Pest categorisation of Grapholita inopinata
The EFSA Panel on Plant Health (PLH) performed a pest categorisation of Grapholita inopinata,
(Lepidoptera: Tortricidae), the Manchurian fruit moth, for the territory of the EU. G. inopinata is a welldefined species that is recognised as a major pest of Malus spp. in Far East Russia, Eastern Siberia and
northern China. G. inopinata is less common in Japan where it is not a serious pest. G. inopinata is not
known to occur in the EU. G. inopinata is listed in Annex IIAI of 2000/29 EC as a harmful organism
regulated on Cydonia, Malus, Prunus and Pyrus from non-European countries. Adult G. inopinata
emerge in the summer, mate and lay eggs on host leaves and fruit. Larvae burrow into the fruit to
develop. Larvae exit fruit and overwinter under bark, under leaf litter or in the soil. Import of host fruit
provides a potential pathway into the EU. Restrictions on the import of host plants for planting close
other potential pathways. G. inopinata occurs in a range of climates in Asia, some of which also occur
in the EU. Wild and commercially grown hosts are available within the EU. G. inopinata has the
potential to establish within the EU. There could be one or two generations per year as in its native
range. Impacts could occur in pome fruit orchards. The level of impacts would be uncertain.
Phytosanitary measures are available to reduce the likelihood of introduction of G. inopinata.
G. inopinata meets all the criteria assessed by EFSA PLH to satisfy the definition of a Union quarantine
pest. G. inopinata does not meet the criteria of occurring within the EU, nor plants for planting being
the principal means of spread, so does not satisfy all the criteria for it to be regarded as a Union
regulated non-quarantine pest (RNQP)
Pest categorisation of Septoria malagutii
The Panel on Plant Health performed a pest categorisation of Septoria malagutii, the causal agent of
annular leaf spot of potato, for the EU. The pest is a well-defined fungal species and reliable methods
exist for its detection and identification. S. malagutii is present in Bolivia, Ecuador, Peru and Venezuela.
The pest is not known to occur in the EU and is listed as Septoria lycopersici var. malagutii in Annex
IAI of Directive 2000/29/EC, meaning its introduction into the EU is prohibited. The major cultivated
host is Solanum tuberosum (potato), but other Solanum species including wild solanaceous plants are
also affected. All hosts and pathways of entry of the pest into the EU are currently regulated. Host
availability and climate matching suggest that S. malagutii could establish in parts of the EU and
further spread mainly by human-assisted means. The pest affects leaves, stems and petioles of potato
plants (but not the underground parts, including tubers) causing lesions, leaf necrosis and premature
defoliation. In some infested areas, the disease has been reported to cause almost complete crop loss
with favourable weather conditions and susceptible potato cultivars. The introduction of the pest into
the EU would potentially cause impacts to potato production. The main uncertainties concern the host
range, the maximum period the pest survives on host debris in soil, the maximum distance over which
conidia of the pest could be dispersed by wind-driven rain and the magnitude of potential impacts to
the EU. S. malagutii meets all the criteria assessed by EFSA for consideration as potential Union
quarantine pest. The criteria for considering S. malagutii as a potential Union regulated non-quarantine
pest are not met, since the pest is not known to occur in the EU
Pest categorisation of Stenocarpella maydis
The EFSA Plant Health Panel performed a pest categorisation of Stenocarpella maydis, a clearly defined fungus causing seedling blight, stalk and ear rot in maize, its only confirmed main host. The pathogen occurs in many countries of North, Central and South America, Africa, Asia and Oceania where maize is grown commercially. It is present in the EU with restricted distribution (Czech Republic and Spain). Stenocarpella maydis is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting (maize seeds) is the main pathway of entry and spread in the EU. Host availability and climate are favourable for the establishment of the pathogen in maizeâgrowing areas of the EU. The pathogen has a direct impact on yield and quality of maize production. Phytosanitary measures are available to mitigate further introduction and spread of the pathogen into the EU. The Panel concludes that S. maydis satisfies all the criteria to be regarded as a potential Union quarantine pest
