New Aussie technology and funding could halt one of the 21st century’s most troubling trends: the sudden decline in bee populations around the world.

The problem, which started making headlines about 15 years ago, is serious because honey bees pollinate* one third of the food we eat each day. The contribution they make to Australian agriculture* alone has been valued at between $4-$6 billion.

Now cheesemaker Bega is exploring a possible solution as it pushes into the $100 million Australian honey market.

Dubbed the Purple Hive Project, the company will use 360-degree cameras and artificial intelligence* to scan bee colonies for the Varroa mite, which has caused the collapse of bee populations around the world.

The technology will scan each bee in a hive, and if the mite is detected, an alert will be triggered, enabling it to be quickly quarantined*.

The mite has not yet taken hold in Australia, apart from one small infestation* in Townsville in 2016, but its arrival in New Zealand in the early 2000s strengthened efforts to monitor bee colonies here.

Ian Cane, a third generation beekeeper from Bairnsdale in Victoria, said the fact the mite had been largely kept out of Australia so far was partly good surveillance* and partly good luck.

“We’re the only continent on earth now where the bee populations are not subjected* to this parasite,” he said.

He said Australia’s production of honey and foods that result from pollination would drop significantly if the mite got in.

He warned Australia’s climate, particularly in the tropical north, made it vulnerable* to the mite.

He said bees had babies more often the further north you went in Australia and this would give the mite more chance to breed.

“So we think it would have a devastating impact in that sense,” Mr Cane said.

Bega Foods executive general manager Adam McNamara said the technology was being tested in Australia using “artificial Varroa” and in New Zealand using the real thing.

“The ability to detect and then ultimately manage Varroa we believe is just a massive step forward for the industry,” he said.

Bega recently launched its 100 per cent Australian made B Honey range, part of a growing range of products for the company that now also includes peanut butter and Vegemite.
