Abstract
A field survey was conducted to determine the incidence of virus diseases affecting cucurbites in Syria, during 1999/2000 and 2000/2001 growing seasons. A total of 1689 plant samples with symptoms suggestive of virus infection were collected from 162 fields. Serological results showed that eight viruses naturally infecting cucurbites in Syria. Zucchini yellow mosaic virus (ZYMV) was the most commonly encountered virus in cucurbites fields, followed by Cucumber mosaic virus (CMV), Watermelon mosaic 2 virus (WMV-2), Zucchini yellow fleck virus (ZYMV), one virus of the family Luteoviridae, Squash mosaic virus (SqMV), Cucumber green mottle mosaic virus (CGMMV) and Melon necrotic spot virus (MNSV). The rate of infection in samples tested for the presence of one, two and three or more viruses were 16.8, 30.8 and 34.5%, respectively. The results showed that virus incidence was higher in the first season 1999/2000 than in the second season 2000/2001. The natural infection of cucurbit plants with some viruses was recorded for the first time in Syria.
