“…The percentage of crawlers settling on a tree from an infested fruit is higher when the infested commodity (e.g. a fruit) is in contact with the tree than when it is placed 2 m away (Hennessey et al, 2013). However, crawlers may be carried to neighbouring plants by wind (Waterhouse and Sands, 2001) or by hitchhiking on clothing, equipment or animals (Hennessey et al, 2013;Leathers, 2016).…”

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by 2‐year‐old bare rooted plants for planting of Acer palmatum grafted on rootstocks of Acer davidii imported from China to the EU, taking into account the available scientific information, including the technical information provided by China. All pests associated with the commodity were evaluated against specific criteria for their relevance for this Scientific Opinion. Twenty‐two pests that fulfilled all relevant criteria were selected for further evaluation. For 20 pests, the risk mitigation measures described in the technical dossier from China were evaluated taking into account the possible limiting factors. For these pests, an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. While the estimated degree of pest freedom varied among pests, Lopholeucaspis japonica was the pest most frequently expected on the commodity. The Expert Knowledge Elicitation indicated, with 95% certainty, that 9,336 or more bare rooted plants per 10,000 will be free from L. japonica . For Anoplophora chinensis and Anoplophora glabripennis , the Panel considers that China applies the relevant measures as specified in Commission Implementing Decision (EU) 2012/138 and Commission Implementing Decision (EU) 2015/893.

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers the plant health risks posed by the following commodities: i) dormant and free of leaves 1‐year‐old bare rooted plants and ii) free of leaves 1‐year‐old liners of Ficus carica imported from Israel, taking into account the available scientific information, including the technical information provided by Israel. The relevance of any pest for this opinion was based on evidence following defined criteria. Four EU quarantine pests, Euwallacea fornicatus, Hypothenemus leprieuri, Scirtothrips dorsalis and Spodoptera frugiperda, and 11 EU non‐regulated pests fulfilled all relevant criteria and were selected for further evaluation. For these pests, the risk mitigation measures proposed in the technical dossier from Israel were evaluated separately for bare rooted plants and for liners, taking into account the possible limiting factors. For these pests, an expert judgement was given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. The estimated degree of pest freedom varied among the pests evaluated. Aonidiella orientalis and Russellaspis pustulans were the most frequently expected pests on the imported bare rooted plants, and Scirtothrips dorsalis on liners. The Expert Knowledge Elicitation indicated, with 95% certainty, that between 9,585 and 10,000 bare rooted plants per 10,000 would be free of Aonidiella orientalis and Russellaspis pustulans and between 9,456 and 10,000 liners per 10,000 would be free of Scirtothrips dorsalis.

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation EU/2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers all plant health risks posed by unrooted cuttings of Jasminum polyanthum produced in a protected environment (greenhouse) that are imported from Israel, taking into account the available scientific information, including the technical information provided by the NPPO of Israel by 15 March 2020. The relevance of an EU quarantine pest for this opinion was based on evidence that: (i) the pest is present in Israel; (ii) Jasminum is a host of the pest; and (iii) the pest can be associated with the commodity. The relevance of any other pest, not regulated in the EU, was based on evidence that: (i) the pest is present in Israel; (ii) the pest is absent in the EU; (iii) Jasminum is a host of the pest; (iv) the pest can be associated with the commodity and (v) the pest may have an impact and can pose a potential risk for the EU territory. Six species, the EU‐quarantine pest Scirtothrips dorsalis, and the EU non‐regulated pests Aonidiella orientalis, Milviscutulus mangiferae, Paracoccus marginatus, Pulvinaria psidii and Colletotrichum siamense fulfilled all relevant criteria and were selected for further evaluation. For these pests, the risk mitigation measures proposed in the technical dossier from Israel were evaluated taking into account the possible limiting factors. For these pests, an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. The estimated degree of pest freedom varies among the pests evaluated, with S. dorsalis being the pest most frequently expected on the imported plants. The Expert Knowledge Elicitation indicated, with 95% certainty, that between 9,958 and 10,000 bags per 10,000 would be free of S. dorsalis.
