CoastLine: Honeybees, The Threats They Face, And Common Myths

The honey bee population declined slightly in the United States from 2016 to 2017.    That’s according to the U.S. Department of Agriculture.  The most-often reported colony stressor:  varroa mites. 

Colony collapse disorder, a separate phenomenon, also went up slightly from 2016 to 2017.   But the stressors that cause honey bees to die fall into roughly four categories, according to one of my guests today.  Colony collapse disorder is only one of those causes.   The notion that this little-understood phenonemon is decimating the honey bee population is only one of several often-repeated myths that seems to maintain traction.   

So what are the factors threatening honey bees?  They are largely parasites and pathogens, pesticides, and nutritional deprivation from habitat loss and the movement towards monocultures.  Loss of genetic diversity also plays a role.

But it’s nuanced:  while pesticides are killing bees, a recent study by scientists at the University of Texas at Austin suggests that the active ingredient in Roundup doesn’t directly kill bees.  But it harms their gut microbiome, which, as NPR reports, leaves them more susceptible to infection and death from harmful bacteria.
