Scolytini Pine Bark Beetles are small reddish to dark brown beetles about 1/4 to 1/2 of an inch long. Beetles are insects which are found in almost every country in the world. It is also interesting to know that some of them feed on smaller preys, such as the rove beetles. Many are also attracted to ethanol, one of the byproducts of microbial growth in dead woody tissues. During the past decade in the west, tree mortality caused by bark beetles has increased in spruce, lodgepole, pinyon-juniper, and ponderosa forests. These events are part of the ecology of western forests and positively influence many ecological processes, but their adverse economic and social implications can also be significant. [4] Sap is one of the first line of defense of pines against bark beetles. Spruce beetle damage results in the loss of 333 to 500 million board feet of spruce saw timber annually.

Spruce beetles (Dendroctonus rufipennis) are native bark beetles that infest Engelmann spruce (Picea engelmannii) and occasionally Colorado blue spruce (P. pungens) in high elevation forests in Colorado.The spruce beetle typically completes a generation in one to three years, with a two-year life cycle being the most common in spruce trees growing above 9,000 feet. Healthy trees may put up defenses by producing sap, resin or latex, which may contain a number of insecticidal and fungicidal compounds that can kill or injure attacking insects, or simply immobilize and suffocate them with the sticky fluid. Bark beetles are tiny insects with hard, cylindrical bodies that reproduce under the bark of trees. There are 4,200 species of beetle in Britain, and more than 1,000 live in trees and woodland habitats. They can live in the land, they can live underground and even in water!

[citation needed], Like many other insects, Scolytinae emit pheromones to attract conspecifics which are thus drawn to trees already colonized by bark beetles. [14], Manually decorticated trunk of a spruce as protection to bark beetles, In undisturbed forests, bark beetles serve the purpose of hastening the recycling and decomposition of dead and dying wood and renewing the forest. Most, however, live in dead, weakened, or dying hosts. »The name ‘Bark Beetle’ is given to these species because they reproduce in the inner bark of the tree. [citation needed]. Thamnurgini Serv., Ottawa, For. Cortylini Elm bark beetles are super small, like the size of a grain of rice. Beetles can live in almost all kinds of environments.
