Survey on Citrus tristeza closterovirus in Cyprus

A programme to control Citrus tristeza closterovirus (CTV - EPPO A2 quarantine pest) in Cyprus was initiated in 1992. In particular, it includes a survey of all citrus groves to determine virus incidence in the 5 citrus-growing districts of Cyprus. In each citrus grove, 10-20 % of the trees were tested (ELISA). So far, a total of 601 citrus groves (212,200 trees) have been surveyed. CTV was detected in 152 groves (25.3%) and in 2,483 trees out of the 50,750 tested trees (4.9%). The highest proportion of infected trees (18.3%) and groves (71%) was found in the district of Ammochostos, where eradication of the disease is no longer considered feasible. In other districts (Nicosia, Limassol, Larnaca and Paphos), all infected trees, including seven entire groves, have been destroyed with compensation for the growers. The situation of CTV in Cyprus can be described as follows: Present, eradication is no longer envisaged in Ammochostos district but continues in Nicosia, Limassol, Larnaca and Paphos districts.
