摘要：The Panel on Plant Health conducted a pest risk assessment for Tomato spotted wilt virus (TSWV) including the identification and evaluation of risk reduction options. The plants for planting pathway is considered the most important one and rated as likely, with medium uncertainty. TSWV, reported in many Member States, has one of the widest host range for plant viruses and has three widely distributed thrips vector species in the risk assessment area. For countries falling under the provisions of 2000/29/EC Annex IIAII legislation, the probability of establishment is rated as very likely, with low uncertainty. For Finland and Sweden, protected zone under the 2000/29/EC Annex IB legislation, the probability of establishment is rated unlikely to moderately likely. Spread can occur through the activity of thrips vectors and through trade of infected hosts. The probability of spread in Member States under Annex IIAII provisions is evaluated as likely, with low uncertainty. In Finland and Sweden, spread is rated as unlikely to moderately likely, with medium uncertainty. Since TSWV may cause both yield and quality losses in a wide range of hosts, a major impact is predictable in the absence of appropriate control measures, with medium uncertainty. The risk reduction options evaluated by the Panel are those addressing either the sanitary status of the propagation material (including the provisions of 2000/29/EC Annex IIAII and Annex IB, statutory certification system and the use of voluntary industry standards) or those addressing the control of TSWV epidemic development through actions directed at the virus or at its vectors (including cultural methods to reduce crop infestation and chemical or biological control of thrips vectors). Limitations of the current measures and the potential consequences of repealing the current legislation are discussed.
