Chinese Tetrastichus wasps used against the Emerald Ash Borers

/in /by

In the battle against the invasive emerald ash borer, Chinese parasitic wasps are beginning grown and released. Over the next couple months 10,000 to 12,000 of these tiny insects will be released and this isn’t the first time the wasps have been bred in Canada. The emerald ash borer is an invasive species and is highly destructive to ash trees, within six years an emerald ash borer infected woodlot will kill almost 100% of the ash trees. The female wasps seek out EAB larvae, boring through ash bark and laying their eggs (up to 60 of them) on EAB grubs. When the eggs hatch, they eat the grubs and emerge as new baby wasps. The ant sized wasps don’t pose any danger to humans. The Canadian government is looking at using two different Chinese wasps and one Russian wasp, which is pending approval.
