Dendroctonus frontalis, the southern pine beetle, [1] often shortened to simply SPB, is a species of bark beetle native to the forests of the southern United States, Mexico and Central America. [2] It has recently expanded its range to the northeastern United States, where it is considered an invasive species and has destroyed massive amounts ...
Massive outbreaks of mountain pine beetles in western North America after about 2005 have killed millions of acres of forest from New Mexico to British Columbia. [20] 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]
Pinyon pines respond to beetle attacks by creating pitch tubes – an inundation of sap at the site of the initial hole bored by the beetle. The sap defends the tree by pushing out the beetle and sealing the wound. Water stress can compromise the effectiveness of the pitch tube defense, requiring less effort from the beetle for a successful ...
The mountain pine beetle (Dendroctonus ponderosae) is a species of bark beetle native to the forests of western North America from Mexico to central British Columbia. It has a hard black exoskeleton, and measures approximately 5 millimetres (1⁄4 in), about the size of a grain of rice. In western North America, an outbreak of the beetle and ...
Description. Common names include pine sawyer, western pine sawyer, spined woodborer, and ponderosa pine borer. [2] A taxonomic synonym is Ergates spiculatus. [2] This beetle species develops on fallen ponderosa pines and Douglas firs. [3] T. spiculatus is the largest species of wood boring beetle in Colorado.
September 10, 2024 at 5:02 AM. An old nemesis of North Carolina's pine forests is having a resurgence in other Southeastern states as southern pine beetle outbreaks are decimating forest stands in ...
Dendroctonus valens, also known as the red turpentine beetle, is a species of bark beetle characterized by a dark-reddish brown hue. It is native to forests across North and Central America. [1] [2] In its adult form, these beetles range from six to ten millimeters in length. A notable characteristic about them is their use of acoustic signals ...
The nematodes drop off the beetle, and infect healthy pine trees when the adult beetles eat the young pine branches. [16] The pine wilt nematode is spread by a number of bark beetles and wood borers, typically associated with the genus Monochamus of pine sawyers. [17] Pine sawyers lay their eggs in the bark of dead timber.
