New York's Ash Trees Threatened by Newly Found Beetle

22.06.2009
For the first time, Cornell researchers have reported the sighting of the emerald ash borer – an ash-destroying beetle – in New York state.

“The threat is extreme,” said E. Richard Hoebeke, a senior extension associate in entomology at Cornell. “There is the potential for ash as we know it to be extirpated from the landscape.”

The U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) in Washington, D.C., announced on June 18 they had officially identified the Emerald Ash Borer in New York after receiving and examining specimens sent by Cornell researchers earlier this week.

The flying Asian beetle was discovered in ash trees near Randolph in Cattaraugus County in southwestern New York. New York has some 900 million ash trees, representing about 7 percent of all trees in the state, and all are at risk should this invasive, exotic pest become established.

The beetle, which has metallic green wing covers and a coppery red or purple abdomen and is small enough to fit on a penny – was first discovered in the United States in Michigan in 2002 and has since decimated more than 70 million ash trees in 13 Midwestern states and Pennsylvania, as well as many in southern Ontario and Ottawa in Canada. The beetle’s larvae girdle under a tree’s bark, killing the tree in one to three years.

On June 14, John Vandenberg, a Cornell adjunct professor in entomology, and and Michael Griggs, both entomologists at the USDA-ARS in Ithaca, were driving to Michigan on Route 17 to study the beetle when they stopped to examine some damaged trees along the road. Upon sighting the beetles, which appear to have been in the area for a few years, they contacted Hoebeke, who immediately drove to the site from Ithaca.

Hoebeke collected specimens and overnight mailed them to the USDA-ARS Systematic Entomology Laboratory in Washington, D.C., which then officially identified the emerald ash borer. State and federal agencies now will begin helicopter surveillance of the area and investigate strategies for controlling the invasive pest.

“There’s not a whole lot we’ll be able to do about it,” said Hoebeke. The standard practice of removing infested trees does not effectively stop the ash borers from spreading, he added. Officials plan to survey trees throughout the state and start an intensive effort to trap the ash borers in infested areas to assess the extent and age of the infestation. Information from this survey will help determine the response strategy, which could range from tree removals associated with eradication and safety concerns, to ash product quarantines.

The beetle has most likely spread through the country via the transport of infested firewood, even though most states ban the interstate movement of untreated firewood.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
