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]
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.
Dendroctonus adjunctus, the roundheaded pine beetle, is a species of bark beetle in the family Curculionidae found in North America. [1] [2] [3] A parasite, the roundheaded pine beetle feeds on and eventually kills pine trees of several species in Guatemala, Mexico, and the Southern United States (New Mexico, Arizona, Nevada, Colorado, Utah).
Ips avulsus, the small southern pine engraver, is a species of typical bark beetle in the family Curculionidae. The pheromones ipsenol, ipsdienol, and lanieron combined attract the most colonization in the host material in regards to the chemical ecology of the small southern pine engraver, which also effects their reproduction processes.
This bark beetle feeds on the developing bark on and around the root crowns of tree seedlings, [1] especially the phloem. [3] It also infests stumps , logs, and fallen trees. It prefers pines, and is a widespread pest of wild and cultivated Monterey pines ( Pinus radiata ) in particular. [ 1 ]
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.
Cucujus clavipes is known as the flat bark beetle. [1] [2] It is found throughout North America. [3] These are generally found near tree line [4] under bark [2] of dead poplar and ash trees. [5] C. clavipes are described as phloem-feeding [6] and often predators [1] of other small insects, such as wood-boring beetles, and mites. [5]
The FISC list is a recommendation for natural resource managers, environmental education, and volunteer removal, but is not regulatory by law. [173] State regulated plant species are listed in the State of Florida Noxious Weed List, and the State of Florida Prohibited Aquatic Plants List. [178]
