Colony Collapse Disorder

Colony Collapse Disorder is the single biggest threat currently faced by honeybees. Beekeepers first started to report the sudden disappearance of bees from their hives in 2006 in the Eastern United States. Over the last 3 years, CCD has killed over one in three bee colonies in 35 states across the US. In some cases, up to 90% of bees have been lost, and the problem is now worldwide – there have been losses reported in both Europe and Asia.

So, what are the symptoms and causes of colony collapse disorder? The main symptom of CCD is simply no or a low number of adult honey bees present but with a live queen and no dead honey bees in the hive. Often there is still honey in the hive, and immature bees (brood) are present.

Symptoms of Colony Collapse Disorder

  1. An almost overnight disappearance of virtually all the worker bees – within a few days, previously thriving well established colonies lose almost all of its adult bees. Unlike other diseases or infestations, there are no dead bees to be found. They simply leave the hive and never come back.
  2. The queen and a small number of very young bees, just hatched, remain and these tend the queen. You know they are young as they are light colored and still fuzzy.
  3. Lots of honey and pollen still in the hive, and also a lot of brood left behind.

Normally when a colony dies or is abandoned, scavengers (like ants, small hive beetles, and wax moths) very quickly come in and steal the honey, dead bees, or pollen that has been left behind. But with CCD, the anecdotal evidence is that this does not seem to happen. Other creatures stay away from the hive. No-one knows why, but it does suggest that they somehow instinctively sense that it is contaminated and so stay clear.

Causes of Colony Collapse Disorder

Causes are largely still unknown, but there are several main suspects. There is one theory that cell phone masts may be scrambling bees’ navigational systems. While this has not been completely ruled out, recent research has failed to find any evidence of a link. Most experts believe the cause of colony collapse disorder is more likely to be related to parasites (particularly Varroa and Tracheal mites), disease (especially Nosema) or pesticides.

Each individual beekeeping parasite and disease, while often damaging, is not thought to be sufficient to cause colony collapse disorder. In colonies affected by CCD, scientists found some evidence of infestation or infection, but no more so than in colonies without CCD.

More attention is now turning to chemicals. An analysis by Penn State researchers of beehive wax has shown very high levels of pesticides used by beekeepers in the hives to combat Varroa mites – particularly fluvalinate and coumapho.

The researchers also found lower levels of 70 other pesticides, not used by beekeepers but by farmers on agricultural crops. These were also present in pollen and in the bees themselves.

And particularly worrying is the interaction between these different chemicals. For example, initial research has found that some combinations of fungicides and insecticides can be a 100 times more toxic than any of the chemicals individually.

Whether these pesticides are a contributory factor to CCD is still unclear, but they are definitely stressors. One theory is that the combination of pesticides with the other existing stressors (parasites and disease) together cause the perfect storm, and hence colony collapse disorder.

Whatever the cause, CCD is a serious threat both to bees and to our food supply. The one positive is the increased public awareness of the crucial role that bees play. Hobby beekeeping has never been so popular, which can only be good – the more people who start beekeeping, the better the chance of survival for the honey bee.

So, yet another good reason to get out there, and start beekeeping.

Welcome to the BestBeekeeping Blog.

Bees are fascinating creatures, and here we’ll look at all things beekeeping – why keep bees, what you need to start beekeeping, diseases and other issues to watch for, honey and other bee products and their uses …. the list is almost endless!

Beekeeping has never been more popular, but paradoxically bees have never been more at risk

Bees are under serious threat from pests like the Varroa mite, diseases like American Foulbrood or European Foulbrood, and more recently from Colony Collapse Disorder (or CCD).

Of course the revived interest in beekeeping is partly because of the increased media interest caused by these threats. People are more aware of how important bees and beekeeping are for our food supply (one third of everything we eat depends on pollination, and 80% of all pollination is done by honey bees).

But I believe beekeeping is also rising in popularity because more and more people are beginning to realize that just maybe there is more to life than work, money, material possessions… and then some more work.

Bees and beekeeping have a unique power to allow you to switch off from the pressures of everyday life, to de-stress and unwind.

From the outside, it looks like mayhem. 60,000 bees buzzing about their hive in a seemingly bewildered and incoherent way. But each one has a specific job to do, and together they accomplish more every day than you could possibly believe.

Fascinating is a word that is probably overused when it comes to describing bees, but they really are fascinating .

You are reading this, so you are obviously interested in bees and beekeeping. So stay tuned, we’ll be posting to the blog very often. If you have any questions or suggestions we’d love to hear them, so please leave a comment below, or email us.
