Improving management of chilli thrips in blueberry and Rubus (MT24009)

Improving management of leafrollers in rubus and blueberry 

Key research provider: NSW Department of Primary Industries and Regional Development

Project start date: 12/09/2025 

Project completion date: 29/06/2028 

This project targets the emerging issue of leafroller pests, orange fruit borer (OFB) and mango flower webworm (MFW), in the Australian rubus (raspberry and blackberry) and blueberry industries. Led by NSW DPIRD, the project will provide industry with effective monitoring tools and sustainable management practices. Activities include laboratory and field studies to better understand leafroller biology, host range, and seasonality, as well as the development of lures and pheromone blends for monitoring and mass trapping. 

The project will also explore biological control agents and develop an integrated pest management (IPM) pathway. Extension activities, field days, and industry publications will ensure findings are shared widely, enabling growers to adopt targeted, sustainable pest control practices and minimise economic losses from leafroller infestations. 

Improving management of chilli thrips in rubus and blueberry  

Key research provider: Murdoch University

Project start date: 20/05/2025 

Project completion date: 11/06/2028 

This project addresses the growing threat of chilli thrips, which are causing significant crop losses in Western Australia’s blueberry and rubus (raspberry and blackberry) industries. Led by Murdoch University, the project aims to develop more effective and environmentally friendly strategies for monitoring and managing chilli thrips. By improving understanding of the pest’s biology, lifecycle, and alternative hosts, the team will equip growers with better tools, including biological controls and integrated pest management (IPM)-compatible chemistries. 

Key outputs will include new pest monitoring tools, biological control agents, attractants, and practical guidelines for chilli thrips management. The project will also deliver training and extension resources to help growers implement these strategies, supporting improved yields, reduced crop losses, and more sustainable pest management across the industry.
