Tiny lasers placed in beehives could be an effective way of fighting parasitic pests, researchers say.
Scientists at the University of Auckland’s Photon Factory are currently working with Plant and Research to devise a way of protecting honey bees without using pesticides.
The pests in question are Varroa mites, which cling to bees as they enter their hives – infesting them and leaving “critical damage”.
Varroa mites feed on bees, larvae and pupae, spreading diseases and can cause entire colonies to collapse.
Given bees' role in prop pollinating, varroa mites are a major threat to food security worldwide.
A unique solution is now being proposed, with scientists suggesting tiny lasers could be placed at hives entrances, targeting mites.
One of the researchers, Dr Francesco Merola, said: “Our goal is to free bees to do their important agricultural work by allowing beehives to thrive again, to be more resilient, healthy homes for bees.”
Merola will be testing different lasers in a containment lab in Hamilton to see their effectiveness on the mites.
The project's other lead, Professor Cather Simpson, said: “It’s an ambitious project which will make a difference all over the world if we’re successful.”
The team has been given a $1 million grant from the Ministry of Business Innovation and Technology.
They hope to complete research in the next two years – and potentially roll out the project in five.
“Challenges will include creating a device easy to fit to the hive which bees are happy to move through,” a statement reads.
It’s hoped the device will be used by beekeepers around the world.
