Banded Elm Bark Beetle wreaks havoc on Powell trees

(Powell, Wyo.) - The Powell Tree Advisory Board recently met to discuss the significant impact the Banded Elm Bark Beetle (BEBB) is having on Siberian Elm (Ulmus pumila) trees in the Powell area. The BEBB has spread throughout the west since 2003. This small beetle lays eggs on the bark of the tree and the hatching larvae burrow under the bark. Large galleries form as the larvae feed on the phloem. Movement of water and nutrients in the tree becomes disrupted and severe attacks of the insect kills the tree. Early detection of the insect is key and movement of firewood will spread the insect to other areas. According to Powell Parks and Recreation, any tree that is infested must be removed and the tree parts must be chipped, sealed in plastic and left in the sun, bark removed, or burned immediately. This beetle is also thought to carry the fungal spores of Dutch elm disease. Once the insect has established it can be very difficult to control. Insecticide treatment in the spring includes a basal drench of Merit, imidacloprid is the active ingredient. Consult with a certified plant health care professional for more information.
