Latest Curculionidae Stories
By Karl Puckett Amy Gannon, hatchet in hand, sliced a slab of bark from a lodgepole pine tree near Wolf Creek, Mont., and quickly spotted a mountain pine beetle larva no bigger than her pinkie fingernail.
By Christine Weeber Pesticides often have larger effects than we intend. Some of those used in responding to the mountain pine beetle infestation are no different. Carbaryl, the active ingredient in the most common sprays used to protect trees against beetles, is one of these.
The USDA Forest Service Southern Research Station (SRS) today announced that an SRS scientist and other researchers have officially named the fungus responsible for killing redbay and other trees in the coastal plains of northeastern Florida, Georgia, and South Carolina.
By Cramer, John Scientists, economists, land managers and others will gather Thursday in Missoula to discuss the worsening infestation of bark beetles across the West. "Red Tree," a one-day public symposium, is scheduled from 9 a.m. to 5 p.m.
An outbreak of pine beetles is to blame for the destruction of almost 33 million acres of lodgepole pines in British Columbia, resulting in a massive release of carbon equal to five years of emissions from the entire system of Canadian transport.
Global warming could be the cause behind a beetle infestation killing off lodgepole pine forests in Colorado. About 60 percent of the lodgepole pines have turned red and brown. Whether global warming is to blame or not, the evidence is daunting.
Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. University of Illinois ecologist Adam Davis has created a computer model that in combination with quarantined research tests he believes will be able to predict the perfect predator -- a pest that can be introduced into a forested area that will help reduce the garlic mustard population.
Most of Coloradoâ€™s lodgepole pine trees stand to be dead within the next 5 years. In 1996, a bark beetle infestation was detected, and last year it spread over 500,000 acres more than previous years. Federal forestry officials say that this brings the total count of affected acres to 1.5 million.
By HANNAH ZITNER VANCOUVER (CP) - Three B.C. mayors are demanding the federal government help thousands of homeowners pay for removing mountain pine beetle-infested trees.
By SHANNON MONTGOMERY EDMONTON (CP) - Alberta wants forestry companies to step up the cutting of pine trees to help deal with a massive outbreak of destructive mountain pine beetles.
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)...
