Latest Curculionidae Stories
A naturally occurring fungus might help curb the spread of an invasive tree species that is threatening forests in most of the United States, according to researchers.
An infestation of bark beetles is killing trees in the mountains across the western US. And now researchers are questioning what effect this massive tree die-off has on stream flow and water quality.
Trees with smoother bark are better at repelling attacks by mountain pine beetles, which have difficulty gripping the slippery surface, according to a new study by the University of Colorado Boulder.
University of Alberta researchers are closing in on finding an effective bait to get ahead of the destructive spread of mountain pine beetle, which is now killing not only lodgepole pine forests, but jack pine.
The bottomless pit of insect biodiversity has yielded a treasure trove of new species of jewel-like clown beetles.
Climate change affects forests across North America – in some cases permitting insect outbreaks, plant diseases, wildfires and other problems -- but Dartmouth researchers say warmer temperatures are also making many forests grow faster and some less susceptible to pests, which could boost forest health and acreage, timber harvests, carbon storage, water recycling and other forest benefits in some areas.
A new University of Colorado Boulder study indicates drought high in the northern Colorado mountains is the primary trigger of a massive spruce beetle outbreak that is tied to long-term changes in sea-surface temperatures from the Northern Atlantic Ocean, a trend that is expected to continue for decades.
Beetles with unusual "green thumbs" for growing fungi are threatening avocado crops and could transform into a more destructive pest, according to an international team of researchers.
‘Keep it simple’ is a good rule of thumb when designing biocontrol programs to combat weeds and invasive plants.
Lodgepole pine (Pinus contorta) is found in western North America in the upper mountains and subalpine regions of Colorado’s northern Rocky Mountains. This tree is considered to be invasive in New Zealand. This tree is also known as the shore pine, twisted pine, and contorta pine as well as black pine, scrub pine, and coast pine. The Lodgepole pine grows best between 8000 and 10,000 feet above sea level. They like to grow in well-drained, slightly acidic, sandy soils on gentle south...
A weevil is a beetle from the Curculionoidea superfamily. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). They are typically small, measuring less than Â¼ inch (6mm), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. Weevils are destructive to crops. One example is the grain or wheat weevil (Sitophilus granarius), which damages stored grain. The boll weevil (Anthonomus grandis)...
- Withering but not falling off, as a blossom that persists on a twig after flowering.
