Abstract
The Panel on Plant Health conducted a pest risk assessment for Parasaissetia nigra in the European Union (EU) and identified and evaluated the phytosanitary measures listed in Council Directive 2000/29/EC. Entry through the principal pathways is assessed as moderately likely for plants for planting and very unlikely for living parts of plants, such as fruit and cut flowers with foliage, the discrepancy being mainly due to the difference in probability of transfer to a suitable host. Establishment is rated as very likely outdoors in Mediterranean areas and indoors in the whole risk assessment area (where the pest has been present for a long time), and unlikely outdoors in non-Mediterranean areas. Spread within the EU is considered to be moderately likely because the pest can readily be moved with plant material but is limited by climatic conditions. The magnitude of the potential consequences is rated as minor. The Panel evaluated the effectiveness of current EU phytosanitary measures and concluded that the removal of P. nigra from Annex IIAII would not affect its probability of entry, because the importation from Third countries of some host plants regulated for P. nigra (Citrus, Fortunella, Poncirus species and their hybrids) is prohibited in Annex III. However, spread could be affected since there would no longer be a requirement to inspect for this pest before issuing a plant passport (Annex V). However, since the regulated Rutaceae species constitute only a very small proportion of the potential host plants of P. nigra, the current phytosanitary measures are mostly ineffective in preventing the further introduction and spread of P. nigra in the EU. The Panel identified surveillance at the production site and treatment of the consignment as the most effective and technically feasible risk reduction options, particularly when in combination
