American plum line pattern virus detected again in Italy

The NPPO of Italy recently informed the EPPO Secretariat that the American plum line pattern virus (Ilarvirus, APLPV - EPPO A1 List) has been detected in the Piemonte region. During indexing studies carried out in spring 2009 on flowering cherry trees (Prunus serrulata), 2 symptomatic plants were noticed in the municipality of Verbania (province of Verbano-Cusio-Ossola). Laboratory analysis (ELISA and RT-PCR) confirmed the presence of APLPV. It can be recalled that APLPV had been detected on a small number of Prunus samples collected from Puglia and Sicilia, as well as from other Mediterranean countries (EPPO RS 2003/118).

EPPO note: more studies are needed to understand better the current situation of this North American virus in Europe and in particular to assess its impact on Prunus crops.
