MEMPHIS, Tenn. (AP) -- State and federal agriculture officials are tracking how far the emerald ash borer has advanced. The research involves hanging purple triangular traps in trees across Tennessee.
The U.S. Department of Agriculture said Friday that the beetle has killed tens of millions of ash trees in the eastern United States and Canada. The species is not native to North America.
Tennessee Department of Agriculture spokeswoman Heather Orne told The Commercial Appeal about 1,400 traps are being placed across the state.
Department plant certification administrator Gray Haun said trapping is an important tool to find new infestations and help guide decisions about control measures.
