Biological control of emerald ash borer (EAB)


 

The goal of EAB biological control is to use natural enemies to bring EAB populations into balance and reduce damage.  More information about biological control in general

  • Biological control is the only management option that can be applied at the forest landscape level.
  • Two parasitoid wasp species are released in Minnesota.  One species attacks the larval stage of EAB under the ash bark.  The other species kills EAB eggs that are in bark crevices.  These wasps are small like gnats and do not harm humans.  They were selected by the US Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and Forest Service and tested extensively to ensure that they will not negatively impact other species or the environment.  APHIS rears these biological control agents at a specialized facility in Brighton, MI and provides them to states with EAB infestations.
