First report of citrus tristeza virus in Tunisia
In Tunisia, following the observation of dieback symptoms in several orange (Citrus sinensis) orchards in the municipalities of Beni Khalled and Menzel Bouzelfa (Nabeul governorate), surveys were conducted by the NPPO. Laboratory analysis (serological and molecular tests) confirmed the presence of citrus tristeza virus (Closterovirus, CTV – EPPO A2 List). Phytosanitary measures are being implemented to eradicate the outbreaks and prevent any further spread. This is the first confirmed record of CTV in Tunisia. In the 1960s, infections had been reported on Meyer lemon (Citrus x meyeri), but these had subsequently been considered eradicated.
The pest status of citrus tristeza virus in Tunisia is officially declared as: Present, only in some areas, subject to official control.
