The Silver Y Moth (Autographa gamma) is a pest of beet, potato, cereals, vegetables, and nursery plants. Its larvae are leaf feeders and also can feed on fruit. Surveys are conducted because of the presence of potential host material in Wyoming and high potential for establishment after introduction. It has not been found in the US.
The Silver Y Moth Survey is conducted by the Wyoming Pest Detection / CAPS Program. A plastic bucket 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.
