Olive (Olea europaea) is host of 13 different viruses but, it is possible that
other viruses, which are either non mechanically transmissible or occur in low
concentration in plant tissues, are present in nature. This likelihood is supported by
the widespread occurrence of double-stranded RNAs (dsRNAs) in plants negative to
biological tests. As very little information is available on the geographical
distribution of olive-infecting, investigations were conducted for gathering
information on the prevalence and distribution of olive viruses in the Mediterranean
basin based on the presence of double stranded RNA (dsRNA). A total of 527
samples were collected throughout the surveys covering 10 countries and 83
locations. Out of 286 tested samples collected from 6 Italian regions, 210 (73.4%)
were dsRNA positive, whereas the average of viral infections in the Mediterranean
basin was 64.5%. Molecular hybridisation tests, on 25 % of dsRNA-positive samples
collected in Apulia, revealed the presence of the three nepoviruses (ArMV, CLRV
and SLRSV), OLYaV and OLV-1.
