Pest categorisation of Apium virus Y
EFSA Journal 20 (1 - e06930)
Abstract: Following a request from the EU Commission, the EFSA Panel on Plant Health conducted a pest categorisation of Apium virus Y (ApVY) for the EU territory. The identity of the ApVY, a member of the genus Potyvirus (family Potyviridae), is well established and reliable detection methods are available. The pathogen is not included in EU Commission Implementing Regulation 2019/2072. ApVY, considered endemic in Australia, was reported also in New Zealand and USA. In the EU, the virus was identified in Germany and Slovenia. No information on adoption of official control measures is available. In natural conditions, ApVY infects plant species of the family Apiaceae (i.e. celery, coriander, dill, parsley, bishop's weed) in which it generally induces leaf symptoms and/or stunting. In some hosts (i.e. parsley and poison hemlock), ApVY may be asymptomatic. The virus is transmitted in a non-persistent manner by the aphid Myzus persicae which is widespread in the EU. Although ApVY transmission through seeds has been experimentally excluded for some hosts (i.e. poison hemlock and celery), uncertainty exists for the other hosts because seed transmission is not uncommon for potyvirids. Plants for planting, including seeds for sowing, were identified as potential pathways for entry of ApVY into the EU. Cultivated and wild hosts of ApVY are distributed across the EU. Economic impact on the production of the cultivated hosts is expected if further entry and spread in the EU occur. Phytosanitary measures are available to prevent further entry and spread of the virus. Currently, ApVY does not fulfil the criterion of being absent or present with restricted distribution and under official control to be regarded as a potential Union quarantine, unless official control is implemented. This conclusion is associated with high uncertainty regarding the current virus distribution in the EU.
