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]
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 ...
Mountain pine beetles can damage whole regions of forest. Mountain pine beetles affect pine trees by laying eggs under the bark. The beetles introduce blue stain fungus into the sapwood that prevents the tree from repelling and killing the attacking beetles with tree pitch flow. The fungus also blocks water and nutrient transport within the tree.
Tiny bark beetles, namely the Ips engraver and southern pine varieties, have been killing millions of trees across Louisiana and Mississippi after a severe drought last year left forests and woods ...
Ips pini, also known as the pine engraver or North American pine engraver, is a species of typical bark beetle in the family Curculionidae found primarily in North America. These beetles are subcategorized by the distinctive geographic ranges in which they are found.
Still, southern pine beetle infestations in 2023 represented "the most wide-spread activity in the Southern region in the past two decades," according to the information center. Southern pine ...
Species closely related to Tomicus piniperda include Tomicus minor (lesser pine shoot beetle), with a similar distribution but ecologically separated, using standing dead pines and with its breeding galleries across the grain, not parallel to it; [2] Tomicus destruens in the Mediterranean region, which differs in details of ecology, infesting primarily stone pine P. pinea and maritime pine P ...
In response to the unprecedented spread of bark beetles in the Rocky Mountains and other parts of the western United States, the U.S. Forest Service formed the Western Bark Beetle Research Group (WBBRG) in 2007—a collaboration between scientists from three research stations that pools knowledge and resources to better understand the threat and eventually develop a strategy to combat it.
