Status: In Progress

Start date: 1 July 2021

Completion date: 30 June 2024

Project code: A-030

Species: Mice

Summary

Current invasive mammal pest management is based on several management techniques including baiting, trapping, fencing and for rabbits; viral biocontrol. Many of these methods rely on costly sustained resources to accomplish a reduction of impacts. There are currently no effective management landscape options for devastating mouse plagues
Gene drive is a technology that aims to manipulate reproductive processes to disseminate a gene across a population. In terms of biocontrol, the gene selected would suppress the rate of reproduction and thus the overall spread and impact of the pest population.

Key achievements

Outputs

  • A genetic biocontrol strategy for the suppression of mice.
  • Demonstrated ‘proof of concept’ that could be used to suppress invasive vertebrate populations in Australia.
  • An online analytical tool to assess the feasibility and risk of deploying gene drive technologies.

Outcomes

  • World-first breakthrough genetic biocontrol technology for Australia.
  • Key technology for the fight against mouse plagues in Australia.
