The EFSA Panel on Plant Health performed a pest categorisation of (SDV) for the EU territory. SDV is a well-known pathogen and the type species of the genus in the family Secoviridae. SDV is now considered to include several other formerly distinct viruses which are therefore also covered in the present opinion. Citrus species and their relatives represent the main hosts of SDV and efficient diagnostic techniques are available. SDV is listed on some of its known hosts in Annex IIAI of Directive 2000/29/EC. It is transmitted by vegetative propagation of infected hosts and presumably through the soil, but the precise mechanism or vector(s) are still unknown. SDV is present in Asia and is not known to occur in the EU. Therefore, it does not meet this criterion to qualify as a Union regulated non-quarantine pest (RNPQ). Plants for planting represent the main pathway for the entry, but this pathway is closed by existing legislation for the main hosts (, and ). SDV is, however, able to enter the EU on plants for plants of its unregulated rutaceous or non-rutaceous hosts. Should it be introduced, SDV has the potential to establish and subsequently spread with plants for planting and, possibly, through its poorly characterised natural spread mechanism(s). SDV is able to cause severe symptoms, quality and yield losses on a range of citrus crops. Overall, SDV meets all the criteria evaluated by EFSA to qualify as a Union quarantine pest. The main knowledge gaps and uncertainties concern (1) the potential significance of the unregulated rutaceous and non-rutaceous hosts for virus dissemination and epidemiology, (2) the origin and trade volume of the plants for planting of these host imported in the EU and (3) the efficiency of natural spread of SDV under EU conditions.
欧洲食品安全局植物健康小组对欧盟境内的[具体病毒名称未给出]（SDV）进行了有害生物分类。SDV是一种知名病原体，属于叶蝉病毒科[属名未给出]的模式种。SDV现在被认为包括其他几种以前被视为不同的病毒，因此本意见也涵盖了这些病毒。柑橘属物种及其近缘种是SDV的主要寄主，并且有有效的诊断技术。SDV被列入2000/29/EC号指令附件IIAI中其一些已知寄主名单。它通过受感染寄主的营养繁殖传播，可能也通过土壤传播，但确切机制或传播媒介仍不清楚。SDV存在于亚洲，在欧盟尚未发现。因此，它不符合作为欧盟管制的非检疫性有害生物（RNPQ）的这一标准。种植用植物是其进入的主要途径，但现有针对主要寄主（[寄主名称未给出]、[寄主名称未给出]和[寄主名称未给出]）的立法关闭了这一途径。然而，SDV能够通过其未受管制的芸香科或非芸香科寄主的种植用植物进入欧盟。如果被引入，SDV有可能定殖，随后通过种植用植物传播，并且可能通过其特征不明的自然传播机制传播。SDV能够在一系列柑橘类作物上引起严重症状、质量和产量损失。总体而言，SDV符合欧洲食品安全局评估的所有标准，有资格被列为欧盟检疫性有害生物。主要的知识空白和不确定性涉及：（1）未受管制的芸香科和非芸香科寄主对病毒传播和流行病学的潜在重要性；（2）欧盟进口的这些寄主种植用植物的来源和贸易量；（3）SDV在欧盟条件下自然传播的效率。
