March 2, 2026<\/strong><\/p>\n

Biosecurity Queensland has confirmed the detection of varroa mites in south-east Queensland with resistance to synthetic pyrethroid insecticides.<\/p>\n

A spokesperson said genetic testing by the Elizabeth Macarthur Agricultural Institute on February 24 identified mutations linked to resistance.<\/p>\n

Testing at several Queensland sites, including locations where treatment failure had been reported, confirmed reduced effectiveness of the pyrethroid Bayvarol.<\/p>\n

At this stage, the distribution of resistant mites appears limited.<\/p>\n

Further tracing and testing are underway to better understand the extent of spread and to guide management advice for industry.<\/strong><\/p>\n

This is the first confirmed case of pyrethroid-resistant varroa mite in Queensland. While spread appears limited at present, there is potential for further movement over time.<\/p>\n

Beekeepers have been urged to monitor their mite levels both before and after treatments to ensure mite populations have reduced.<\/p>\n

If they believe their treatment is not working, they should contact the DPI by email<\/a> <\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
