Abstract
X-disease is a widespread plant disease critically impacting cherries and other stone fruit (genus Prunus) in the United States’ Pacific Northwest region. First identified in Washington State in 1946, X-disease’s prevalence has dramatically increased in Washington over the last decade. X-disease is caused by the phytoplasma Candidatus Phytoplasma pruni, which infects the phloem of cherry trees and causes fruit to be small, bitter, and unmarketable. Leafhoppers (Hemiptera: Cicadellidae) are the only known vector of X-disease phytoplasma. It is important to monitor for the presence of X-disease vector leafhoppers in cherry and stone fruit orchards to determine appropriate management strategies. Three common leafhopper sampling methods include sticky traps, sweep nets, and vacuum tools like a modified leaf vacuum or Dietrick Vacuum Sampler (DVAC). This publication describes each sampling method, along with previous research, techniques, advantages, and disadvantages, to improve decision-making.
