Sažetak
Traditional olive growing along the six thousands kilometers coastal and insular area of Croatia is an economically important source of income for the local population. Recent outbreak of the harmful bacterium Xylella fastidiosa strain CoDiRO over Salento peninsula in Italy represents a potential risk for Croatian olive growing sector. The main agro-ecological and social features of olive growing in Croatia in relation to its vulnerability to the CoDiRO strain of X. fastidiosa are discussed. Olive tree, Olea europaea, is considered as the most endangered crop of CoDiRO strain, and differences in susceptibility among olive cultivars are widely known. Thus, Croatian olive growing that includes over one hundred different varieties are potentially vulnerable to infestations to the CoDiRO strain.. Other subtropical plants that are part of the Mediterranean natural vegetation including cultivated, wild and ubiquitous species that have been proven to be hosts of CoDiRO strain and are growing next to olive orchards represent additional risk factors to infestation of the pathogen due to their high degree of biodiversity and abundance. Moreover, the fact that population of the coastal region is traditionally engaged in agriculture and tourism, facilitates the uncontrolled transmission and planting of plant material of host species in gardens, tourist centers and public spaces. Furthermore five potential vector species [Philaenus spumarius L., Phylaenus signatus L., Lepyronia coleoptrata L. and Aphrophora alni F. (Hemiptera: Aphrophoridae) and Cicadella viridis L. (Hemiptera: Cicadelidae)] have been described in olive growing areas of the under study area. Results of the 2014 survey in Croatia, after extensive visual inspections and laboratory tests, indicated that Xylella fastidiosa strain CoDiRO is not present in Croatia. Presence of potential and confirmed vectors of the pathogen, abundance and high biodiversity of host plants, favorable climate and high movement of plant material are important elements that should be taken into account for the risk assessment of the spread of pathogen in case of his undesirable introduction.
