A single varroa mite has been detected in a sentinel beehive at the Port of Brisbane during a routine inspection by Biosecurity Queensland, prompting swift containment measures.
Diagnostic testing has confirmed the mite is Varroa jacobsoni, a parasite known to affect honeybees, rather than the more destructive Varroa destructor. Secondary testing is underway to determine whether the mite is carrying any exotic bee viruses or if other harmful pests are present.
In response, Biosecurity Queensland has launched tracing efforts to establish the potential source and risk of spread. Surveillance operations, conducted alongside the Queensland bee industry and the Australian Government, aim to determine whether additional varroa mites exist in the surrounding area.
A movement control order (MCO) has been enacted as a precautionary measure, restricting the movement of bees, hives, bee products, and used beekeeping equipment in and out of the affected area. The restrictions apply to beekeepers who have operated in the Port of Brisbane and nearby localities within the past 90 days.
Under the Queensland Biosecurity Act 2014, both Varroa jacobsoni and Varroa destructor are classified as prohibited matter, requiring immediate reporting if found or suspected. Beekeepers must also notify Biosecurity Queensland of any hive movements or bee sales within the past 90 days.
Queensland Agriculture Minister Mark Furner acknowledged the concern but emphasised the effectiveness of the state’s biosecurity response.
“This detection highlights the importance of our sentinel hive surveillance program,” Mr Furner said. “Queensland has successfully eradicated Varroa jacobsoni incursions in Townsville in 2016, 2019, and 2020, and we are confident in our ability to respond.”
Queensland Beekeepers Association president Jacob Stevens urged beekeepers to act swiftly.
“The Queensland Beekeepers’ Association stands ready to support affected apiarists,” he said. “We have successfully assisted in previous eradications and call on beekeepers to conduct immediate varroa mite surveillance and report findings via Bee 123.”
Beekeepers are encouraged to monitor hives using the alcohol wash method every 16 weeks, report any unusual hive deaths or deformed bees, and maintain accurate records of hive movements.
Those uncertain about the restrictions should contact Biosecurity Queensland at 13 25 23 before moving any beekeeping materials.
