Varroa mite in Australia forever after eradication deemed no longer possible

The National Management Group confirmed on Wednesday eradication of Varroa destructor was "no longer feasible based on technical grounds" and will now transition to a management strategy.

While a revised response plan, including transition to management activities, is being developed, NSW will operate under an interim strategy to limit the impacts and slow the spread of varroa mite.

For more than 12 months, the hive-collapse causing parasite had been restricted to a 10,000-square-kilometre patch of NSW, with Newcastle at the epicentre.

Up until June, it was believed Australia still had a chance to become the first country in the world to eradicate Varroa mite.

However, things quickly changed in August, when the pest was discovered in hives in Kempsey. Further related detections were found in the Riverina and Sunraysia region, just kilometres from the Victorian border.

Australian Honey Bee Industry Council chief executive Danny Le Feuvre said the news would change beekeeping forever.

"No one wants varroa mite - we gave it our best shot to eradicate it, but the size, complexity and cost of the response was too great to continue with," Mr Le Feurve said.

More than 30,000 hives, holding up to one billion bees, were destroyed in the eradication process.

Managing the pest will impose more costs on beekeepers. Although it's not expected to increase shelf prices, Mr Le Feurve said the price would have to be absorbed somewhere.

"The mite won't spread as quickly as COVID, we have got time to learn and adapt," he said.

"Every other country in the world lives with varroa mite and beekeepers do manage it everywhere else, so there are lessons to be learnt there."

Colony loss will be an ongoing concern, with the United States reporting 48 per cent of colonies lost annually, while New Zealand reported 13pc.

There is yet to be a Victorian infestation confirmed, however dozens of hives are within emergency surveillance zones and are prohibited from moving.

More than $100 million was spent in an attempt to eradicate the pest.

The NGM blamed the strategies failure on several reasons including some beekeepers illegally moving hives. The recent spike in detections also made it clear the infestation was more widespread and had been present for long than first thought, and stretched the eradication team's resources to their technical limit.
