This project was undertaken to better equip the Australian Brassica industry with knowledge of the current state of resistance levels in DBM field strains, and of the mechanistic processes that lead to the development of resistance, so that through this knowledge better insecticide resistance management (IRM) strategies may be devised.

This project has been funded by Hort Innovation, using the research and development levies listed below and contributions from the Australian Government. Hort Innovation is the grower-owned, not-for-profit research and development corporation for Australian horticulture.
