Summary

​​Whiteflies and whitefly-transmitted viruses are a major problem on watermelon and vegetable crops in the southeastern United States. Three whitefly-transmitted viruses—squash vein yellowing virus (SqVYV, which causes viral watermelon vine decline), cucurbit leaf crumple virus (CuLCrV), and cucurbit yellow stunting disorder virus (CYSDV)—are responsible for most of the losses reported in the Southeast. This presentation discusses both the progress made and the challenges that remain in management of whitefly-transmitted viruses: specifically, SqVYV on watermelon. Pest and disease managers will learn how insecticide treatments and reflective mulch affect disease development. Seed industry researchers will learn about breeding for resistance to whitefly-transmitted cucurbit viruses.
