New data on quarantine pests and pests of the EPPO Alert List
By browsing through the CABI Abstracts, 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
Beet necrotic yellow vein benyvirus (EPPO A2 list) occurs in Ukraine (Nurmukhammedov & Vasil’eva, 2003). Present, no details.
In Moldova, the first outbreaks of Erwinia amylovora (EPPO A2 list) were recorded in 1996 and 1997. Severe outbreaks were observed throughout the country and led to destruction of apple and pear orchards. Despite strict phytosanitary measures, local outbreaks of the disease have been reported consistently from numerous fruit-growing areas (Nicolaev et al., 2002). Present, no details.
Iris yellow spot virus (EPPO Alert List) was detected for the first time in Australia, infecting onions and leeks (Coutts et al., 2003). Present, no details.
Phytophthora fragariae (EPPO A2 list) was found for the first time in India, in October 2000 on strawberry plants growing in the region of Solan, Himachal Pradesh (Bhardwaj & Gupta, 2002). Present, found in 2000 in Himachal Pradesh.
In Belarus, strawberry mother plants grown at a research institute were tested by ELISA for the presence of viruses. The following viruses were detected: Arabis mosaic nepovirus (EU Annexes), Raspberry ringspot nepovirus (EPPO A2 list), Tomato black ring nepovirus (EU Annexes), Tomato ringspot nepovirus (EPPO A2 list) and Strawberry latent ringspot virus (EU Annexes). The EPPO Secretariat had previously no data on the occurrence of these viruses in Belarus (Semanas, 2002).
Stenocarpella macrospora (EPPO A2 list) occurs in maize crops in Uganda (Bigirwa et al., 2002). Present, no details.
Tomato yellow leaf curl begomovirus (EPPO A2 list) occurs in Nepal (Malla et al., 2002). Present, no details.
- Detailed records
In Mexico, Claviceps africana (EPPO Alert List) is spreading. It is now present in Coahuila, Colima, Nayarit, Nuevo Leon, Morelos and Sonora states (Velásquez-Valle et al., 2001).
In 2003, Erwinia amylovora (EPPO A2 list) was reported for the first time in Piemonte, Italy, on Cotoneaster (Gianetti et al., 2004).
Ralstonia solanacearum race 3 / biovar 2 (EPPO A2 list) was observed, in April 2002, in a commercial plantation of Pelargonium zonale in the state of Sao Paulo, Brazil (Almeida et al., 2003).
Tomato yellow leaf curl begomovirus (TYLCV - EPPO A2 list) occurs in Kyushu, Japan. The virus found showed 98 % similarity with TYLCV-Is (Onuki et al., 2004).
Xanthomonas vesicatoria (EPPO A2 list) is considered as one of the limiting factors for tomato and capsicum production in Sinaloa, Mexico (Carrillo-Fasio et al., 2001).
Xanthomonas vesicatoria (EPPO A2 list) occurs in Himachal Pradesh, India (Shukla et al., 2003).
- New host plants
During a study on viruses of forest trees done in Argentina, Tobacco ringspot nepovirus and Tomato ringspot nepovirus (both EPPO A2 list) were detected on Fraxinus americana (Dal Bó et al., 2003).
