The Bee Informed Partnership takes an annual survey of commercial and backyard beekeepers in order to track health and survival rates of honey bee colonies. The latest results show that colonies declined 44 percent during the year spanning April 2015 to April 2016.

There are three reasons why lazy journalists . . . are not only getting it wrong claiming pesticides are a cause, they are misrepresenting the data:
1) Surveys are not studies. Beekeeping has become a fad and that means a whole lot of amateurs have killed a whole lot of bees. . . .
2) They use both winter loss and summer loss combined. Lots . . . of bees die during the winter. . . so this combined number doesn’t have much validity because it hasn’t been gathered long enough – only six years. . . .
The real difference this year over last: 3.5 percent. In nature, that is statistical wobble.
3) . . . . The biggest culprit is the varroa mite, a deadly parasite that rapidly spreads spread between colonies but doesn’t show up in surveys. . . .
Though journalists are making this a pesticide issue, the scholars behind the work don’t.
“We’re now in the second year of high rates of summer loss, which is cause for serious concern,” Dennis van Engelsdorp, an assistant professor of entomology at the University of Maryland and project director for the Bee Informed Partnership, said in their statement. “. . . the fact that beekeepers are losing bees in the summer, when bees should be at their healthiest, is quite alarming.”
He said much the same thing last May, and implicated parasites. “Our biggest surprise was the high level of varroa. . . . Moreover, varroa’s ability to spread viruses presents a more dire situation than we suspected.”
