The European Corn Borer (Ostrinia nubilalis) is a pest of corn and its presence can affect interstate trade of that commodity. Surveys are conducted because of the presence of potential host material in Wyoming and potential introductions pathways from surrounding states. It is established in the eastern and central US. It has been found in three Wyoming counties in survey activities related to the Wyoming Pest Detection / CAPS Program . Fifty-eight total traps have been placed throughout twenty-two counties in Wyoming.
Wyoming European Corn Borer Survey is conducted by the Wyoming Pest Detection /
CAPS Program. A sticky trap with pheromone attractant is placed on or near the
host plant from May until August. The traps are monitored for suspects and
serviced once a month. If suspects are found they are sent to the University of
Wyoming for further identification.
