Pine Beetle

	Pine Beetle ''Dendroctonus'' is a genus of bark beetles. It includes several species notorious for destroying trees in the forests of North America. The genus has a symbiotic relationship with many different yeasts, particularly those in the genera '' Candida'' and ''Pichia'' that aid in digestion and pheromone production. Species include: '' Dendroctonus adjunctus'' - roundheaded pine beetle ''Dendroctonus approximatus'' - Mexican pine beetle ''Dendroctonus barberi -'' southwestern pine beetle '' Dendroctonus brevicomis'' - western pine beetle ''Dendroctonus frontalis'' - southern pine beetle '' Dendroctonus jeffreyi'' - Jeffrey pine beetle ''Dendroctonus mesoamericanus'' - Mesoamerican pine beetle ''Dendroctonus mexicanus'' - smaller Mexican pine beetle ''Dendroctonus micans'' - great spruce bark beetle '' Dendroctonus murrayanae'' - lodgepole pine beetle ''Dendroctonus parallelocollis'' - larger Mexican pine beetle '' Dendroctonus ponderosae'' - mountain pine beetle '' Den ...

picture info	Dendroctonus Ponderosae 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 , about the size of a grain of rice. In western North America, a recent outbreak of the mountain pine beetle and its microbial associates has affected wide areas of lodgepole pine forest, including more than of forest in British Columbia. The outbreak in the Rocky Mountain National Park in Colorado began in 1996 and has caused the destruction of millions of acres/hectares of ponderosa and lodgepole pine trees. At the peak of the outbreak in 2009, over were affected. The outbreak then declined due to better environmental conditions and the fact that many vulnerable trees had been already destroyed. Mountain pine beetles inhabit Pinus ponderosa, ponderosa, Pinus albicaulis, whitebark, Pinus contorta, lodgepole, Scots pine, Scots, jack pine, jack, Pinus ...

	Dendroctonus Valens ''Dendroctonus valens'', the red turpentine beetle, is a species of bark beetle native to the forests of North America, Mexico, Guatemala and Honduras. It has been introduced to China where it has become invasive. In its native range it causes little damage, but in China it is a destructive pest and has killed more than six million pine trees. Description The eggs are cylindrical with rounded ends, white, opaque and shiny, and about long. The larva is a white, legless grub, with a brown head and brown tip to the abdomen. As it grows, lateral rows of pale brown tubercles become apparent. The fully grown larva is long. The pupa is white; it is exarate, the antennae and legs being free and not enclosed in a cocoon. The adult beetle is long and about twice as long as it is wide. When it first emerges from the pupa it is tan, but it soon turns dark reddish-brown.
