New data on quarantine pests and pests of the EPPO Alert List
By browsing 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 geographical records
In 1997/1998; a survey was carried out in hazel (Corylus avellana cv. Negret) orchards in Cataluña, Spain, for the presence of Apple mosaic ilarvirus (EPPO A2 quarantine pest on Rubus). It was detected in all tested hazel orchards (160 orchards). The EPPO Secretariat had previously no data on the presence of Apple mosaic ilarvirus in Spain (Aramburu ; Rovira, 2000). Present, at least in Cataluña.
In New Zealand, Meloidogyne fallax (EPPO A2 quarantine pest) occurs on potato in several sites on North Island (Anonymous, 2001a). Present, in North Island.
Peach latent mosaic pelamoviroid (formerly on the EPPO lists) is reported for the first time from Syria (Ismaeil et al., 2001). Present, in southern and central regions of Syria.
Its presence is confirmed in Lebanon (Choueiri et al., 2001). Present, no details.
The daisy rust (caused by Puccinia distincta or P. lagenophorae (taxonomy not resolved) - formerly on the EPPO Alert List) is reported for the first time from North America. It was observed in December 2000 in California, in USA (Koike ; Scholler, 2001). Present, in California.
- Detailed records
In 2000, the presence of Aleurocanthus woglumi (Homoptera: Aleyrodidae – EPPO A1 pest) was reported in Kwazulu-Natal (South Africa) and in Swaziland. A. spiniferus (EPPO A1 pest) was found in Mpumalanga and Northern Province (South Africa) and in Swaziland. Effective biological control with parasitoids (Encarsia smithi, Eretmocerus serius) was usually achieved in citrus orchards, but A. woglumi and A. spiniferus remain serious pests in areas where they spread without their parasitoids (Van den Berg ; Greenland, 2001).
In autumn 2000, foliar symptoms of stunting, curling and yellowing of the margins, and marked fruit size reduction were observed in some glasshouses of tomatoes in the Province of Bari, Puglia (south of Italy). The presence of Tomato yellow leaf curl Sardinia begomovirus was demonstrated by molecular assays. In mainland Italy, the virus had already been found in Calabria, but according to the authors this is now the first report in Puglia (Finetti Sialer et al., 2001).
It is reported that Ceratitis capitata (Diptera: Tephritidae - EPPO A2 quarantine pest) causes serious economic damage to apricot, citrus, fig, guava, mango and peach crops in Egypt, and that it is present in all Governorates (Saafan, 2000).
Tomato yellow leaf curl begomovirus (EPPO A2 quarantine pest) is reported for the first time from Mississippi (US). The virus was first found in Florida in 1997, and later in Louisiana in 2000. In January 2001, symptoms were observed in glasshouse tomatoes in east-central Mississippi and molecular assays confirmed the presence of the virus (Ingram ; Henn, 2001).
- New host plants
In Spain, Colletotrichum acutatum (EU Annexes) was observed for the first time on blueberry (Vaccinium corymbosum cv. Sharpblue) in 2 production fields in Huelva Province of Andalucía (Barrau et al., 2001)
Frankliniella occidentalis (Thysanoptera: Thripidae - EPPO A2 quarantine pest) is reported for the first time on barley (Hordeum vulgare) in New Zealand (Anonymous, 2001b).
Tomato spotted wilt tospovirus (EPPO A2 quarantine pest) was observed for the first time in 2000/2001 on Cichorium endivia crops in Basilicata, Italy (Grieco et al., 2001).
