Southern Pine Beetle Pine bark beetles are insects that normally attack stressed and dying pine trees, and usually do not infest trees that are otherwise healthy and vigorous. Adult beetles can be found on and around host plants during the summer. Mountain pine beetles bore through the bark of pine trees, killing the tree. Meanwhile, scientists like Carroll say increased climate variability and warmer temperatures are going to boost the number of outbreaks of beetles and other insects in the decades to come. Bark beetle data were from annual maps depicting the areal extent of tree canopy mortality due to 12 bark beetle species produced from aerial surveys, forest inventory measurements, and high-resolution satellite imagery (Meddens et al., 2012). Once active, you will need to first protect the trees surrounding the one with activity and then make some decisions regarding the infested tree which could include using a systemic like Prothor. Southern Pine Beetle Pine bark beetles are insects that normally attack stressed and dying pine trees, and usually do not infest trees that are otherwise healthy and vigorous. There are 600 different species of bark beetles in the United States. Southern pine beetle (SPB) is a bark beetle that infests pine trees. Landsat image taken in 1992 shows the Uinta Mountains east of Salt Lake City. These small cylindrical insects attack and kill mature trees by boring through the bark and mining the phloem - the layer between the bark and wood of the tree. DEC Technical Report . The pests would feast on mature trees, providing fuel for forest fires that would then spur new growth. Helicopters scour areas of Alberta’s northern timberland looking for signs a pine tree’s green needles have turned a ghastly red. Landsat image of the same area in 2010 captures the dramatic assault of mountain pine beetles. The treatment for pine beetles works best when applied proactively before an infestation is detected. Bark beetles range from Canada to Mexico and can be found at elevations from sea level to 11,000 feet. An outbreak is defined as one or more multiple-tree southern pine beetle infestations per 1000 acres of susceptible host type. DEC Southern Pine Beetle- Suppressed Stand Characteristics Research Summary. The bugs are able to thrive as forests become stressed and the markets often don’t accommodate what he calls the solid and beautiful truth: “ecology trumps all.”, “I’m astonished how an animal the size of a grain of rice could alter the ecological landscape,” Carroll said.
