Socially-acceptable eradication tools underpinned by modelling for eradication (BMSB, QFF, Codling moth, SWD)

Biosecurity outcome

• Feasibility of the sterile insect technique (SIT) and high-density mass trapping (HD-MT) for BMSB eradication known.
• The application and compatibility of multiple available eradication and delimitation technologies will be determined and optimised using population models for the eradication of BMSB, Queensland fruit fly (Qfly), great white butterfly (GWB) and codling moth (CM). CM parameters will inform an eradication model for Lobesia botrana (LB).
• Knowledge on the effect of eradication tool use on population viability via mate-finding (Allee threshold) for Qfly and Drosophila suzukii, SWD. Modelling approaches will support declaration of freedom of the aforementioned species, determine the best use of available tools and identify knowledge gaps.

Science outcome

• Determined whether the new tools of SIT and/or HD-MT are feasible for BMSB eradication.
• Developed and validated population models to determine optimal eradication tool timing, spacing and likely interaction with other control tools (e.g. insecticide, SIT and/or odour-based tools) for BMSB, Qfly, LB and GWB. PhD and MSc trained.

Key end users/stakeholders

Implementation:  Knowledge derived from the research will be used to inform GIA (industry/MPI) on the likelihood of success of each strategy.  Additional pre-operational funding may be required through B3 (or alternative source) but operational development/implementation would be the responsibility of the GIA.
