What is the problem?
Optimal surveillance design(what’s the best way to look for something you don’t want to find)
biosecurity built on science
What is the problem?
Surveillance- Early detection for rapid and effective response
- Delineating the extent of an incursion- Proving area freedom to protect trade
- Inform management of established pests
biosecurity built on science
What is the problem?
What is the best design for a surveillance system?- Number of samples (traps etc)- Location of sampling- Frequency of sampling- Movement of traps? - Different methods?- New technologies
New kind of trap New diagnostic methods Flight paths of UAVs Adaptive strategies for automated/mobile traps

Who will benefit from this research?
Industry- Potato, grape/wine, fruit- Others
Government Researchers
biosecurity built on science
Benefit for our horticultural industries
Surveillance that is more effective, lower cost, higher confidence
Better justify and target new methods (traps, sampling, diagnostics, automation)
Quicker detection quicker eradication better market access

End-User Advocate’s Perspective
“…The development of models which specify the level of confidence that a pest will be detected will provide a tool to help decision-makers to choose between different strategies, and to optimise the allocation of resources to different surveillance activities. The modellers in this project are working closely with researchers and regulators who understand the biology of the model pests...Project outcomes are expected to assist in the development of surveillance systems which achieve the required outcomes at the least cost. ”
