Summary: The first detection of spotted wing drosophila in eastern Washington caused a sudden shift in the insect management programs of sweet cherry growers in the region. While populations and damage levels have varied from year to year, this pest continues to be a challenge to cherry growers. Early research focused on assessment of chemical control options, and the cherry industry has picked 2-3 materials that give consistent results. Unfortunately, several are in the same chemical class, spinosyns, and warning were issued about the possibility of resistance. A previous project set baselines for some of the primary active ingredients, and can be used to track incipient resistance in the future. In the meantime, new techniques and approaches are needed to address the single-tactic approach to control.
