An automated system that can deliver constant information about the condition of bees has been developed in Bulgaria. Beekeepers will be able to monitor data inputs from different hives via a remote control on diseases, contamination, temperature and noise levels. Bees can fly 30-40 times a day, and harmful substances in the air or on plants can easily contaminate the hive on their return. The scientists behind the device describe it as a means of ecological monitoring, with data capable of being stored for 20 years. Bees, which have been disappearing around the world, play a vital role, pollinating as many as 85% of the plants on the planet.
