Honey bees at a hive entrance: one is about to land and another is fanning. Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees.

Dennis vanEngelsdorp is an associate professor [1] of entomology at the University of Maryland, College Park. He is the Chief Scientist for the Bee Informed Partnership and has been involved in a number of studies aimed at understanding colony collapse disorder.
The US Department of Agriculture indicated in a 2010 report to Congress that a combination of factors could be causing colony collapse disorder, including pesticides, pathogens, and parasites. Although pesticides were suspected to be part of the problem, a survey of healthy and CCD-affected colonies revealed similar levels of pesticides in wax ...
Varroa in combination with viral vectors and bacteria have been theoretically implicated in colony collapse disorder. [ citation needed ] It is known that thymol , a compound produced by thyme , naturally occurring in thyme honey, is a treatment for Varroa , though it may cause bee mortality at high concentrations.

Colony collapse disorder, a phenomenon involving the abrupt disappearance of honey bees in a beehive or Western honey bee colony centicandela (ccd), an SI unit of luminous intensity denoting one hundredth of a candela
Colony collapse disorder has attracted much public attention. According to a 2013 blog the winter losses of beehives had increased in recent years in Europe and the United States, with a hive failure rate up to 50%.
Varroa destructor, the Varroa mite, is an external parasitic mite that attacks and feeds on honey bees and is one of the most damaging honey bee pests in the world. [2] [3] A significant mite infestation leads to the death of a honey bee colony, usually in the late autumn through early spring.
