Bee colonies are dying out worldwide and nobody is exactly sure why. The most obvious culprit is the Varroa mite which feeds on bees and bee larvae, while also spreading disease. The only country without the Varroa mite is Australia. However, experts believe that there are many factors affecting bee health.
To unravel this, CSIRO is leading the Global Initiative of Honeybee Health (GIHH) in gathering large sets of data on bee hives from all over the world. High-tech micro-sensor ’backpacks’ are fitted to bees to log their movements, similar to an e-tag. The data from individual bees is sent back to a small computer at the hive.
Researchers are able to analyse this data to assess which stressors – such as extreme weather, pesticides or water contamination – affect the movements and pollination of bees.
Maintaining honey bee populations is essential for food security as well securing economic returns from crops. Bee crop pollination is estimated to be worth up to $6 billion to Australian agriculture alone.
Currently 50,000 bees have been tagged and there may be close to one million by the end of 2017. Researchers aim to not only improve the health of honey bees but to increase crop sustainability and productivity through pollination management.
