'Fusarium dieback' severely damaged avocados in Israel, says UC Riverside plant pathologist Akif Eskalen, who identified the fungus A plant pathologist at the University of California, Riverside has identified a fungus that has been linked to the branch dieback and general decline of several backyard avocado and landscape trees in residential neighborhoods of Los Angeles County. The fungus is a new species of Fusarium . Scientists are working on characterizing its specific...

Climate change puts spruce forests at greater risk of bark beetle attacks Climate change appears to be good news for destructive bark beetles, according to a new study by Lorenzo Marini from the University of Padova in Italy, and his team. Their work, published online in Springer's Climatic Change, shows that there were more attacks by the spruce bark beetle on European Alpine spruce forests over a 16 year period, as temperatures rose and rainfall dropped. Shifts in temperature,...

Periodic outbreaks of bark beetles can cause annual losses of millions of dollars and pose serious challenges for forest managers, and the suppression of outbreaks is particularly difficult and expensive. According to T. D. Schowalter, author of a new open-access article in the Journal of Integrated Pest Management called "Ecology and Management of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern Pine Forests," preventative measures are most effective in minimizing losses...

Warming temperatures appear to allow pine beetles to now breed twice a year Long thought to produce only one generation of tree-killing offspring annually, some populations of mountain pine beetles now produce two generations per year, dramatically increasing the potential for the bugs to kill lodgepole and ponderosa pine trees, University of Colorado Boulder researchers have found. Because of the extra annual generation of beetles, there could be up to 60 times as many beetles...

The coffee berry borer, Hypothenemus hampei (Ferrari), is considered one of the most serious pests in coffee plantations worldwide. Infestations of this small beetle are difficult to combat; most of the insect's lifecycle is completed inside coffee berries, making insecticide penetration and contact difficult. Female beetles bore holes into developing berries attached to the tree through the blossom scar and create ℠galleries´ where they remain and deposit their eggs. The...

The problem of invasive species may seem remote from most people's lives. But in some parts of the United Kingdom, an invasive plant creates a problem that hits home, literally. That's because the presence of invasive knotweed on a property prevents potential buyers from obtaining a mortgage. This destructive plant from Asia, which can tear down walls and rip up roads, is also putting down roots in many parts of Canada. Research by Judith Myers, an ecology professor emerita at the...

The southern pine beetle, Dendroctonus frontalis Zimmermann, is a chronic insect pest within pine forests in the southeastern United States. Under favorable environmental and host conditions, it is an aggressive, primary bark beetle capable of killing large acreages of pines. Its principal range stretches from east Texas and Oklahoma to the east coast and north to southern New Jersey. In "Implications of Population Phases on the Integrated Pest Management of the Southern Pine Beetle,...

North Carolina State University researchers have found that a subset of fungus-farming ambrosia beetles may be in the early stages of a global epidemic threatening a number of economically important trees, including avocados, poplars and oaks. "Only about 12 species of ambrosia beetle are creating problems so far, but there are thousands of other species in the world, many of which could be devastating to any number of tree species," says Dr. Jiri Hulcr, a postdoctoral research associate at...

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)...
