What is Collapse Disorder Beehive?

The bees are essential pollinators for ecology and agriculture. In recent years there has been a mysterious problem called Collapse Disorder Hive (CCD, for its acronym in English).

Colony collapse disorder, the colony collapse disorder, bees collapse syndrome, syndrome depopulation of beehives

The bees can die from many causes, but the collapse disorder Hive is distinguished by the following strange features

The sudden disappearance of the vast majority of worker bees.

The absence of bodies of dead bees around the hive (worker bees simply “disappear”).

The queen is alive and active within the hive, along with immature bees.

The hive has relatively abundant reserves of honey and pollen.

The lack of an obvious cause for the death or disappearance of bees.

Other causes of sudden death in hives include epidemics of diseases or parasites and contact with pesticides. Unlike Collapse Disorder Hive in cases of pesticide poisoning epidemics and bees die near the hive, resulting in piles of dead bees at the entrance or around the hive.

It is normal for hives population down somewhat during the winter. However, in recent decades beekeepers have been slightly exaggerated reduction of wintering populations of their hives. Finally, during the winter of 2006-2007, beekeepers began noticing a much higher than normal decline. Some beekeepers reported losses of between 30 and 90% of the hive, with up to half of them without any known cause. This mysterious problem lit a warning light for everyone and prompted a call to action to save bees. Since 2007 the situation has improved somewhat, but the collapse disorder Hive is still a big threat to bees and to date do not fully understand its causes.

Although it is not known exactly what Collapse Disorder Beehive is due, the general consensus is that it is a combination of the following factors

Exposure to toxic pesticides.

new diseases such as Israeli Acute Paralysis Virus.

Parasites such as the Varroa mite.

Loss of their natural habitat.

Lack of quantity and / or variety of foods.

Pollution of vital resources such as water.

stressful for bees to be the handling and transportation of the hive from field to field for fertilization of different crops, poor hive management resulting in congestion or overcrowding, and inadequate access to water factors.

When the hive is stressed, it becomes more susceptible to diseases and parasites. The most likely to cause colony collapse is a set of several adverse factors. To avoid it is necessary to remove chemical pollutants and improve management of hives.
