Using Fungus To Stop Invasive Spread Of Tree-Of-Heaven
2014-05-10 04:00:57

By Matt Swayne, Penn State 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. Researchers tested the fungus -- Verticillium nonalfalfae -- by injecting it into tree-of-heaven, or Ailanthus, plots, according to Matthew Kasson, who recently received his doctorate in plant pathology and environmental microbiology from Penn State. The treatment completely eradicated the...

Fungal-farming Beetle Threatening Avocado Crops
2013-07-18 13:04:01

Penn State 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. Ambrosia beetles are insects that bore into trees and cultivate fungi to use as a food source for their young. The fungi -- species of Fusarium -- carried by types of the Ambrosia beetle can damage or even kill trees, making the beetle and its fungi a threat to avocado production in the U.S....

'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...

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...

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...

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...

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. Lead author and Iowa State University Plant Pathologist Tom Harrington, co-author and SRS Plant Pathologist Stephen Fraedrich, and Azerbaijan National Academy of Sciences Researcher D.N. Aghayeva unveiled the name, Raffaelea...

BOSTON -- A species of beetle never before seen in North America has been discovered in a Massachusetts forest, but the Asian insect does not appear to pose an ecological threat, experts said Monday. Twenty-two beetles belonging to the Xyleborus seriatus species of ambrosia beetle were found in April in traps set by state forestry workers in Southborough, about 25 miles west of Boston. Two or three more were trapped in nearby Stow. The insects were sent to Cornell University to be studied....
