Emerald ash borer proves an elusive catch

  • Updated: July 23, 2009 - 9:31 AM

Minnesota Department of Agriculture technician Jonathan Osthus checked an emerald ash borer attractor in St. Paul Wednesday, but he found little more than flies.

State agriculture officials say that only proves how difficult the bug is to find before it has begun destroying trees.

The two bugs found in 1,800 traps in Minnesota this summer were near the St. Paul neighborhood where the state's first ash borer infestation was detected, in May.

Only a few healthy and treated ash trees, among the 900 million in Minnesota, might survive an infestation, based on experience in other states.
