Genetics is a powerful tool in our fight against fire ants. By monitoring fire ant DNA profile across our operational area, our scientists can map local populations and detect unusual arrivals.
When fire ants are detected in unexpected locations – like ports or shipping containers – their DNA profile is compared with local colonies, historic infestations, and international datasets.
A different genetic profile from that of the current infestation indicates a new incursion rather than spread from the existing infestation in South East Queensland.
This scientific approach helps us:
- pinpoint the likely origin of new detections
- distinguish local spread from new incursions
- confirm successful eradication
- strengthen biosecurity measures to prevent further spread.
Genetic analysis has been key in identifying and successfully eradicating 8 of the 9 fire ant incursions detected in Australia.
Understanding how fire ants move also allows rapid, targeted responses, protecting communities, businesses, and industries from their devastating impacts.
