Pest categorisation of non-EU viruses and viroids of Vitis L.

ABSTRACT: Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses and viroids of Vitis L. determined as being either non-EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in their biology. With the exclusion of grapevine virus 101-14.N.23.9.1/South Africa/2009 for which very limited information exists, the pest categorisation was completed for 30 viruses or viroids having acknowledged identities and available detection methods. All these viruses are efficiently transmitted by vegetative propagation techniques, with plants for planting representing the major pathway for long-distance dispersal and thus considered as the major pathway for potential entry. Depending on the virus, additional pathway(s) can also be seeds, pollen and/or vector(s). Most of the viruses categorised here are known to infect only one or few plant genera, but some of them have a wide host range, thus extending the possible entry pathways. Grapevine yellow speckle viroid 2, blueberry leaf mottle virus, grapevine Ajinashika virus, grapevine Anatolian ringspot virus, grapevine berry inner necrosis virus, grapevine deformation virus, grapevine fabavirus, grapevine red blotch virus, grapevine stunt virus, grapevine Tunisian ringspot virus, grapevine vein-clearing virus, temperate fruit decay-associated virus, peach rosette mosaic virus, tobacco ringspot virus, tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union quarantine pests (QPs). With the exception of impact for the EU territory, on which the Panel was unable to conclude, blackberry virus S, grapevine geminivirus A, grapevine leafroll-associated virus 7, grapevine leafroll-associated virus 13, grapevine satellite virus, grapevine virus E, grapevine virus I, grapevine virus J, grapevine virus S, summer grape enamovirus, summer grape latent virus satisfy all the other criteria to be considered as potential Union QPs. Australian grapevine viroid, grapevine cryptic virus 1, grapevine endophyte endornavirus and wild vitis virus 1 do not meet all the criteria evaluated by EFSA to be regarded as potential Union QPs because they are not known to cause an impact on Vitis. For several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly because of the absence of data on their biology, distribution and impact. Since this opinion addresses specifically non-EU viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as a potential Union regulated non-quarantine pests.

Project description: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.

Project description:Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses and viroids of Prunus L. determined as being either non-EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in their biology. With the exclusion of Ilarvirus S1 and Ilarvirus S2, for which very limited information exists, the pest categorisation was completed for 26 viruses and 1 viroid having acknowledged identities and available detection methods. All these viruses are efficiently transmitted by vegetative plant propagation techniques, with plants for planting representing the major pathway for long-distance dispersal and thus considered as the major pathway for entry. Depending on the virus, additional pathway(s) can also be Prunus seeds, pollen and/or vector(s). Most of the viruses categorised here are known to infect only one or few plant genera, but some of them have a wide host range, thus extending the possible entry pathways. Apple scar skin viroid, American plum line pattern virus, cherry mottle leaf virus, cherry rasp leaf virus, cherry rosette virus, cherry rusty mottle-associated virus, cherry twisted leaf-associated virus, peach enation virus, peach mosaic virus, peach rosette mosaic virus, tobacco ringspot virus and tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union quarantine pests (QPs). With the exception of impact in the EU territory, on which the Panel was unable to conclude, apricot vein clearing virus, Asian prunus virus 1, Asian prunus virus 2, Asian prunus virus 3, Caucasus prunus virus, cherry virus B, Mume virus A, nectarine stem pitting-associated virus, nectarine virus M, peach chlorotic mottle virus, peach leaf pitting-associated virus, peach virus D, prunus virus F and prunus virus T satisfy all the other criteria to be considered as potential Union QPs. Prunus geminivirus A does not meet the criterion of having negative impact in the EU. For several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly because of the absence of data on their biology, distribution and impact. Since this opinion addresses specifically the non-EU viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non-quarantine pests.

