| Citrus longhorned beetle is native to Asia and occurs primarily in
China, Korea, and Japan. It has been found in, and eradicated from,
Georgia, Wisconsin, and Washington. It was most likely introduced
on wood packing material or in live plant material. It is known to
attack and kill more than 100 species of plants and includes several
species in the Citrus genus as well as peach, cherry, pecan, maple, oak,
ash, elm, and walnut. Larvae are white, opaque, legless grubs typical
of longhorned beetles. When mature, they are 1 3/4 to 2 1/3 inches
long and about 1/3 of an inch wide with an amber colored head and
black mouthparts. Adults emerge from April to August. Adults are
1 – 1 1/2 inches long and shiny black with white markings. Antennae
are at least as long as the body and have alternating black and white
bands. The ventral surface is pubescent. The color of the pubescence
varies from white to blue depending on location. An important
identifying characteristic of Citrus longhorned beetle is the presence
of two pairs of polished white bumps at the base of the elytra. These
are visible with a 10x hand lens and are not present on the Asian
longhorn beetle, Anoplophora glabripennis. Damage includes distinct
round or slightly oval shaped adult exit holes on the bark surface, T-shaped
oviposition holes, sawdust-like frass or wood pulp around
small holes, and larval tunnels in the wood under loose or thin bark. |
