Survey Information

The Brown Spruce Longhorn Beetle (Tetropium fuscum) is a pest of many pine, fir and spruce species. It is native to northern and central Europe. It has not been found in the United States, but has been intercepted on wood products at ports in the US. Surveys are conducted because of the presence of potential host material in Wyoming. To date, it has not been found in Wyoming.

The Brown SpruceLonghorn Beetle survey is conducted by the Animal and Plant Health Inspection Service, Plant Protection and Quarantine as part of the Exotic Bark Beetle Survey. A cross vane trap with host attractant is placed on or near the host plant from May until September. If suspects are found they are sent to a regional entomologist for further identification.
