The varroa mite is a parasitic mite that feeds on honey bees, with an infestation having the ability to lead to the death of an entire bee colony.

This has a significant impact on Australia’s honey and food production industry, with experts previously warning it could lead to losses of up to $1 billion over 30 years.

Varroa mite had previously been detected in New South Wales, Queensland, Victoria and the ACT, which has led to routine surveillance operations being conducted around the state to stop the spread of the dangerous pest.

South Australia has strict biosecurity to prevent the spread of varroa mite, including a requirement that imported hives must not have been within 25 kilometres of a known varroa outbreak.

The Department of Primary Industries and Regions confirmed yesterday that the hives from Queensland that carried the mite met the requirements and were not sourced from the vicinity of a known outbreak.

The state government said any beekeepers who have had hives within the radius of the outbreak should contact the PIRSA Biosecurity Apiary Unit. 

In addition, all beekeepers in the state are being urged to inspect their hives regularly with alcohol wash, sugar shake or sticky mat techniques.

“PIRSA’s Biosecurity Apiary Unit and Varroa Program Team, including the Varroa Development Officers (VDOs), are working closely with affected beekeepers to define the extent of the detection, slow the spread of varroa mite and help guide management practices”, a state government statement said.
