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.  To obtain a free pesticide guide for cherry fruit fly and other tree fruit pests, contact the Wasco County Extension Office at 541-296-5494.
