摘要：The Panel on Plant Health conducted a pest risk assessment for Eutetranychus orientalis in the European Union (EU) and evaluated the effectiveness of phytosanitary measures in Council Directive 2000/29/EC. Entry through the plants for planting pathway is assessed as very likely, while entry through other pathways is estimated as moderately likely to unlikely owing to the different probability of transfer to a suitable host. Establishment is rated as very likely in Mediterranean areas and from moderately likely to unlikely in non-Mediterranean areas, because of unfavourable environmental conditions. Spread is rated as very likely because of the many ways the pest can spread, its polyphagy and the wide distribution of hosts. Impact is rated as minor, with an expected increase in the damage when populations of natural enemies are severely affected by control measures and/or when environmental conditions are stressful for the host. However, the lack of information resulted in an overall medium level of uncertainty. The Panel evaluated the effectiveness of current EU phytosanitary measures and concluded that the removal of E. orientalis from Annex IIAII would not affect its probability of entry, because the importation from Third countries of some host plants regulated for this pest(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 an extremely small proportion of the potential host plants of E. orientalis, the current phytosanitary measures are mostly ineffective in preventing further introduction and spread of E. orientalis 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 applied together.
