New data on quarantine pests

By browsing through the literature, the EPPO Secretariat has extracted the following new data concerning quarantine pests.

New geographical records

Aphelenchoides besseyi (EPPO A2 quarantine pest) is reported for the first time in Turkey, in 1995, on rice plants and seeds grown in Ipsala (near Edirne) and Gönen (near Balikesir - both in Marmara region). Nematological abstracts, 67(4), p 222 (1847).

Cowpea mild mottle carlavirus (EU Annex I/A1) occurs in Jordan. It was isolated from aubergines (Solanum melongena) showing mild leaf mosaic (Mansour et al., 1998).

Potato spindle tuber viroid (PSTVd - EPPO A2 quarantine pest) occurs in Belarus. It is reported that PSTVd is widespread in Belarus and up to 30 % of the plants can be infected. Review of Plant Pathology, 78(1), p 62 (475).

Detailed records

Bemisia tabaci biotype B (also referred to as B. argentifolii - EPPO A2 quarantine pest) is newly reported to occur in: American Samoa, Fiji, Marshall islands, Niue, Northern Mariana islands, and French Polynesia (Tahiti). Review of Agricultural Entomology, 87(2), p 149 (1104).

Elsinoe fawcettii (EU Annex II/A1) occurs on citrus in Cheju island, Korea Republic. Review of Plant Pathology, 78(2), p 197 (1466).

Impatiens necrotic spot tospovirus (EPPO A2 quarantine pest) has been observed for the first time on cyclamen plants in Veneto, Italy. Review of Plant Pathology, 78(2), p 217 (1606).

Liriomyza sativae (EPPO A1 quarantine pest) occurs in Zhejiang province, China. The pest damages vegetable field crops (aubergines, Chinese cabbages, faba beans, lettuces, and melons). Review of Agricultural Entomology, 87(1), p 72 (550).

Phyllocnistis citrella occurs on citrus in Espirito Santo, Brazil. Review of Agricultural Entomology, 87(1), p 94 (707).

Phytophthora cinnamomi (EU Annex II/B) was found for the first time on avocado (Persea americana) in Italy, in spring 1998. Symptoms were observed in an experimental field near Rocca di Caprileone, in Sicily. Review of Plant Pathology, 78(2), p 198-199 (1476).

Scirtothrips dorsalis (EPPO A1 quarantine pest) occurs in Rajasthan, India. Review of Agricultural Entomology, 87(2), p 201 (1490).

New data on grapevine yellows

Molecular studies (RFLP analysis of PCR-amplified 16S rDNA) showed that Virginia grapevine yellows phytoplasma is distinct from all other phytoplasmas studied. There was no evidence of grapevine flavescence dorée (EPPO A2 quarantine pest), bois noir or Australian grapevine yellows phytoplasmas in Virginia (US). Review of Plant Pathology, 78(2), p 194 (1445).

Surveys were carried out during 1995 in 5 German vineyards to determine the host plants of Hyalesthes obsoletus (vector of Vergilbungskrankheit, VK - grapevine yellows). Hosts plants were Convolvulus arvensis, Urtica dioica, Artemisia vulgaris, Senecio erucifolius, Ranunculus bulbosus and Solanum nigrum. Vineyards with a high abundance of C. arvensis showed a high level of infection (30-34 %) of H. obsoletus by VK. Review of Plant Pathology, 78(2), p 194 (1447).