Project description:Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses and viroids of Fragaria L. determined as being either non-EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in their biology. With the exclusion of strawberry latent virus and strawberry latent C virus for which very limited information exists, the pest categorisation was completed for 12 viruses having acknowledged identities and available detection methods. All these viruses are efficiently transmitted by vegetative propagation techniques, with plants for planting representing the major pathway for long-distance dispersal and thus considered as the major pathway for entry. Depending on the virus, additional pathway(s) can also be Fragaria seeds, pollen and/or vector(s). Most of the viruses categorised here are known to infect only one or few plant genera, but some of them have a wide host range, thus extending the possible entry pathways. Strawberry chlorotic fleck-associated virus, strawberry leaf curl virus, strawberry necrotic shock virus, strawberry pallidosis-associated virus, strawberry vein banding virus (SVBV) and tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union quarantine pests (QPs). For SVBV, the Panel considered that following its entry and establishment into the EU territory, an impact of uncertain magnitude is expected mainly because a synergistic effect may occur in strawberry in case of mixed infections with viruses already present in the EU . Strawberry crinivirus 3, strawberry crinivirus 4 and strawberry polerovirus 1 meet all criteria for being considered as potential Union QPs, except for the impact in the EU territory, on which the Panel was unable to conclude. Fragaria chiloensis cryptic virus, Fragaria chiloensis latent virus and strawberry pseudo mild yellow edge virus do not meet the criterion of having potential negative impact in the EU. For several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly because of the absence of data on their biology, distribution and impact. Since this opinion addresses specifically the non-EU viruses, in general, these viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non-quarantine pests.

Project description:The Panel on Plant Health performed a pest categorisation of non-EU Acleris spp. Acleris is a well-defined insect genus in the family Tortricidae (Insecta: Lepidoptera). Species can be identified using taxonomic keys based on adult morphology and genitalia. The genus includes 261 species attacking conifers and non-conifer plants in many areas in the world, among which 40 species are present in the EU. The non-EU species are collectively listed in Annex IAI of Council Directive 2000/29/EC as Acleris spp. (non-European). Some species are important defoliators in North America, mainly on conifers but also on several broadleaf trees. Females lay eggs on the leaves or on the bark. The larvae bind together with silk the leaves upon which they feed. Pupation occurs in leaves attached with silk or in the soil. Some species are univoltine; others are bivoltine or multivoltine. Flight capacity is not documented, but outbreak expansion suggests that the adults can probably fly long distances. The main pathways for entry are host plants for planting with or without soil, cut branches, fruits of host plants (including cones), round wood with bark and bark. The presence of host plants and suitable EU climate would allow the establishment of the known non-EU harmful species. In the literature, nine non-EU Acleris species are reported as pests on various host plants, namely A. gloverana, A. variana, A. minuta, A. nishidai, A. issikii, A. semipurpurana, A. robinsoniana, A. senescens and A. nivisellana. These non-EU Acleris spp. satisfy all the criteria to be considered as Union quarantine pests. Concerning the other 212 non-EU Acleris species, there is scarce information on host plants, pests status and climatic suitability. Measures are in place to prevent the introduction of non-EU Acleris spp. through the pathways described in the document. As non-EU Acleris spp. are not present in the EU and plants for planting are not the major pathway for spread, non-EU Acleris spp. do not meet the criteria to be considered as regulated non-quarantine pests.

Project description:Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of Arceuthobium spp. (non-EU), a well-defined and distinguishable group of parasitic plant species of the family Viscaceae, also known as dwarf mistletoes. These are flowering plants parasitising a wide range of conifers of the families Pinaceae and Cupressaceae. Arceuthobium species (non-EU) are regulated in Council Directive 2000/29/EC (Annex IAI) as harmful organisms whose introduction into the EU is banned. Many Arceuthobium species are recognised, with most dwarf mistletoes native in the New World, and north-western Mexico and the western USA as the centre of diversity for the genus. Only two Arceuthobium species are native (and reported to be present) in the EU (Arceuthobium azoricum and Arceuthobium oxycedrum), which are thus not part of this pest categorisation. Hosts of non-EU dwarf mistletoes include species of the genera Abies, Cupressus, Juniperus, Larix, Picea, Pinus, Pseudotsuga and Tsuga. Most Arceuthobium spp. can parasitise more than one species of conifer host. Dwarf mistletoes could enter the EU via host plants for planting and cut branches, but these pathways are closed. They could establish in the EU, as hosts are widespread and climatic conditions are favourable. They would be able to spread following establishment by human movement of host plants for planting and cut branches, as well as natural spread. Should non-EU dwarf mistletoes be introduced in the EU, impacts can be expected on coniferous woodlands, plantations, ornamental trees and nurseries. The main uncertainties concern (i) the precise distribution and host range of the individual Arceuthobium spp. and (ii) the level of susceptibility of conifers native to Europe. For Arceuthobium spp. (non-EU) as a group of organisms, the criteria assessed by the Panel for consideration as a potential quarantine pest are met, while, for regulated non-quarantine pests, the criterion on the pest presence in the EU is not met.
