The key to breeding disease-resistant honeybees could lie in a group of genes—known for controlling hygienic behaviour—that enable colonies to limit the spread of harmful mites and bacteria, according to genomics research conducted at York University.
Some worker honeybees detect and remove sick and dead larvae and pupae from their colonies. This hygienic behaviour, which has a strong genetic component, is known to improve the colony's chance of survival. The researchers narrowed in on the "clean" genes that influence this behaviour to understand the evolution of this unique trait.

The finding, published today in the journal Genome Biology and Evolution, could lead to a new technique for use in selective breeding programs around the world to enhance the health of honeybees.
"Social immunity is a really important trait that beekeepers try to select in order to breed healthier colonies," said Professor Amro Zayed, a bee genomics expert in the Department of Biology, Faculty of Science. "Instead of spending a lot of time in the field measuring the hygienic behaviour of colonies, we can now try breeding bees with these genetic mutations that predict hygienic behaviour."
Statistics - Canada - Honeybee - Pollination - Year
Statistics Canada estimates that honeybee pollination contributes between $3.15 to $4.39 billion per year to the Canadian economy including some of Canada's most lucrative crops like apples, blueberries and canola. In Canada, and around the world, beekeepers have experienced higher than normal colony losses. Last winter, Canadian beekeepers lost up to 33 per cent of their colonies.
