Six step process for identifying, testing, releasing, and managing biological control agents:

  1. Recognize that an exotic species is, or may become, an invasive threat.
  2. Conduct exploratory surveys for potential biological control agents in the invasive plant’s native range.
  3. Screen the most promising agents for host specificity (that is, ecological safety).
  4. Apply for permission to release the biological control agent.
  5. Establish self-perpetuating populations of safe biological control agents.
  6. Develop management strategies to enhance efficacy of naturalized biological control agents.
