A mystery about the bee colony collapse disorder (CCD) is dramatic, because for the last decade, scientist are working hard to find a reason and every time something about the theory was questionable.

Quick overview of research for the Bee Colony Collapse Disorder

Colony collapse disorder (CCD) is a mystery for a European honey bee colony disappearance, because bee colony is losing almost their entire adult bee population in a short time. The name CCD appeared in the year 2006,  with a drastic rise in the number of disappearances (30-90 %) of bees in North America.

Till today scientist said it`s probably because following reasons:

  • pesticides,
  • primarilyneonicotinoids,
  • infections with Varroa,
  • various pathogens,
  • genetic factors,
  • immunodeficiencies,
  • loss of habitat,
  • changing beekeeping practices or
  • a combination of factors (Wikipedia).

Did scientist finally solve the mystery of the bee colony collapse disorder?

According to the study published in article Rapid behavioral maturation accelerates failure of stressed honey bee colonies (Proceedings of the National Academy of Sciences) the reason for colony collapse disorder is in responses of individual (young) bees to stress.

A brief explanation of the problem

Typically, young honeybees have non stress assignments in the hive, until they come into adulthood. Only then, bees can leave the hive and begin foraging for nectar and pollen. Bees respond to many stressors by foraging nectar and pollen so it`s important that they are some way ready for this assignment, simply they have to be in adulthood.

But in this study by Clint J. Perrya, Eirik Søvika, Mary R. Myerscoughd, and Andrew B. Barrona, they discovered, that workers who begin foraging prematurely (due to external stressors) perform very poorly. So the problem is that the bees respond to many stressors (pests and pathogens, agrochemicals…) by foraging earlier in life. The result of that is the loss of almost the entire adult bee population.

The Bee Colony Collapse Disorder

It is sad to see an empty hive.

What is the solution for the bee colony collapse disorder?

However, if the real problem of the bee colony collapse disorder is known, the second question is, what is the solution to prevent CCD in the future, is it even possible?

We will inform you more about this news in the next days.
