“…The risk for the EU territory from CaCV and several other tospoviruses was assessed ‘as limited but with significant uncertainty’. In addition, it was stressed ‘that new experimental data on the vector range of a particular virus, or changes in the geographical distribution or prevalence of vector species, could necessitate the reallocation of viruses in this category to a higher risk category’ (EFSA PLH Panel, 2012 ). In the present pest categorisation, new data and information on vectors and geographic distribution that may reduce the uncertainty highlighted in the conclusions of the previous pest categorisation are taken into consideration.…”

The EFSA Panel on Plant Health conducted a pest categorisation of Capsicum chlorosis virus (CaCV) for the EU territory. The identity of CaCV, a member of the genus Orthotospovirus (family Tospoviridae ), is established and reliable detection and identification methods are available. The pathogen is not included in the EU Commission Implementing Regulation 2019/2072. CaCV has been reported in Australia, China, India, Iran, Taiwan, Thailand and USA (Hawaii). In the EU, it has been reported once in Greece (Crete Island). The NPPO of Greece reported that CaCV is no longer present in Greece. CaCV infects plant species in the family Solanaceae (i.e. pepper, tomato) and several species of other families, including ornamentals. It may induce severe symptoms on its hosts, mainly on leaves and fruits, which may become unmarketable. The virus is transmitted in a persistent propagative mode by the thrips Ceratothripoides claratris, Frankliniella schultzei, Microcephalothrips abdominalis and Thrips palmi. C. claratris and T. palmi are EU quarantine pests. M . abdominalis is known to be present in several EU member states and it is not regulated in the EU. Plants for planting, parts of plants, fruits and cut flowers of CaCV hosts, and viruliferous thrips were identified as the most relevant pathways for the entry of CaCV into the EU. Cultivated and wild hosts of CaCV are distributed across the EU. Should the pest enter and establish in the EU territory, impact on the production of cultivated hosts is expected. Phytosanitary measures are available to prevent entry and spread of the virus in the EU. CaCV fulfils the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

“…The following viruses and viroids have been addressed by EFSA in previous scientific opinions: beet curly top virus (EFSA PLH Panel, 2017), capsicum chlorosis virus (EFSA PLH Panel, 2012a), cherry rasp leaf virus (EFSA PLH Panel, 2013a,b, 2019a, chrysanthemum stunt viroid (EFSA PLH Panel, 2011, 2012b, groundnut bud necrosis virus (EFSA PLH Panel, 2012a), groundnut ringspot virus (EFSA PLH Panel, 2012a), tomato chlorotic spot virus (EFSA PLH Panel, 2012a), tomato planta macho viroid (EFSA PLH Panel, 2011), tomato ringspot virus (EFSA PLH Panel, 2013a, tomato yellow leaf curl virus (EFSA PLH Panel, 2013b, 2014, tomato yellow ring virus (EFSA PLH Panel, 2012a), tomato zonate spot virus (EFSA PLH Panel, 2012a).

Pest categorisation of non‐EU viruses and viroids of potato

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of those viruses and viroids (hereafter referred to as viruses) of Solanum tuberosum and other tuber-forming Solanum spp. (hereafter referred to as potato) which are considered to be either non-EU or of undetermined standing based on a previous EFSA opinion. These viruses belong to different families and genera and either have an established identity or produce consistent symptoms. Plants for planting is the main pathway for entry for all categorised viruses as they can all be transmitted by vegetative propagation. Several categorised viruses have a relatively wide host range and/or are vector-transmitted, increasing the potential for entry. The information currently available on geographical distribution, biology, epidemiology, impact and potential entry pathways has been evaluated with regard to the criteria to qualify as potential Union quarantine pest or as Union regulated non-quarantine pest (RNQP). Since this opinion addresses specifically the non-EU potato viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non-quarantine pests. The following viruses meet the criteria to qualify as potential Union quarantine pest: APLV, APMMV, APMoV, ChiLCV, CYSDV, PAMV, PBRSV, PVH, PVP, PVT, PYDV, PYMV, PYV, PYVV, RCVMV, SALCV, SB26/29, ToCV, ToLCNDV, ToMHaV, ToMoTV, ToSRV and ToYVSV. With the exception of the criterion regarding the potential for consequences in the EU territory, for which the Panel is unable to conclude because of lack of information, AVB, CPSbV, PaLCrV, PapMV, PVB, PVU, SB41 and TVBMV meet all the other criteria to qualify as potential Union quarantine pest. PotLV and WPMV do not qualify as potential Union quarantine pest, since they are not reported to have any impact. For most of the categorised viruses, the conclusions of the Panel have inherent uncertainties, due to the lack of quantitative data on their impact and/or absence or limited availability of information on the biology, epidemiology and geographical distribution.

“…dorsalis is also an efficient vector of many viruses and, in particular, of three tospoviruses: groundnut bud necrosis virus (GBNV), groundnut chlorotic fan-spot virus (GCFSV) and groundnut yellow spot virus (GYSV) (EFSA PLH Panel, 2012). Host plants for these viruses are not grown in the EU.…”

Scientific Opinion on the pest categorisation of Scirtothrips dorsalis

The EFSA Panel on Plant Health undertook a pest categorisation for the insect Scirtothrips dorsalis for the European Union. Although there are reports that this is a species complex and there are host-specific races, it is generally treated as a distinct taxon. Both morphological and molecular methods are required to confirm identification. Apart from one long-term outbreak in a botanic garden glasshouse in England, it is absent from the EU. Native to southern and eastern Asia, this species has been introduced to tropical and subtropical areas of Africa, Australasia and the Americas in recent years. It is highly polyphagous, with over 225 known hosts, which include many important EU crops. Southern areas of the EU are potentially suitable for outdoor establishment and it could establish in protected cultivation throughout the EU. Based on its phenology, the Panel showed that the climate in southern Europe could allow a similar number of generations to develop as in Japan and South Korea, where significant damage occurs to citrus and other crops outdoors. In protected cultivation, even though control methods used against other thrips species may be effective in keeping populations at low densities, damage can still occur at these densities owing to the transmission of tospoviruses. Despite being highly polyphagous, S. dorsalis is an insect listed in Annex IIAI of Council Directive 2000/29/EC only in relation to Citrus, Fortunella and Poncirus plants. These hosts are also regulated in Annex III and Annex V. They are also explicitly mentioned in Council Directive 2008/90/EC.
