Where has all the honey gone? Scientists point to factors in declining yields

Research has found that several factors have hampered bees' ability to create honey over the past decade

It's a question that has bedeviled beekeepers across the US in recent years: where has all the honey gone? Scientists now say they have some answers as to why yields of honey have declined, pointing to environmental degradation that is affecting all sorts of bees, and insects more generally.

The amount of honey produced by honeybee colonies in the US has dropped by around half a pound, on average, per colony in the past decade, US government data shows, even as the number of managed colonies increased slightly.
