The Apple Tortrix (Archips fuscocupreanus) attacks a broad range of fruit trees. Surveys are conducted because of the presence of potential host material in Wyoming and potential introduction pathways from surrounding states. It has been found in the coastal areas of the northeast US and the coastal regions of Washington. To date, it has not been found in Wyoming. Eighty-four total traps have been placed throughout twenty-three counties in Wyoming.
The Wyoming Apple Tortrix 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.
