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
In a review on Pierce’ disease (Xylella fastidiosa – EPPO A1 quarantine pest), it is noted that its efficient vector Homolodisca coagulata (Homoptera: Cicadellidae – EPPO Alert List) has been introduced into Tahiti, Polynésie française (Sforza ; Purcell, 2002). Present, no detail.

In a review paper by Oliveira et al. (2001), the presence of Bemisia tabaci (EPPO A2 quarantine pest) is mentioned in Bolivia and Montserrat. The EPPO Secretariat had previously no data on the occurrence of B. tabaci in these two countries. Present, no detail.

  • Detailed records
The ‘B’ biotype of Bemisia tabaci (EPPO quarantine pest) was first identified in Turkey in the autumn 2000. It was found in the eastern Mediterranean region near Adana and Içel on field vegetable crops. In this region, it is now a major pest of squash, bean, aubergine, Euphorbia pulcherrima, Hibiscus rosa-sinensis. By spring 2001, lower populations of B. tabaci biotype B were found on squash, melon, watermelon and cucumber but the pest has spread to all the eastern Mediterranean region (Ulusoy et al., 2002).

The ‘B’ biotype of Bemisia tabaci (EPPO quarantine pest) was found on samples of Lantana camara from Qalyubiya Governorate, Egypt (Abd-Rabou et al., 2001).

Clavibacter michiganensis subsp. michiganensis (EPPO A2 quarantine pest) was found in 2001, in six commercial fields (Lycopersicon esculentum cv. Target) in the eastern Anatolia region of Turkey. Although, it has been reported previously in Aegean and Mediterranean regions, this is the first report of the disease in the eastern Anatolia region. As only one cultivar was affected, it is suspected that contaminated seeds or transplants were the source of infection (Şahin, et al., 2002).

Severe outbreaks of Tomato spotted wilt tospovirus (EPPO A2 quarantine pest) are currently reported from Massachusetts, North Carolina and Virginia, US (Promed, 2002).

During winter 2000, Tomato yellow leaf curl begomovirus (EPPO A2 quarantine pest) was found for the first time in Islas Baleares, Spain. Both TYLCV-Is and TYLCV-Sar were detected in diseased tomatoes (Font et al., 2002).

  • New host plants
Arabis mosaic nepovirus (EU Annexes) was isolated for the first time on Choisya ternata (Rutaceae). Affected plants showed abnormal stunting, apical die-back of young shoots (Mumford et al., 2002).
