A large survey was carried out on fruit flies in Australia in 1994. Among 17 species trapped, it was noted that Bactrocera tryoni (EPPO A1 quarantine) which occurs in the eastern states has spread to several locations in the Northern Territory. Review of Agricultural Entomology, 86(8), p 919 (7166).

In Iran, a survey was carried out in central Mazandaran (near the Caspian Sea) in 1996, to determine the possible spread of citrus tristeza closterovirus (EPPO A2 quarantine pest) from the initial infested foci (Mahdasht orchards in Sari). 400 samples were tested y DAS-ELISA , and 9 were found positive. All infected trees were Citrus unshiu grafted on Poncirus trifoliata and some were found in new sites in the province Mazandaran, in the suburbs of Babol (Note: it is a limited spread as Babol and Sari are rather close). Review of Plant Pathology, 77(7), p 794 (5922).
