A field survey was conducted during 1999/2000 and 2000/2001 growing seasons to determine the incidence of virus diseases affecting cucurbit crops in Syria.

A total of 1689 plant samples with symptoms suggestive of virus infection were collected from 162 fields in Aleppo, Edleb, Hama, Homs, Latakia and Tartous provinces.

Serological tests indicated the presence of eight cucurbit viruses; Zucchini yellow mosaic virus (ZYMV) was the most commonly encountered virus in cucurbit fields, followed by Cucumber mosaic virus (CMV), Watermelon mosaic virus-2 (WMV-2), Zucchini yellow fleck virus (ZYMV), Squash mosaic virus (SqMV), Cucumber green mottle mosaic virus (CGMMV), Melon necrotic spot virus (MNSV), and possibly one or more unidentified luteoviruses.

Virus incidence in tested samples infected with only one virus, two viruses and three or more viruses were 16.8%, 30.8% and 34.5%, respectively.

Virus incidence was higher in the first season 1999/2000 in comparison with the second season 2000/2001.

This is the first record of natural infection of cucurbit plants with ZYMV, CGMMV, MNSV and SqMV in Syria.
