A possible solution to the ash borer problem, in the form of a teensy tiny wasp
This week, the Canadian Food Inspection Agency approved the release of wasps that prey on the emerald ash borer. It will be a while before the Tetrastichus might be found in Ottawa, where the ash borer is a big problem. But in the meantime, the Asian wasps are being bred in a facility just over the border in Michigan, about 70 kilometres west of Detroit. Dr. Jonathan Lelito is with the United States Department of Agriculture. He manages that facility, and he explained to us how it's helping get rid of the ash borer in the U.S.
