First report of cucurbit yellow stunting disorder crinivirus in USA (Texas) and Mexico


In late summer 1999, severe symptoms of yellowing and stunting were observed on field and glasshouse-grown melons (Cucumis melo) near Donna in southern Texas (US) and near Reynosa in northern Mexico. High populations of Bemisia tabaci (EPPO A2 quarantine pest) were associated with infected crops. Molecular analysis showed that symptomatic melon plants from both areas were infected by cucurbit yellow stunting disorder crinivirus (EPPO Alert List). This is the first report of this virus in North America.
