The Summer Fruit Moth (Adoxophyes orana) is a pest of apple, pear, cherry, plum, apricot, red currant, and many forest trees. Its larvae attack leaves and also can feed on fruit. Surveys are conducted because of the presence of potential host material in Wyoming, the long-distance wind dispersal of this pest, and high potential for establishment after introduction. To date, it has not been found in Wyoming or in the United States. One hundred thirty-five total traps have been placed throughout twenty-three counties in Wyoming.
The Summer Fruit Moth 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.
