frequently over 90 percent. Considerable loss occurs in the preserve industry in Germany and further loss is realized in this country from cherry import restrictions operating in Great Britain and other countries. In the past few years it has been inter- cepted in increasing numbers at U. S. ports of entry. As many as 31 intercep- tions have been reported at Atlantic Coast ports in a season. Hosts: The major host is cherry, but it will also attack several other species of Prunus. Lonicera tatarica and L. xylosteum appear to be important alternate hosts, though they are not preferr¥d. Distribution: Occurs throughout most of Continental Europe and parts of Turkey in Asia. In USSR extends from southern Leningrad province to the Crimea and in southeastern i WJs ^_i \ .
