This project developed and delivered targeted R&D specifically for serpentine leafminer in response to the incursions detected in late 2020.
The project built on the initial work of the RD&E program for control, eradication and preparedness for vegetable leafminer (MT16004).
Areas of work included:
- Identifying and monitoring parasitoids
- Refining development and validation of surveillance and diagnostic protocols
- Using predictive forecasting to manage and assess the risk of serpentine leafminer
- Delivering an industry communication program
- Developing an industry management plan, grower guides and industry focused workshops
The project
Serpentine leafminer (SLM – Liriomyza huidobrensis) is a previously exotic insect pest with the potential to significantly impact a wide range of commercial crops (vegetables, broadacre, ornamentals and non-commercial hosts) and is categorised as a high priority pest in the vegetable and potato industry biosecurity plans. It was first detected in Australia in Western Sydney NSW in October 2020 and soon after in the Fassifern Valley, QLD in November 2020. There have since been further sightings in Southeast QLD.
The inclusion of serpentine leafminer into the recently completed project RD&E Program for control, eradication, and preparedness for vegetable leafminer (MT16004) has enabled a rapid response to these incursions in facilitating industry understanding of the significance of this pest to the vegetable industry.
MT20005 built on the initial work undertaken in MT16004 by refining development and validation of tools, including surveillance and diagnostic protocols, predictive forecasting for SLM risk assessment and management, as well as identifying and monitoring parasitoids, and delivering an industry communication program including the development of industry management plan, grower guides, and industry focused workshops.
AUSVEG’s role
AUSVEG delivered the communications and engagement component of the program, facilitating workshops and delivering educational materials to growers and the wider horticulture industry, including regional biosecurity/extension agents.
AUSVEG also developed an industry management plan for SLM and four commodity grower guides for vegetables, potatoes, onions, and melons for industry use.
