Euscelidius variegates is the dominating cherry X-disease vector in The Dalles, Oregon and has caused substantial economic loss in cherry industry. Mark-release-recapture (MRR) experiments were conducted to understand the movement and dispersal of E. variegatus in management cherry orchards. Adult leafhoppers were sourced from cherry orchards using reversed leaf blowers, marked with Day-glow fluorescent powder, and released at multiple distances from a central sticky trap in two orchard sites. The marking method has no significant affect on the survival rate of E. variegates. In total, six MRR experiments were performed within a 4-meter range and the overall release-recapture rate was 1.25%. The peak recapture rate occurred at 1 meter from the central trap, then diminishing sharply at greater distances. The maximum dispersal distance of the marked E. variegatus was estimated to range from 6 to 11 meters. The ground cover conditions in the drive rows could have potential influence on leafhopper movements. This research enhanced the understanding of E. variegate movement patterns in the Oregon cherry orchards and informs the development of targeted disease management and integrated pest management (IPM) strategies in Oregon’s cherry orchards.
