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.

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. [2]
A dead carpenter bee Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
To be sure, the era of bee colony collapse is still not behind us. Many factors, like climate change, are big threats. Global warming means the autumn season is longer and hotter, ...
Here’s a bummer of a statistic for you: Around 30% of bee colonies disappear every year. Scientists coined the phrase "colony collapse disorder" (CCD) to describe what’s been a devastating ...
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.
A new study suggests that the mysterious disappearance of the Earth's bees may be in part because they are developing dementia. According to the new research dementia caused by aluminum found in ...
Bees die far away from the dwellings, as when they leave they are too weak to return. This leads to collapse of the bee colony. Within a few years, a strongly increased propagation of Nosema was observed, and its occurrence was happening all year round due to the higher resistance of N. ceranae. A higher reinfection rate of the bee colonies is ...
