The key to queen bees’ hearts may be through their stomachs and a research team at the University is on the case.
About a third of queen bees fail to survive an Ontario winter and it might be because of the microflora in their guts, the researchers led by Brendan Daisley speculate.
Beekeepers import replacement queen bees from countries such as the United States, Chile and Italy and their digestive systems have evolved to suit a different environment, so that may be the reason so many die.
The Canadian Beekeepers Association has noticed and encourages its members to keep as many domestic queen bees as possible.
Now it is supporting the Canadian Bee Gut Project.
As part of the research the team is collecting data about the microbiome profiles of thousands of bees from across Canada.
They are looking into how those gut profiles differ in their support of digestion, immune system regulation and countering harmful bacteria.
They have already found that domestic bees have microbiomes that support those systems and are at least a big part of why their survival rates are better than the imported queen bees..
"We're trying to better understand how the microbiome impacts overwintering success," said Daisley, who is a postdoctoral fellow at the University of Guelph.
Canadians import about 300,000 queen bees per year and they build colonies that are a mismatch with Canada's forage, pathogens and seasonal stressors, Daisley told CBC Radio in Kitchener.
"Their genetics have evolved to be most suited to warmer climates so when they come here, their offspring, the worker bees, are not adapted to colder climates and to surviving the winter,” he said,
