All of Wisconsin is now under quarantine because of the spread of the emerald ash borer, and a state agency is hoping researchers can come up with a way to deal with the beetle.
Ag department spokeswoman Donna Gilson says they can’t tell right away when the pest moves to another area, since it burrows underneath the bark of ash trees. She says they can’t spray an area, like they do for gypsy moths.
Since the beetle moved into Wisconsin, Gilson says many communities have adjusted and they don’t plant more than 10 percent of the same tree species. She says that limits the number of lost trees, if something would attack a specific species in the future.
