A new insect that will help control the invasive weed waterhyacinth has been released by Agricultural Research Service (ARS) scientists and cooperators. Waterhyacinth (Eichhornia crassipes) is a free-floating aquatic plant native to South America that has infested freshwater ecosystems from North Carolina to California but is especially problematic in the southeastern United States. The plant is a real menace, affecting water traffic, water quality, infrastructure for pumping and...

The area burned by fire each year is expected to double "“ or even triple "“ if temperatures increase by about 3.5 degrees Fahrenheit (2 C) in our region, according to University of Washington and USDA Forest Service research. Such temperature increases could occur in as little as 40 years, according to projections from the UW's Climate Impacts Group. "I'm not a doom-and-gloom kind of guy but this is a great concern," said Dave Peterson, a UW professor of forest resources and a...

At last there's a predator for the most widespread coffee pest, new study shows There is good news for coffee lovers and growers worldwide: A predator for the devastating coffee berry borer has just been discovered in Africa. Looking at coffee berries in Western Kenya, Dr. Juliana Jaramillo from the International Centre of Insect Physiology and Ecology in Kenya, Dr. Eric Chapman from the University of Kentucky, and colleagues have identified a previously unknown predatory thrips* "“...

UBC researchers have helped developed a cheaper, faster way to compile draft genome sequences that could advance the fight against mountain pine beetle (MPB) infestation and improve cancer research. Current sequencing methods have a variety of advantages and disadvantages--including the cost involved. Dr Steven Jones and colleagues at UBC, the BC Cancer Agency and Simon Fraser University have combined cutting edge hardware with novel software to compile genome sequences at a fraction of the...

An infestation of beetles in forests across North America has some regulators concerned over the increasing carbon footprint their devastation could leave behind. So far, the infestation has killed off millions of acres of pine forests in the US and Canada, and millions of spruce trees could be the next to go. "The gravity of the situation is very real," Rolf Skar, of Greenpeace, told Reuters. To date, the beetle swarms have resulted in a loss of billions of dollars in the timber industry as...

A tree-killing fungus near Florida's Everglades National Park could harm the area's $12.7 million avocado industry, agriculture officials said. "At this point, if your tree becomes infected, it will die,'' state Agriculture and Consumer Services spokesman Mark Fagan told The Miami Herald. Scientists recently discovered a case of laurel wilt disease, carried by the invasive redbay ambrosia beetle, in an avocado sample taken from a grove in Homestead, Fla., between Biscayne National Park and...

Scientists fear that the swarms of mountain pine beetles that have killed more than half of all lodge pole pines in British Columbia may eventually make their way into forests in the US. And while cold winters typically kill most of the beetle larvae, the region has recently witnessed unusually higher temperatures that have allowed the beetle to thrive for longer periods of time. The beetle has recently been found in Alberta, and scientists told BBC News that they could threaten jack pine...

Florida's thriving avocado industry could be in danger due to the arrival of the redbay ambrosia beetle. Scientists say the little beetle (Xyleborus glabratus) spreads a fungus called laurel wilt disease that kills off avocado trees. The implications of the beetles' arrival into Florida could spell out danger for the state as it is the second-largest source of avocados in the US. The adult female redbay ambrosia beetle carries in a special pouch in its mouth -- called a mycangia -- the...

A researcher at North Carolina State University is tracking the movement of the Redbay Ambrosia beetle, an invasive insect that, if it spreads to southeast Florida, may severely affect the production of avocados, a $15 million to $30 million industry in the state. First detected in the United States near Savannah, Ga., in 2002, the beetle had spread to Hilton Head Island, S.C., by 2004, causing widespread mortality in Redbay trees. Dr. Frank Koch, a research assistant professor at NC State...

Mountain pine beetles devastating lodgepole pine stands across the West might best be kept in check with aerial application of flakes containing a natural substance used in herbal teas that the insects release to avoid overcrowding host trees, according to a team of scientists.Findings from the U.S. Forest Service-funded study appear in the February issue of Forest Ecology and Management. The study was conducted in California and Idaho, and showed how applications of laminated flakes...

Lodgepole Pine, Pinus contorta
2014-04-27 08:06:16

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 ¼ 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)...
