ABSTRACT

A survey of Tomato spotted wilt virus (TSWV, Tospovirus, Bunyaviridae) and Tomato yellow leaf curl virus (TYLCV, Begomovirus, Geminiviridae) infection in some important crops in the Syrian coastal region was made. Samples showing leaf curl and yellowing symptoms were collected from 19 regions during the 2017 and 2018 growing seasons (311 mixed samples and 1244 individual samples). Triple antibody sandwich ELISA (TAS–ELISA) was used to detect TYLCV, whereas tissue blot immunobinding assay (TBIA) was used to detect TSWV. The results of TAS–ELISA and TBIA showed the presence of the two viruses in all visited regions, causing single or mixed infections (26.04% and 32.79% assingle infections by TSWV and TYLCV, respectively, and 14.14% as mixed infection). The highest rate of TSWV infection was 50% in Setkheres region, and that of TYLCV infection was 54.54% in Yahmour region. The infection rate of TSWV in tobacco was 47.45%, and that ofTYLCV in pepper was 51.31%, whereas the rate of mixed infection in tomato was 25.45%. This is the first report of TSWV infection in grapevine (6.66%) and Ocimumbasilicum (16.66%) and of TYLCV infection in Phaseolus vulgaris (27.02%) in Syria.
