Cucurbit chlorotic yellows virus, an emerging virus of cucurbits spreading worldwide
Cucurbit chlorotic yellows virus (Crinivirus, CCYV) is a virus transmitted by Bemisia tabaci (Hemiptera: Aleyrodidae – EPPO A2 List) which was first identified in Asia in 2004 and was causing damage to melon (Cucumis melo), watermelon (Citrullus lanatus) and cucumber (Cucumis sativus) crops in China, Japan, and Taiwan (EPPO RS 2011/007). It then spread to Africa (RS 2012/038), the Middle East (RS 2015/119) and has recently been reported from several countries in the EPPO region: Greece (Islands of Rhodos and Kriti) in 2014, Turkey in 2015, Israel in 2016, Algeria in 2018 (RS 2020/048), Spain in 2018 (RS 2021/166). It was also recently reported from the Islas Canarias (Spain) on watermelon and courgette (Cucurbita pepo) on Tenerife Island.
CCYV was first reported in the USA in 2018 in California, and in 2021 in Alabama, Florida, Georgia, Texas causing damage in fields of melon (Cucumis melo) watermelon and squash (Cucurbita pepo).
In Asia, it was further reported in 2021 from the Philippines (RS 2021/185), South Korea on melon (Cucumis melo and Cucumis melo var. makuwa) and on cucumber, and from India on pumpkin (Cucurbita moschata).
