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
Beet necrotic yellow vein benyvirus (rhizomania - EPPO A2 quarantine pest) occurs in Iran (Farzdfar et al., 2002).
A study was done in Colombia to determine the main potato viruses in the departments of Caldas and Tolima. Serological tests revealed high incidences and concentrations of Andean potato latent tymovirus and Andean potato mottle comovirus (both EPPO A1 quarantine pests). The EPPO Secretariat had previously no data on the occurrence of Andean potato mottle comovirus in Colombia. Present, found in Caldas and Tolima departments. Review of Plant Pathology, 80(9), p 879 (6240).
In an annual report on migratory Lepidoptera in the Netherlands, it is noted that Cacyreus marshalli (Lepidoptera: Lycaenidae - EPPO A2 quarantine pest) has been observed in 1999 in the Netherlands. However, this species is not considered as established. Transient. Review of Agricultural Entomology, 89(10), p1297 (9282).
Diaphorina citri (Hemiptera: Psyllidae - EPPO A1 quarantine pest) is reported for the first time in the Peninsula de Paraguaná, State of Falcón, in Venezuela. It was observed in April 1999 on Citrus aurantifolia and later on C. reticulata, C. latifolia and Murraya paniculata. Present, found in 1999 in the state of Falcón. Review of Agricultural Entomology, 89(9), p 1013 ( 7304).
Liriomyza huidobrensis (Diptera: Agromyzidae – EPPO A2 quarantine pest) was found for the first time in Taiwan in early 1999, and spread to many vegetable crops. Present, widespread. Review of Agricultural Entomology, 89(9), p 1117 (8040).
- Detailed records
High infestations of Bemisia tabaci biotype B (Homoptera: Aleyrodidae - EPPO A2 quarantine pest) were observed in a large soybean field in the State of Maranhão, Brazil, in 1999. Review of Agricultural Entomology, 89(12), p 1482 (10558).
In New Zealand, a survey done in 1997 showed that Ciborinia camelliae (Ascomycota: Leotiales - EPPO A2 quarantine pest) was widely distributed in western, central and lower North Island. In 1998, it was found that the disease had not spread in North Island, except for an isolated outbreak in Auckland. In South Island, C. camelliae was only found in Picton, Nelson, Golden Bay, Blenheim, Kaiapoi and Christchurch. Review of Plant Pathology, 80(12), p 1284 (9009 ; 9010).
Frankliniella occidentalis (Thysanoptera: Thripidae – EPPO A2 quarantine pest) occurs on glasshouse crops in Wakayama Prefecture, Honshu, Japan. Review of Agricultural Entomology, 89(9), p 1163 (8353).
Liriomyza trifolii (Diptera: Agromyzidae – EPPO A2 quarantine pest) occurs in Sohag governorate, Egypt. Review of Agricultural Entomology, 90(2), p 101 (665).
Tomato spotted wilt tospovirus (EPPO A2 quarantine pest) occurs in Assam, India, and causes problems on Capsicum annuum crops. Review of Plant Pathology, 80(9), p 904 (6399).
Wheat High Plains virus (EPPO Alert List) occurs in Kansas and Utah, USA (Seifers et al., 2002)
- New host plants
In Toscana, Italy, Impatiens necrotic spot tospovirus (EPPO A2 quarantine pest) was found for the first time on Spathiphyllum plants grown under glass. Review of Plant Pathology, 80(9), p 920 (6505).
