Résumé
Syrian citrus growing areas (Lattakia and Tartous) were firstly surveyed to assess citrus tristeza virus and the relative vectors. Eight nurseries, 2 budwood sources fields and 19 groves of the main citrus varieties were visually inspected and tested. A total of 89 CTV-infected plants out of 2653 samples were detected by DTBIA in 2 nurseries (13), 2 budwood sources fields (16) and 6 groves (60). Serological results were confirmed at IAMB. Based on the reactions with 9 MAbs and 2 Pabs, CTV sources were serologically included in 4 serogroups. Only one Valencia CTV-source induced severe symptoms on M. lime (vein clearing, leaf cupping, stunting and stem pitting). A. spiraecola (50%), followed by A. gossypii (27%) were the most common aphids, whereas no evidence of T. citricidus was found. This is the first report of CTV in Syria, but apparently, the virus is not spread by the vectors probably due to the presence of less efficient aphis spp.
