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
Arceuthobium minutissimum (EPPO A1 List - Himalayan dwarf mistletoe) occurs in Bhutan. In Western Bhutan, it is widespread and very damaging to dry forests of Pinus wallichiana (blue pine) in the districts of Paro, Ha and Thimphu. Infected trees show deformations, stunted growth, witches’ brooms, reduced cone production, and mortality (Dorji et al., 2012). Present, widespread in Western Bhutan.
Bemisia tabaci (Hemiptera: Aleyrodidae – EPPO A2 List) occurs in Bosnia and Herzegovina and Montenegro. In Bosnia-Herzegovina, it was first found in 2008 in both glasshouse and outdoor crops. Present, in protected and outdoor crops.
In Montenegro, it was found for the first time in 2008 on ornamental plants in a greenhouse near Podgorica. Surveys carried out from 2008 to 2011 detected the pest in several glasshouses (ornamental plants) in Podgorica, Bar, Ulcinj and Radanovici (near Tivat). In autumn 2011, B. tabaci was found once on an outdoor melon crop near Ulcinj (Hrnčić et al., 2012). Present, mainly in protected crops.
Cydalima perspectalis (Lepidoptera: Crambidae – formerly EPPO Alert List) is recorded for the first time from Croatia. In June 2012, 2 specimens were caught in a light trap in the northern part of Istria, on Parenzana road between the villages of Valica and Sveta Marija na Krasu, close to the Slovenian border (Koren ; Črne, 2012).
Glycaspis brimblecombei (Hemiptera: Psyllidae – formerly EPPO Alert List) was detected for the first time in 2011 in the Gharb region, in Morocco. Two outbreaks were found on eucalyptus forests in the province of El Kelaa des Sraghna (Ibnelazyz, 2011).
In Montenegro, the presence of Peach latent mosaic viroid was detected for the first time during a survey carried out in 2007. The viroid was detected in peach trees (Prunus persica cv. ‘Elegant Lady’) in the area of Ćemovsko, a region where approximately 40% of the peach production is located (Mavrič Pleško et al., 2012).
In Norway, Pseudomonas syringae pv. aesculi (EPPO Alert List) causing bleeding cankers on horse chestnut (Aesculus hippocastanum) was detected for the first time in June 2010 in the south western part (Talgø et al., 2012).
Plum pox virus (Potyvirus, PPV – EPPO A2 List) occurs in Belarus. It was first identified in 2000 in the Minsk region on symptomatic plum trees (Prunus domestica cv. ‘Nagrada Namanskaja’). Surveys conducted in 2011 showed that PPV was detected in 32% of the symptomatic samples collected from stone fruit orchards in the regions of Vitebsk, Grodno and Mogilev (Salavei et al., 2012).
- Detailed records
In the USA, a recent review concerning Agrilus anxius (Coleoptera: Buprestidae – EPPO A1 List) indicates that it also occurs in Arizona, North Carolina and Rhode Island (Muilenburg ; Herms, 2012).
- Epidemiology
Studies have recently shown that Frankliniella fusca can transmit Iris yellow spot virus (Tospovirus, IYSV – formerly EPPO Alert List) but with a lower efficiency than Thrips tabaci (Srinivasan et al., 2012).
- Taxonomy
The fruit fly species Trirhithromyia cyanescens (Diptera: Tephritidae – EU Annexes) has now been transferred into the genus Neoceratitis, and thus should now be called Neoceratitis cyanescens (de Meyer ; Freidberg, 2012).
