Kytodites nudus is a small cosmopolitan mite occasionally noticed as white spots on the bronchi, lungs, air sacs, and abdominal organs of chickens, turkeys, pheasants, pigeons, and mallards. (see Air Sac Mite.) These mites are readily transmissible between birds through coughing. They are rarely found in commercial industries. The 14- to 21-day life cycle involves a larval and 2 nymphal stages. Infestation densities vary, and clinical signs range from none to weakness, weight loss, pneumonia, peritonitis, pulmonary edema, and death. Recommended treatments include ivermectin, a nearby dichlorvos pest strip (placed out of reach of the birds), topical moxidectin, or a pyrethrin/piperonyl butoxide spray.
