> the idea that improved beekeeping management might be responsible for much of the increased virulence seen with EFB.
Recent publication correlates intensive management with lower overall losses:
> According to the data that are freely available on the beeinformed.org website, winter mortality differed by operation size; backyard beekeepers lost an average of 45.5% of their colonies over the winter of 2016–2017, while sideliners lost 37.2%, and commercial beekeepers lost only 25.6%. These results about winter mortality indicate that colony survival is affected by management practices.

> 14,813 beekeepers providing valid loss data collectively wintered 425,762 colonies ... The overall analysis showed that small operations suffered higher losses than larger ones.
