(15-047) Species: Pissodes approximates Host: Red pine, Scotch pine Secondary host: Eastern white pine, pitch pine, Jack pine, shortleaf pine, Virginia pine, Table Mountain pine, Austrian pine, white spruce, red spruce, black spruce Range: Northeast states southward to Minnesota and North Carolina Injury: Adults emerge in the spring and feed on the inner bark of branches and stems of seedlings and small trees. It breeds beneath the bark surface. It breeds on recently cut stumps and logs, and on the main stems or branches of dead or dying trees. Attacks occur on the tree from the roots up to branches as small as ½ inch in diameter. Attacks also occur at the root collar and on the lower stems of apparently healthy young trees. Description: Adult is 5 to 8 mm long. The beak is large, and the spots on the elytra are uniformly small. (15-048) Species: Pissodes dubius Host: Noble fir, balsam fir, red spruce Range: Noble fir in California, Oregon, Washington, Idaho; balsam fir and red spruce in the northeastern states Injury: Larvae mine the inner bark. The adults pierce the bark or buds and feed. Attacks and breeds in storm damaged 90-year-old noble fir and attacks nearby intermediate and suppressed trees. Attacks are made in the root crown area. Description: This is the largest species in the genus. Adults are 7.5 to 10 mm long, and dork brown to black in color. Adults are rough surfaced beetles, usually with spots and patches of white, yellow, of brown scales on the elytra.
