Scientific Opinion on the pest categorisation of the tospoviruses


The European Commission requested EFSA’s Panel on Plant Health to perform the pest categorisation for the 24 viruses of the Tospovirus genus for the EU territory. The following tospoviruses were analysed: Tomato spotted wilt virus(TSWV), Impatiens necrotic spot virus (INSV), Iris yellow spot virus (IYSV), Polygonum ringspot virus (PolRSV), Groundnut ringspot virus (GRSV), Tomato chlorotic spot virus (TCSV), Alstroemeria necrotic streak virus (ANSV), Chrysanthemum stem necrosis virus (CSNV), Melon severe mosaic virus (MSMV), Tomato yellow (fruit) ring virus (TYRV), Tomato zonate spot virus (TZSV), Groundnut yellow spot virus (GYSV), Groundnut chlorotic fan-spot virus (GCFSV), Groundnut bud necrosis virus (GBNV), Zucchini lethal chlorosis virus (ZLCV), Capsicum chlorosis virus (CaCV), Watermelon bud necrosis virus(WBNV), Watermelon silver mottle virus (WSMoV), Tomato necrotic ringspot virus (TNRV), Calla lily chlorotic spot virus (CCSV), Melon yellow spot virus (MYSV), Soybean vein necrosis associated virus (SVNaV), Bean necrotic mosaic virus (BeNMV) and Pepper necrotic spot virus (PNSV). In reaching its conclusions, the Panel considered four parameters to be of critical importance in the risk assessment area: (i) the presence of a tospovirus, (ii) the existence of host plants, (iii) the existence of thrips vector species and (iv) the potential for damage to crops grown in Europe. Based on its analysis, the Panel concluded that the 24 viruses analysed could be allocated to four different risk groups. Seven viruses (GRSV, TCSV, ANSV, CSNV, MSMV, TYRV, TZSV) for which both thrips species vectors and natural or experimental hosts crops are present in the EU territory were considered by the Panel to represent the highest risk to the EU territory. In contrast, three viruses (INSV, IYSV and PolRSV) already present in the risk assessment area were not considered by the Panel to pose a risk justifying the development of full risk assessments.
