The cherry fruit fly emerged in The Dalles area on Wednesday. That’s according to Oregon State University Wasco County Extension Horticulturist Lynn Long. The entire cherry-growing area, including The Dalles, Mosier, and Dufur, are within a cherry fruit fly control district. All homeowners with a backyard tree as well as commercial orchardists are required by state ordinance to apply a control program. Long says for homeowners the recommended materials would include Spinosad or Malathion.
