The complete lists were published in EPPO Publication Series B no. 92, November 1988 and since then only one pest has been added to the A2 list, Bemisia tabaci, and one name change has taken place, Xanthomonas ampelina to Xylophilus  ampelinus (see EPPO Reporting Service no. 498/13).        (

Fourteen entries have been deleted from the lists, as being no longer considered worthy of quarantine status; the reasons for the removal of 13 of these were given in Reporting Service 494 on 1988-04-12. The most recent deletion was made in September 1988 and was:

116 Pseudococcus comstocki; Comstock 's mealybug or the white peach scale, was on the A2 list as a pest of mulberry trees (Morus spp.). However, it was noted that it was really only of major economic concern for the silkworm production in the Central Asian republics of the USSR. As it is already present in that country and was of little interest to other countries it was agreed to delete it from the list.
