Likelihood of entry is: likely via ornamental shrubs from (southern) Europe. Likelihood of establishment is: likely both outdoors or in protected conditions such as polytunnels. 

Rate of spread is expected to be: very quick via trade, leading to many satellite populations which would then slowly spread naturally. 

Economic impact is expected to be: very small. Cosmetic damage may occur if populations build up in neglected (unmanaged) areas (as was the case in Germany). Environmental impact is expected to be: NIL 

Endangered area: No significant economic impact is expected so no endangered area is identified. Risk management: The horticultural industry is likely to be able to control O. meridionalis just as well as it controls other root weevils i.e. using a mixture of biopesticides and conventional chemical treatments when necessary.
