The Light Brown Apple Moth (Epiphyas postvittana) is a potential pest of many different horticultural and native plants. Its larvae bore into and feed on the fruit. Surveys are conducted because of the presence of potential host material in Wyoming. In the US, it has been found in California. To date, it has not been found in Wyoming.
The Wyoming Light Brown Apple Moth Survey is conducted by the Wyoming Pest Detection / CAPS Program. A Jackson 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.
