Pests that are associated with specific commodities are relatively easily managed by biosecurity agencies. Unfortunately, many high risk organisms are not restricted to well defined pathways and these hitchhiker pests can present significant inspection, detection and treatment challenges for biosecurity agencies. Two recent cases that were dealt with by the Australian Quarantine and Inspection Service (AQIS) are discussed, highlighting some of the responses undertaken to manage hitchhiker organisms. These were the detections of egg masses of the saturniid moth (Hylesia nigricans) on vehicles imported from Argentina, and burnt pine longicorn beetles (Arhopalus ferus) on the cruise ship ‘Queen Elizabeth’.
