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
Peach latent mosaic pelamoviroid (EU Annexes) is reported for the first time from Uruguay. PLMVd was detected in 2001 during a survey in 3 locations in the Canelones Department, the main peach-growing producing area (Promed posting, 2003). Present, found in Canelones Department.

Peach latent mosaic pelamoviroid (EU Annexes) is reported as present in Brazil, Nepal, Pakistan (Hadidi et al., 1997). Present no details.

Tomato ringspot nepovirus (EPPO A2 quarantine pest) was detected on soybean in Iran (Golnaraghi et al., 2002).

  • Detailed records
During surveys carried out in Yucatán, Mexico, phytoplasmas related to but distinct from Coconut lethal yellowing phytoplasma (EPPO A1 quarantine pest) were detected. Samples had been collected from coconut trees showing leaf yellowing in Oaxaca in 1997 and in Guerrero in 1998 (trees were then destroyed for precautionary reasons). Nutfall and inflorescence necrosis symptoms which usually precede foliar yellowing were atypically absent or delayed on these trees (Harrison et al., 2002).

Xanthomonas axonopodis pv. citri (EPPO A1 quarantine pest) was recently found in 3 new small areas in Florida (US), in the counties of Sarasota (first find in this county – in private gardens), Manatee (commercial citrus grove where infections had already been found in other parts of it) and Lee (private gardens). Eradication measures continue in Florida (DOACS Press Release, 2003).

  • New host plants
Tomato spotted wilt tospovirus (EPPO A2 quarantine pest) is reported from the first time in Liguria, Italy, on Euphorbia eritrea (found in 2000 on glasshouse-grown pot plants) and on Asclepias curassavica (found in 2002 on a few glasshouse-grown pot plants). Salomone et al., 2003.

  • Taxonomy
Considering morphological, molecular and serological characteristics, Potato latent virus (EPPO Alert list) is proposed as a new species in the genus Carlavirus (Brattey et al., 2002).
