The whitefly-transmitted cucurbit yellow stunting disorder virus (CYSDV) infects cucurbits such as melons in several parts of the world. Infection can reduce crop yields. In 2006, CYSDV hurt cucurbit production in the low desert regions of California's Imperial, Coachella and Palo Verde valleys, Arizona's Yuma Valley and in nearby Sonora, Mexico. CYSDV infections were immediate and widespread among fall melon crops in 2006 and 2007 following heavy populations of the vector silverleaf whitefly. A cucurbit host-free period during the summer provided limited success in managing CYSDV, attributed mostly to fewer whiteflies in the Yuma Valley and central Arizona during July. Nearly all fall melon producers in Imperial County have chosen not to plant since 2007. Previous studies had shown that CYSDV was restricted to members of the Cucurbitaceae and lettuce as an experimental host, but we suspected other hosts were affecting the success of the cucurbit host-free period.
