State agricultural officials have placed a quarantine on firewood from three counties due to a destructive insect infestation.  Pest control crews have found  evidence of a beetle known as the Emerald Ash Borer for the first time in North Carolina.  It makes its home in ash trees and kills them over a period of two to three years.  The quarantine applies to any wood products made from ash trees in Granville, Person and Vance Counties. 

Phil Wilson of the state Agriculture Department says the bug spreads by flying from tree to tree or by lumber transportation.

Aquatic Plant Pest Spreads To Eastern NC

An invasive plant called hydrilla is spreading from the Piedmont toward lakes near the coast. 

Biologists say the aquatic weed first found in Wake County is now on river banks in northeastern North Carolina and in lakes near Wilmington.  Dr. Rob Richardson is a crop science professor at N.C. State University.  He says the plant grows in thick patches, which can cause problems in drinking water supplies.

"Large mats have, at times, clogged turbines," says Richardson.

Scientists are keeping a close eye on North Carolina's shrimp population as fishermen see more of an invasive species known as tiger shrimp. Fishermen have reported catching more than 200 this season. That's up from an average of 10 to 20 since 2008. James Morris is an ecologist with NOAA's Center for Coastal Fisheries and Habitat Research in Beaufort. He says more tiger shrimp could mean a smaller catch for North Carolina's traditional shrimpers.

An insect that feeds on invasive kudzu is making its way into North Carolina. The so-called kudzu bug was first discovered in Georgia several years ago. Jack Bacheler is an entymologist with N.C. State University. He says the problem is the beetle, called the bean plataspid, also likes crops like soybeans.

NC Prepares for Foreign Beetle

An Asian beetle that first turned up in Michigan is threatening to spread to North Carolina. The Emerald Ash Borer arrived in the U.S. about ten years ago. Since then it's spread from the midwest, to most of the states surrounding North Carolina. Brian Haines works for the state Forest Service.

Colleges Check for Bedbugs as Students Return

Bedbugs have recently been found on the campus of Wake Forest University. Officials say dogs discovered evidence of the pests in a very small number of dorm rooms. Those rooms have been treated and are expected to be free of bedbugs as students arrive. Michael Waldvogel is an associate professor of entomology at North Carolina Statue University. He says N.C. State and Wake Forest use heat generating equipment to deal with any outbreaks of bedbugs.

NC Warns Against Invasive Plants

North Carolina's first Invasive Plants Awareness Week begins today. State officials are encouraging residents to keep aggressive vines like kudzu and wisteria out of their gardens. Experts say invasive plants can wipe out large areas of vegetation native to North Carolina.  Debbie Crane of the North Carolina Nature Conservancy says they can also deal a blow to the state's tourism industry.
