      Pinyon needle scale (Matsucoccus acalyptus) are very small (0.5 mm) sucking insects that feed on pinyon, singleleaf pinyon, and foxtail pines in the southwestern United States. These insects can be effectively controlled using an integrated approach which includes sanitation, supplemental irrigation, and pesticides.
