Emerald Ash Borer Found in Missouri

August 7, 2008

Emerald ash borer has been found in southeastern Missouri at Wappapello Lake in the U.S. Army Corps of Engineers’ Greenville Recreation Area in Wayne County. This location is about 70 miles due west of Cairo, Illinois. Seven beetles were found on a purple survey trap. With this being in a camping area, it is likely that the insect was accidentally moved by people in firewood or other means rather than the beetle flying there on its own.

Although a few of the purple survey traps for emerald ash borer had previously been taken down and analyzed, removal of all of the traps across the state began on August 4. It will not be surprising if additional sites remote from known infested areas will be discovered in Illinois.

Remember that insecticide treatment is not recommended more than 15 miles from known emerald ash borer infestations. Our recommendations for control can be found at http://www.ipm.uiuc.edu/landturf/
