Though the vast majority of woodboring beetles are ecologically important and economically benign, some species can become economic pests by attacking relatively healthy trees (e.g. Asian longhorn beetle, emerald ash borer) or by infesting downed trees in lumber yards. Species such as the Asian longhorn beetle and the emerald ash borer are ...
The cottonwood borer (Plectrodera scalator) is a species of longhorn beetle found in the United States east of the Rocky Mountains that feeds on cottonwood trees. [3] It is one of the largest insects in North America, with lengths reaching 40 millimetres (1.6 in) and widths, 12 mm (0.47 in). It is the only species in the genus Plectrodera. [4]
The emerald ash borer (Agrilus planipennis), also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species (Fraxinus spp.). Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.
The emerald ash borers' larvae burrow into the bark of ash trees, causing canopy dieback and, ultimately, tree death. The half inch beetle is often challenging to detect, especially in newly ...
Bark beetles enter trees by boring holes in the bark of the tree, sometimes using the lenticels, or the pores plants use for gas exchange, to pass through the bark of the tree. [3] As the larvae consume the inner tissues of the tree, they often consume enough of the phloem to girdle the tree, cutting off the spread of water and nutrients.
The Asian longhorned beetle is a wood-boring insect that attacks 12 types of hardwood trees in North America, including maples, elms, buckeyes, birches and willows. Infested trees do not recover ...
A few species are serious pests. The larvae, called roundheaded borers, bore into wood, where they can cause extensive damage to either living trees or untreated lumber (or, occasionally, to wood in buildings; the old-house borer, Hylotrupes bajulus, is a particular problem indoors).
Prionus laticollis, also known as the broad-necked root borer or broad necked prionus, is a root-boring longhorn beetle described by Dru Drury in 1773. [ 1 ] [ 2 ] It is widespread throughout eastern North America : its range covers a vast swath from Quebec in the northeast to Arkansas in the southwest.
