First found in Emilia-Romagna, then in Piemonte, Veneto, Marche, Calabria, Campania.
EPPO Reporting Service (2008/163) : first confirmed record in summer 2007 on onion crops in Emilia-Romagna (provinces of Bologna, Ravenna and Forli-Cesena). An earlier record had been made in Veneto in one plant of Portulaca (Cosmi et al., 2003) but IYSV has not been reported again from that region.
From PPO of Emilia-Romagna (2009-01): in 2008,4 onion fields were found infected by IYSV in Emilia-Romagna. Disease incidence was very low in 3 fields (1-3%) and reached 40-50% in 1 field. Thrips populations were lower than in 2007. Economic impact did not appear significant.
EPPO Reporting Service (2011/017) : detected again in Veneto on 2 onion crops (Allium cepa), no crop loss reported.
EPPO Reporting Service (2011/088) : detected in Piemonte.
According to Zicca et al. (2012), Manglli et al. (2012), Minutolo et al. (2013): also in Veneto, Calabria and Campania.
