“eDNA-methods has opened the door for us to use innovative molecular techniques for detection of high priority insect pests and monitoring broader biodiversity (such as natural enemies of pests), even when species aren’t physically present at the time and undetectable with visual surveys.
EnviroDNA created opportunities for testing exotic species that are a major threat to the sugarcane industry using simple detection techniques that are easily deployable and useful for undertaking ongoing biosecurity monitoring and risk assessments.” - Dr Kevin Powell, Leader Entomology, Sugar Research Australia.

Biosecurity monitoring
Agriculture
The continued productivity, profitability, and growth of Australia’s agriculture industry relies on the ability to rapidly detect and contain exotic pest and disease incursions. Current biosecurity surveillance methods are arduous and time consuming, particularly in cases where monitoring over large areas is required. Scalable sampling approaches that are cost effective and sensitive using a combination of molecular techniques were trialled in this project. These methods use simple environmental sampling approaches to indirectly identify species that have recently been in an area, or to directly identify species that are difficult to identify by non-genetic methods.
This project utilised eDNA for rapid detection of pests threatening Australia's sugarcane industry, sampling in Queensland, Victoria, Papua New Guinea, and Indonesia. It tested eDNA methods on existing pests like Perkinsiella saccharicida and potential threats like Chilo spp. Results showed eDNA can indicate changes in species abundance over time and space, aligning with traditional monitoring methods. Plant wipes proved effective for detecting target species and assessing biodiversity, even when species are not visible. A rapid in-field molecular test for P. saccharicida provides results in 30 minutes, is cost-effective, and requires minimal equipment.
- Comprehensive approaches for pest monitoring
This project provides a comprehensive assessment approaches for multiple species of concern to the sugarcane industry showing that eDNA-based tools can offer both real-time, in-field detection of target species, as well as large-scale monitoring of taxa of interest. - Simplified ongoing deployment and training
These solutions are highly deployable, ensuring swift and seamless implementation. Additionally, staff have been equipped with the necessary training, knowledge and tools to conduct continuous assessments. This helps drive long-term success and sustainability.

We partner with agricultural clients to elevate biosecurity surveillance through innovative eDNA solutions. Our programs develop custom eDNA tests for invasive species, delivering rapid identification of invasive pests to help minimise the impact on crops. Additionally, eDNA soil health monitoring can help improve understanding of ecosystem health, so growers can gain insights that inform land management practices.
