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
Chrysanthemum stunt pospiviroid (EPPO A2 quarantine pest) is reported for the first time on Dendranthema grandiflorum in the Republic of Korea. Diseased plants were collected from the main cultivation area of Masan, Kyongsang Namdo province (south of the country). Present, found in Kyongsang Namdo. Review of Plant Pathology, 81(4), p 496 (3570).

In 1996, Tomato yellow leaf curl begomovirus (EPPO A2 quarantine pest), was reported for the first time in Georgia on tomatoes. Present, no details. Review of Plant Pathology, 81(5), p 606 (4391).

  • Detailed records

In Papua New Guinea, Bactrocera papayae, was first observed in 1992 near the Indonesian border, and has then spread eastwards. It is now established on the mainland, in the highlands and the Central Province. Among other fruit flies of economic importance, B. neohumeralis and B. trivialis also occur in Papua New Guinea (the EPPO Secretariat had previously no data on these two species). Review of Agricultural Entomology, p 328 (2327).

From October 2000 to February 2001, a study on the distribution of Corythuca arcuata (EPPO Alert List), showed that it is present in an area of about 7000 km² in Lombardia and Piemonte. An isolated infested oak tree was also found on the northern coast ;of Lake Como, near the Swiss border. Review of Agricultural Entomology, p 564 (4189).

Eutetranychus orientalis (EU Annexes) occurs on citrus in Maharashtra, India. Review of Agricultural Entomology, p 540 (4010).

Mycosphaerella pini (EU Annexes) occurs in Heilongjiang, China. Review of Plant Pathology, p 4542 (4542).

Xanthomonas arboricola pv. pruni (EPPO A2 quarantine pest) occurs on plums in Basilicata, Italy, particularly on Japanese plums (Prunus salicina). Review of Plant Pathology, 81(4), p 456-457 (3524).

In 1999, the incidence of Xanthomonas axonopodis pv. citri (EPPO A1 quarantine pest) was studied in commercial groves in São Paulo and Minas Gerais, Brazil. Samples were collected and the highest disease incidence was found in the northwest zone of the studied region (4.3%), followed by the centre (0.5%) and north zone (0.2%), the disease was not observed in the south zone. Review of Plant Pathology, 81(5), p 593 (4298).

  • New host plants
Impatiens necrotic spot tospovirus (EPPO A2 quarantine pest) has been found on Oncidium varicosum (Orchidaceae). Leaves of infected orchids showed yellow mottling or streaks, irregularly shaped necrotic spots, and yellow to necrotic concentric ringspots. Review of Plant Pathology, p 617 (4470).

  • Taxonomy
Tomato yellow mosaic was first described in 1963 in Venezuela, as a geminivirus transmitted by Bemisia tabaci. In 1981 and 1985, it was reported to infect occasionally potato plants growing in the vicinity of tomato crops affected by this virus. Despite these previous reports, a virus isolated from potato plants showing a yellow mosaic in Venezuela was described in 1986 as a new geminivirus called Potato yellow mosaic begomovirus (EPPO Alert List). Comparative sequence analyses have recently shown that Potato yellow mosaic begomovirus is a synonym of Tomato yellow mosaic begomovirus.
