New data on quarantine pests and pests of the EPPO Alert List
By searching through the literature, the EPPO Secretariat has extracted the following new data concerning quarantine pests and pests included (or formerly included) on the EPPO Alert List, and indicated in bold the situation of the pest concerned using the terms of ISPM no. 8.
- New records
In Bosnia and Herzegovina, Aproceros leucopoda (Hymenoptera: Argidae – formerly EPPO Alert List) was first found in 2017 in the municipality of Vareš on Ulmus glabra (Dautbašić et al., 2018).
In France, Aproceros leucopoda (Hymenoptera: Argidae – formerly EPPO Alert List) was first found in May 2017 in the Nord department, in the forest of Cassel. It was then also observed in Villers-Saint-Paul (near Creil - Oise department), and in Cergy (Val d’Oise department) (Internet, 2018).
In the United Kingdom, Aproceros leucopoda (Hymenoptera: Argidae – formerly EPPO Alert List) was first found in May 2017 as part of local plant recording activity carried out by experienced amateurs in Surrey (near Dorking) in autumn 2017. In June 2018, further reports have come in from across a wide area of south east England and the east Midlands (Internet, 2018).
In China, Heterodera elachista (EPPO Alert List) was recently found in a soil sample taken from a rice field in Jiangxi. The authors also mentioned its presence in Hubei (Feng et al., 2018).
In China, Heterodera glycines (EPPO A2 List) is reported in Beijing, Shanghai, Sichuan and Yunnan. The authors noted that the soybean cyst nematode was first discovered in Heilongjiang Province in 1899 and is now reported from 23 provinces in China (Feng et al., 2018).
Huanglongbing (associated with ‘Candidatus Liberibacter spp.’ – EPPO A1 List) occurs in Guatemala. It was first found in 2010 in the municipalities of Poptún, Dolores, Sayaxché, San José, San Luis and Melchor de Mencos (Petén department); Livingston and Puerto Barrios (Izabal department); Fray Bartolomé de las Casas (Alta Verapaz department). Under official control (Internet, 2018). Present, only in some areas, under official control.
In Morocco, Pezothrips kellyanus (Thysanoptera: Thripidae – formerly EPPO Alert List) was first found in 2008 in the region of Beni-Mellal, and a year later in the region of Souss-Massa. It was initially considered to be a minor pest, but severe outbreaks were reported in 2018 in the Souss-Massa region in citrus crops (Smaili et al., 2018).
In Tunisia, Pezothrips kellyanus (Thysanoptera: Thripidae – formerly EPPO Alert List) was first found in 2008. It was initially considered to be a secondary pest, but its distribution and damage have increased during the last decade. It is now common in citrus-growing areas of Tunisia (Bizerte, Mornag and Cap-Bon) (Gelaam Kort and Boulahia-Kheder, 2017).
The presence of Potato mop-top virus (Pomovirus, PMTV) is reported for the first time in 2018 from New Zealand. PMTV has been detected on potato tubers from 2 properties in the Canterbury region (South Island). Biosecurity New Zealand is investigating how the virus may have entered the country (Biosecurity New Zealand, 2018).

Agrilus planipennis (Coleoptera: Buprestidae – EPPO A2 List) occurs in South Dakota (US). Regulated areas have been delimited in the counties of Lincoln, Minnehaha, and Turner. A. planipennis also occurs in Vermont. Official control measures are being taken to prevent further spread of the pest (NAPPO, 2018).
The pest status of Agrilus planipennis in the USA is officially declared as: Present in some parts of the United States and subject to official control to prevent further spread.
In the United Kingdom, Phytophthora foliorum was detected for the first time March 2016, in a single Rhododendron ponticum plant in Scotland (EPPO RS 2016/059). The infected plant was destroyed, and subsequent delimiting surveys have led to no further findings. Therefore, the NPPO of the United Kingdom now considers that this outbreak has been eradicated (NPPO of the United Kingdom, 2018).
In Italy, Tomato ringspot virus (Nepovirus, ToRSV - EPPO A2 List) was detected in Emilia-Romagna in pomegranate trees (Punica granatum) which had been imported from the USA (EPPO RS 2015/194). Since 2015, all plants belonging to the infected lot have been destroyed and specific surveys have been carried out. After two years of investigations, no other cases of ToRSV have been found. Therefore, the NPPO of Italy concluded that ToRSV has been successfully eradicated (NPPO of Italy, 2018).
- New pests and taxonomy
Stagonosporopsis andigena (=Phoma andigena – EPPO A1 List) causes a leaf spot disease on tomato (Solanum lycopersicum) and potato (S. tuberosum) in Bolivia and Peru, at altitudes between 2000 and 3500 m. In the 1980s, a variant called Phoma andina var. crystalliniformis was identified on tomato and potato samples collected in Colombia and Venezuela at altitudes between 1500 and 3700 m (Loerakker et al., 1986). More recent studies (Aveskamp et al., 2010) concluded that Phoma andina var. crystalliniformis should be considered as a separate species, Stagonosporopsis crystalliniformis. Revised geographical distributions for both S. andigena and S. crystalliniformis can be consulted in the EPPO Global Database.
In EPPO RS 2018/181: Dothistroma septosporum was found in Thiessow (Mecklenburg-Western Pomerania) and not in ‘Thuringia’.
In EPPO RS 2018/138: the title of the article mentioned a first outbreak of Anoplophora chinensis in France (in Royans, Charente-Maritime department). However, the first record of A. chinensis in France was made in 2003 in Soyons (Ardèche department) and this first outbreak was then successfully eradicated.
