[email protected] ORLINSKI Andréi (Mr) This PRA was reviewed by the EPPO Panel on Phytosanitary Measures on 2013-03-05/07 2 Summary of the Express Pest Risk Analysis for Agrilus planipennis PRA area: EPPO region Describe the endangered area: Fraxinus spp. are present throughout the EPPO region, including Russia, the southernmost part of Finland, Norway, and Sweden, although Fraxinus is more widespread (and with a larger number of species) in the north, central and eastern parts of the EPPO region. Impact is likely to occur throughout the natural and planted range of ash in the EPPO region. Main conclusions Overall assessment of risk: The likelihood of entry is considered as moderate, and the likelihood of establishment as high. Where it is introduced, the pest is likely to cause major losses and environmental impact, and some social effects. Long-distance spread will be via human-assisted pathways, although natural spread will happen but at a slower pace. Where A. planipennis is introduced, it will have massive impact, and eradication or containment will be difficult and costly, and very unlikely to be successful. Phytosanitary Measures: the pest should be recommended for immediate action in the PRA area. Measures were identified for the following pathways: wood, wood waste, wood chips, plants for planting, bark, furniture and cut branches. Phytosanitary risk for the endangered area (Individual ratings for likelihood of entry and establishment, and for High Moderate Low magnitude of spread and impact are provided in the ⊠ ☐ ☐ document) Level of uncertainty of assessment (see Q 17 for the justification of the rating. Individual ratings High Moderate Low of uncertainty of entry, establishment, spread and impact are ☐ ☐ ⊠ provided in the document) Other recommendations: • Surveys are recommended to confirm the pest status • The EWG recommends research several following topics (see Q. 18) Content Stage 1.

Recent research and discussion on the efficacy of heat treatment against Agrilus planipennis . 66 3 Stage 1. Initiation Reason for performing the PRA: Agrilus planipennis Fairmaire, 1888 (Coleoptera: Buprestidae) originates from Far-East Asia and is primarily a pest of Fraxinus (ash). It was detected in North America (USA and Canada) in 2002 and in the European part of Russia (Moscow region) in 2005. It is a serious pest of Fraxinus where it has been introduced outside its native range. It has caused extensive ash mortality in North America and in the Moscow area and is spreading in all introduced areas. A. planipennis was added to EPPO A1 List of pests recommended for regulation in 2004, based on a PRA performed during the EPPO Panel on Quarantine Pests for Forestry in 2003. The short PRA report was finalized in 2004 (EPPO, 2004) to support this recommendation. A. planipennis was transferred to the A2 list in 2009, after its introduction and establishment in European Russia. When considering the measures recommended for Agrilus anxius, which has a similar biology and for which an EPPO PRA was performed in 2011 (EPPO, 2011), the Panel on Phytosanitary Measures noted that some measures were not consistent with those required against A. planipennis. The EPPO Working Party on Phytosanitary Regulation agreed in June 2012 that import measures for A. planipennis should be reviewed. At its meeting in October 2012, the Panel on Phytosanitary Measures decided that a more complete PRA should be prepared, especially to reconsider pest risk management in view of recent advances in A. planipennis research, and to obtain more information on spread, host plants, and the situation in Russia. The Secretariat decided to prepare this PRA according to the EPPO Standard PM 5/5 Express Pest Risk Analysis, to focus on available new information, and in particular to consider the current situation facing EPPO members, elements presenting a higher uncertainty and pest risk management.

Domain: Eukaryota; Kingdom: Metazoa; Phylum: Arthropoda; Class: Insecta; Order: Coleoptera; Family: Buprestidae; Genus: Agrilus; Species: planipennis Fairmaire, 1888. Synonyms. Jendek (1994) synonymized Agrilus feretrius Obenberger, 1936 (type Taiwan), Agrilus marcopoli Obenberger, 1930 (type China) and Agrilus marcopoli ulmi Kurosawa, 1956 (type Japan) with A. planipennis (type China) based on adult morphology. It is important to note that the host range of A. planipennis (and its former synonyms) varies from country to country. In North America and European Russia where it has been introduced, A. planipennis has only been reported to complete its life cycle on Fraxinus spp. Similarly, in China it has only been reported on Fraxinus (Yu, 1992; Liu et al., 2003) However, in Korea, Ulmus davidiana var. japonica is the only host listed by Ko (1969), while in Japan the reported hosts include Fraxinus mandshurica var. japonica, Juglans mandshurica, Pterocarya rhoifolia and Ulmus davidiana (Haack et al., 2002 citing others). The EWG did not find any host records for Agrilus planipennis (or A. feretrius) in Taiwan. One possible explanation for Juglans, Pterocarya and Ulmus species being reported as hosts of A. planipennis in Japan may be that
