Subject: Cucumber vein yellowing virus (CVYV) reported from Spain
Date posted: December 05, 2001

In autumn 2000 and spring 2001, CVYV was found affecting cucumber and watermelon crops, respectively, in the Poniente area of Almeria, Spain. CVYC was previously only known from Israel (where it was first described), Jordan, Turkey, and Sudan; it is probably also found in Syria and Saudi Arabia. This potyvirus is transmitted mechanically and through grafting, and is vectored by the sweetpotato whitefly, Bemisia tabaci. This whitefly is a serious pest of cultivated crops in Hawaii, and has been reported from North America in the U.S.A. (Arizona, California, Florida, Georgia, Maryland, Texas) and Mexico. Potential pathways for CVYV spread include Cucurbitaceae vegetative material, viruliferous B. tabaci, and possibly cucurbit fruit.
