New geographical records
During a survey carried out in 1994/1995, impatiens necrotic spot tospovirus was found for the first time in Poland. The virus was detected on Schefflera actinophylla grown in commercial glasshouses. Review of Plant Pathology, 76(7), p 760 (5899).
Lopholeucaspis japonica (EPPO A2 quarantine pest) was found in Uttar Pradesh, in India. According to the authors, this is the first report of L. japonica in India. However, there had been earlier records which were not confirmed at the time by the Indian authorities. Review of Agricultural Entomology, 85(5), p 620 (4775).

The occurrrence of Bemisia tabaci biotype B (B. argentifolii – EPPO A2 quarantine pest) is confirmed in Egypt. Review of Agricultural Entomology, 85(6), p 751 (5806).
Carposina niponensis (EPPO A1 quarantine pest) is a common pest of fruit trees in the Jilin Province, China. Review of Agricultural Entomology, 85(7), p 858 (6680).
Chrysanthemum stunt viroid (EPPO A2 quarantine pest) was detected in glasshouse chrysanthemum in Queensland, Australia. Review of Plant Pathology, 76(6), p 648 (5047).
Dryocoetes confusus (EPPO A1 quarantine pest) is present in Utah, USA, and can cause serious damage to drought-stressed Abies lasiocarpa. Review of Agricultural Entomology, 85(9), p 1126 (8896).
Erwinia amylovora (EPPO A2 quarantine pest) was observed for the first time in Macedonia in 1986 (see EPPO RS 96/145) in a quince orchard near the Greek border and in a pear orchard near Radovish. During the following 3 years, the disease spread and in 1991, more than 400 ha of pear orchards and more than 60 ha of quince orchards were destroyed.

Helicoverpa zea (EPPO A1 quarantine pest) larvae were collected from cotton fields in the State of Tamaulipas, Mexico, during 1990-95. Review of Agricultural Entomology, 85(6), p 740 (5716).
Surveys were carried out in Pakistan during 1986-87 and 1991-92, to evaluate the incidence of Tilletia indica (EPPO A1 quarantine pest). A total of 2274 wheat samples were tested (dry inspection method), and 58.53 % of them were found infested. The highest percentage of infection was found in Central Punjab (7.66 %) and the Northwest area of Pakistan (8.72 %). Review of Plant Pathology, 76(6), p 582 (4503).
