Survey Information

The Golden Twin-spot Moth (Chrysodeixis chalcites) is a potential pest of tomatoes and legumes. Surveys are conducted because of the presence of potential host material in Wyoming, particularly dry beans. All larval instars damage plant foliage through feeding. It has not been found in the US. To date, it has not been found in Wyoming. Forty-five total traps have been placed throughout twenty-three counties in Wyoming.

The Wyoming Golden Twin-spot 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.
