Survey Information

The Siberian Moth (Dendrolimus superans sibiricus) is a pest of fir, pine, spruce, cedar, and other coniferous trees. Egg masses are laid in clusters on needles, and larvae defoliate host trees. To date, it has not been found in Wyoming or the US. The Wyoming Siberian Moth Survey was not conducted before 2007. Twenty-five total traps have been placed throughout twenty-three counties in Wyoming.

The Wyoming Siberian 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.
