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 on the EPPO Alert List. The situation of the pest concerned is indicated in bold, using the terms of ISPM no. 8.

  • New records

Euphorbia mosaic virus (Begomovirus - EU Annexes) has been detected in the Yucatan peninsula, Mexico (Hernández-Zepeda et al., 2007). Present, in the Yucatan peninsula.

Scaphoideus titanus (Hemiptera: Cicadellidae) occurs in the south of Bosnia and Herzegovina (Delić et al., 2007). Present, in the south of the country.

  • Detailed records

In Portugal, Cryphonectria parasitica (EPPO A2 List) was first observed in 1929 on bark samples collected from branches of Castanea crenata in the Beira Interior Province. These initial infections were probably eradicated, as no further reports were made until 1989 when two outbreaks were found on C. sativa in the Trás-os-Montes province (which is the main chestnut-growing area in Portugal). In recent surveys, C. parasitica was detected across four mainland provinces (Minho, Trás-os-Montes, Beira Interior, Alentejo), Azores (Pico, San Miguel, Terceira) and Madeira (Bragança et al., 2007).

In Belarus, Ditylenchus destructor (EU Annexes) is unevenly distributed and occurs mainly in the region of Minsk (Ilyashenka ; Ivaniuk, 2008).

Heterodera glycines (EPPO A2 List) occurs in the state of Maranhão, Brazil (Cunha et al., 2008).

A survey carried out in Northern Iran showed that Heterodera glycines (EPPO A2 List) occurs in Mazandaran and Golestan provinces, the main soybean-producing areas of the country (Maafi et al., 2008).

In Spain, Monilinia fructicola (EPPO A2 List) was first reported in 2006 on peach trees (Prunus persica) in two adjacent localities: Ivars de Noguera (Provincia de Lleida, Cataluña) and Castillonroy (Provincia de Huesca, Aragón). In March 2006, M. fructicola was also found in mummified peach fruits (P. persica cv. ‘Autumn Free’) in orchards located at Sudanell (Provincia de Lleida, Cataluña), approximately 30 km south of the initial findings (De Cal et al., 2009).

In Argentina, Nacobbus aberrans (EPPO A1 List) was detected on potatoes in Jujuy province during surveys carried out in 2003 and 2004 (Muruaga de l’Argentier et al., 2007).

Meloidogyne fallax (EPPO A2 List) was detected for the first time in Victoria, Australia. The nematode was detected on potatoes (Nambiar et al., 2008).

Mycosphaerella pini (EU Annexes) has become frequent in recent years on Pinus nigra and Pinus mugo in the continental part of Slovenia (Jurc, 2007).

Potato spindle tuber viroid (Pospiviroid – EPPO A2 List) was found in several potato cultivars in Primor’e (Far East of Russia). PSTVd was detected in combination with Potato virus Y (Romanova et al., 2007).

Xanthomonas oryzae pv. oryzae (EPPO A1 List) occurs in Rajasthan, India (Nayak et al., 2009).

In summer 2004, bacterial leaf scorch caused by Xylella fastidiosa (EPPO A1 List) was first found in Oklahoma (US) in Ulmus americanus. Additional infections were then reported on other tree species (e.g. Quercus spp., Morus spp., Platanus occidentalis). In July 2008, the bacterium was detected on Vitis labrusca cv. ‘Concord’ showing symptoms of Pierce’s disease. This is the first time that Pierce’s disease is reported from Oklahoma (Smith et al., 2009).

  • Taxonomy

Ascochyta pisi is one of the causal agent of Ascochyta blight of pea (Pisum sativum). The teleomorph of A. pisi has recently been obtained in laboratory conditions and called Didymella pisi sp. nov. (Chilvers et al., 2009).

A new nematode species, Bursaphelenchus macromucronatus sp.nov. has recently been described. It was isolated from Taiwanese and Indian packaging wood (Gu et al., 2008). Its separation from other species of the ‘xylophilus’ group is mainly based on female tail shape, spicules size and the mucro length. B. macromucronatus can be differentiated from B. xylophilus, B. mucronatus, B. fraudulentus, B. conicaudatus, B. luxunosae, B. doui and B. singaporensis by molecular tests (RFLP, sequencing of the ITS region).
