The Hivesite team, made up of father and son Alistair and Gareth Bell – alongside James Emslie and Vijay Prema – have developed an in-hive treatment that autonomously uses heat treatment to destroy the Varroa mite.

Originally, the team set out to detect the mites in a colony using camera and artificial Intelligence. However, they quickly realised that finding a solution to break the life cycle of the infestation was a more important path to follow.

Their solution, which avoids the use of pesticides that can decrease honey production, consists of a solar powered heater panel located under the brood zone of the hive. The heating element delivers a temperature of 39 to 45 degrees C to the area, killing the mite, but not the bees – which already use temperature to protect themselves.

An integral micro-processor automatically raises the temperature in the hive every three weeks for a period of two hours, to coincide with the 21 days it normally takes a bee to gestate from an egg to an adult.

In the case of the mites, one foundress or female can create seven offspring –usually found in the brood area.

These are destroyed at an early stage by the heat, thereby breaking the breeding cycle of the pest.

With one solar panel able to power four, 10-frame Langstroth hives, the system is particularly suited to commercial operators – particularly those operating in remote areas.
