New data on pests of quarantine importance
By browsing through the literature, the EPPO Secretariat has extracted the following new data concerning pests of quarantine importance.
New geographical records
Apple mosaic ilarvirus (EPPO A2 quarantine pest on Rubus) is present on fruit trees in Greece, Turkey and Uruguay. Review of Plant Pathology, 76(1), p 64-65-79 (503-505-601).
Cherry leaf roll nepovirus (EPPO A2 quarantine pest on Rubus) was obtained from a wide range of naturally infected plants in Hungary (e.g. Juglans regia, Sambucus nigra). Review of Plant Pathology, 76(1), p 21 (160).
Monilinia fructicola (EPPO A1 quarantine pest) is present in Korea Republic (Gyeonbuk province). Review of Plant Pathology, 76(1), p 80 (607).
Significant yield losses due to Phialophora gregata (EPPO A1 quarantine pest) are reported from Brazil (Rio Grande do Sul, Santa Catarina) on soybean crops. Review of Plant Pathology, 76(1), p 41 (321).
Detailed records
Bemisia tabaci biotype B (EPPO A2 quarantine pest) is present in Federal District of Brazilia (Brazil) on vegetable crops. Review of Agricultural Entomology, 85(2), p 149 (1188).
Bursaphelenchus xylophilus (EPPO A1 quarantine pest) is present in the Anhui province in China. Nematological Abstracts, 65(4), 84(12), pp 184-185-226 (1481-1489-1866).
Bursaphelenchus xylophilus (EPPO A1 quarantine pest) was found in China, on dying Pinus thunbergii trees in Shanghai Sheshan Mountain (Shanghai Municipality) during a survey in 1989-1991. Nematological Abstracts, 65(4), 84(12), 225-226 (1859).
Ceratitis capitata (EPPO A2 quarantine pest) is present in Rio de Janeiro, Brazil. Review of Agricultural Entomology, 85(2), p 144 (1144).
Diabrotica virgifera (EPPO A2 quarantine pest) has recently become a serious maize pest in New York state (US). Agricultural Entomology, 85(2), p 189 (1474).
Grapevine flavescence dorée phytoplasma (EPPO A2 quarantine pest) is reported, together with bois noir phytoplasma in the region of Treviso (Veneto), in Italy. Review of Plant Pathology, 76(1), p 85 (644-647).
In Turkey, during surveys carried out on virus diseases of vegetables in Izmir (1992) and in Mugla (1993-1994), tomato ringspot nepovirus (EPPO A2 quarantine pest) and tomato black ring nepovirus (EU Annex II/A2) were detected by ELISA. Tomato ringspot nepovirus was found on tomato and capsicum in the region of Izmir, and on cucumbers in Mugla. Tomato black ring nepovirus was found on tomato in Izmir and on aubergines in Mugla. This confirms the occurrence of the two viruses in the Aegean region of Turkey (EPPO RS 94/202). Review of Plant Pathology, 76(1), p 55 (428).
Spodoptera litura (EPPO A1 quarantine pest) was trapped in Henan province in China. Review of Agricultural Entomology, p 168 (1325).
New host plants
In China, two populations of Heterodera glycines (EPPO A1 quarantine pest) were collected from Paulownia sp. in Henan province in 1986 and from Pisum sativum in Inner Mongolia Autonomous region in 1984 (this is also a new detailed record for China). Both populations were able to infect soybean plants. Paulownia and Pisum sativum are reported as hosts for the first time. Nematological Abstracts, 65(4), p 200-201 (1634).
