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
Liriomyza bryoniae (EU Annex I/A2) is present in China. Review of Agricultural Entomology, 86(3), p 256 (2070).
Opogona sacchari (EPPO A2 quarantine pest) was first found in China, in 1995-96. It was observed on Dracaena fragrans and also Euphorbia pulcherrima and Rhapis excelsa, in glasshouses in Beijing. Review of Agricultural Entomology, 86(3), p 358 (2876).
Detailed records
Bactrocera cucurbitae (EPPO A1 quarantine pest) occurs in Assam, India. Review of Agricultural Entomology, 86(3), p 325 (2626).
Bemisia tabaci (EPPO A2 quarantine pest) was found on Phaseolus vulgaris crops and associated weeds in the Provinces of Jujuy and Salta, Argentina. Review of Agricultural Entomology, 86(2), p 202 (1627).
Cherry leaf roll nepovirus (EPPO A2 quarantine pest on Rubus) occurs on birch trees in Germany. Review of Plant Pathology, 77(2), p 138 (1007).
In Belarus, it is estimated that Clavibacter michiganensis subsp. michiganensis (EPPO A2 quarantine pest), Xanthomonas vesicatoria (EPPO A2 quarantine pest), Pseudomonas syringae and Erwinia carotovora cause 20-30 % losses in protected tomatoes. Review of Plant Pathology, 77(3), p 305 (2239).
Colletotrichum acutatum (EU Annex II/A2) was found on strawberries in the suburbs of Shanghai in China. Review of Plant Pathology, 77(2), p 193 (1411).
Heavy infestations of Eutetranychus orientalis (EPPO A2 quarantine pest) have been recorded on Euonymus japonicus in Shandong, China, in 1995. Review of Agricultural Entomology, 86(3), p 352 (2837).
Liriomyza sativae (EPPO A1 quarantine pest) was first found in Hainan (China) in 1993, and it has then become a locally important pest of melons and vegetables. Review of Agricultural Entomology, 86(3), p 335 (2707).
Malacosoma disstria (EPPO A1 quarantine pest) occurs in British Columbia, Canada. Review of Agricultural Entomology, 86(2), p 229 (1841).
Phytophthora boehmeriae was isolated for the first time in Western Australia (Australia) from Eucalyptus sieberithora. Review of Plant Pathology, 77(2), p 130 (941).
In Venezuela, a survey was carried out in 1993 on Xylella fastidiosa (EPPO A1 quarantine pest) in vineyards of Zulia state, on 16 cultivars showing bacteria-like symptoms. X. fastidiosa was identified in 8 grape cultivars (French Colombard, Riesling, Early Muscat, Centennial seedless, Ruby seedless, Salt Creek, Alphonse Lavalle and Italia). Review of Plant Pathology, 77(3), p 315 (2315).
New potential vectors
A sensitive and specific assay (using PCR) for the detection of Xylella fastidiosa (EPPO A1 quarantine pest) was developed in USA. In a nursery where the disease occurs, 347 leafhoppers representing 16 species were captured on Ulmus americana. Two species regularly tested positive for X. fastidiosa: Graphocephala coccinea and G. versuta, and are considered as potential vectors of the disease. Review of Agricultural Entomology, 86(2), p 159 (1283).
