Scientists make 'superfood' that could save honeybees
Scientists have developed a honeybee ‘superfood’ that could protect the animals against the threats of climate change and habitat loss. Bee colonies that ate the supplement during trials had up to 15 times more baby bees that grew to adulthood. Honeybees are a vital part of food production and contribute to pollinating 70% of leading global crops. "This technological breakthrough provides all the nutrients bees need to survive, meaning we can continue to feed them even when there's not enough pollen," senior author Professor Geraldine Wright at the University of Oxford told BBC News. "It really is a huge accomplishment," she says.
Honeybees globally are facing severe declines, due to nutrient deficiencies, viral diseases, climate change and other factors. In the US, annual colony losses have ranged between 40-50% in the last decade and are expected to increase. Beekeepers in the UK have faced serious challenges too. Nick Mensikov, chair of the Cardiff, Vale and Valleys Beekeepers Association, told BBC News that he lost 75% of his colonies last winter and that this has been seen across South Wales. "Although the hives have all been full of food, the bees have just dwindled. Most of the bees survived through January, February, and then they just vanished," he says.
Prof Wright says the food would be particularly useful during summers like this one when flowering plants appear to have stopped producing early. "It's really important in years when the summer comes early and bees will not have sufficient pollen and nectar to make it through the winter," she says. "The more months that they go without pollen, the more nutritional stress that they will face, which means that the beekeepers will have greater losses of those bees over winter," she explains. Larger-scale trials are now needed to assess the long-term impacts of the food on honeybee health, but the supplement could be available to beekeepers and farmers within two years. The study was led by the University of Oxford, working with Royal Botanic Gardens Kew, University of Greenwich, and the Technical University of Denmark.
