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
Barley yellow dwarf luteovirus is reported for the first time from Tunisia. It was found in all surveyed regions: Beja, Bizerte, Cap-Bon, Jendouba, Le Kef, Siliana, Zaghouan (Makkouk et al., 2001). Present, in the major cereal-growing regions.
During a survey carried out in Lebanon in 1999, Beet necrotic yellow vein benyvirus (EPPO A2 quarantine pest) was detected in sugar beet samples collected in the Bekaa valley (Choueiri et al., 2000). Present, in the Bekaa valley (major sugar beet-growing region).
Diaporthe phaseolorum var. caulivora (Ascomycetes, Diaporthales), causing soybean stem canker, is reported for the first time from Argentina, at Oliveros, Santa Fe. In the fields where samples were collected, the disease incidence reached 76 % (Pioli et al., 2001). Present, found in 1999 near Santa Fe.
The Phytophthora root rot disease of alder (formerly on the EPPO Alert List) was first found in Italy. Seedlings of Alnus cordata growing in a nursery in northern Toscana were found naturally infected by the Phytophthora species. The disease caused wilting and mortality (Santini et al., 2001). Present, found in one nursery in northern Toscana.
Squash leaf curl begomovirus (EPPO A1 quarantine pest) is reported for the first time in Saudi Arabia (Al-Shahwan et al., 2000). Present, no details.
- Detailed records
Citrus tristeza closterovirus (EPPO A2 quarantine pest) is reported for the first time from the western area of Palestinian West Bank; it was not found in the eastern part of West Bank (Jarrar et al., 2000).
Ditylenchus dipsaci (EPPO A2 quarantine list) is reported from the Aegean region of Turkey on narcissus (Borazanci ; Çinarli, 1996), and from the Province of Amasya in the Black Sea region on onion, Allium cepa (Mennan ; Ecevit, 2001).
A recent survey on the distribution of potato cyst nematodes (EPPO A2 quarantine pests) in England and Wales (GB), showed that Globodera species were present in 64 % of sampled sited. Of the populations found, 67% were pure G. pallida, 8 % were pure G. rostochiensis and 25 % contained both species. These results showed an increase in potato cyst nematodes incidence and a shift towards G. pallida as the dominant species (Minnis et al., 2000).
Impatiens necrotic spot tospovirus (EPPO A2 quarantine pest) has been found in 1999 and 2000 on peanut (Arachis hypogaea) in Georgia, US (Wells et al., 2001).
In 1993-1994, Liriomyza trifolii (Diptera, Agromyzidae - EPPO A2 quarantine pest) caused damage to protected tomato crops in the Province of Içel, Mediterranean region of Turkey (Ulubilir et al., 1996).
Liriomyza trifolii (Diptera, Agromyzidae - EPPO A2 quarantine pest) is present in the Ismailia Governorate in Egypt (Omar ; Faris, 2000).
Meloidogyne chitwoodi (EPPO A2 quarantine pest) was first found in Texas (US) on potatoes in October 2000. The paper also mentioned its presence in New Mexico (Szalanski et al., 2001).
Mycosphaerella populorum (EPPO A1 quarantine pest) occurs in Kentucky, US. It was found in 2001-01, on two plantations of hybrid poplars ((Populus trichocarpa x P. deltoides) x P. maximowiczii) (Stanosz et al., 2001).
A study on tospoviruses in Greece, showed that Tomato spotted wilt tospovirus occurs in the prefectures of Drama, Pieria (near Katerini) and Xanthi. Impatiens necrotic spot tospovirus was not found (Chatzivassiliou et al., 2001).
In Iran, severe leaf and stem necrosis was observed in potato fields of Firuzkuh (Tehran Province) during summer 1998. Tomato spotted wilt tospovirus was detected in affected potato crops. This is the first report of this virus on potato in Iran, although its presence was reported from ornamental crops in the Tehran Province (near Tehran and Absard) (Pourrahim et al., 2001).
In 2000, Xanthomonas arboricola pv. pruni (EPPO A2 quarantine pest) has spread in Gard and Drôme (southeast of France), essentially on peach but also on apricot and plum (Breniaux, 2001).
Xanthomonas arboricola pv. pruni (EPPO A2 quarantine pest) occurs in the State of New York, US (Heidenreich et al., 2001)
Recent surveys showed that bacterial leaf scorch of northern red oak (Quercus rubra), caused by Xylella fastidiosa (EPPO A1 quarantine pest), is widespread in New Jersey, USA (USDA/Forest Service Pest Alert).
- New host plants
Spathiphyllum is reported as a new natural host of Impatiens necrotic spot tospovirus (EPPO A2 quarantine pest). Diseased plants were observed in a greenhouse in Toscana, Italy, in September 1999 (Materazzi ; Triolo, 2001).
