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.
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 adult wood-boring beetles lay their eggs in a crevice in the bark of hardwood trees, such as Oregon ash, New Mexico willow, and California laurel/Oregon myrtle. [1] From there the larvae bore into the wood.
Woodboring beetles most often attack dying or dead trees. In forest settings, they are important in the turnover of trees by culling weak trees, thus allowing new growth to occur. [ 3 ] They are also important as primary decomposers of trees within forest systems, allowing for the recycling of nutrients locked away in the relatively decay ...
Furthermore, Ips pini beetles possess the capability to act as vectors for a particular type of blue stain fungus, which plays a crucial role in the beetles' ability to kill their host trees. This process involves the fungus clogging the water transportation systems within the tree, effectively disrupting the tree's ability to transport water.
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.
Monochamus is a genus of longhorn beetles found throughout the world. They are commonly known as sawyer beetles or sawyers, as their larvae bore into dead or dying trees, especially conifers [1] such as pines. They are the type genus of the Monochamini, a tribe in the huge long-horned beetle subfamily Lamiinae, but typically included in the ...
Chalcophora angulicollis, known generally as the western sculptured pine borer or sculptured pine borer, is a species of metallic wood-boring beetle in the family Buprestidae. They are found in dry parts of the world such as the western parts of North America. They have a dark brown textured shell with a shimmery gradient. [1] [2] [3]
