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.

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.
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 ...
Census data shows that the number of bee colony operations rose much faster than honey production—and is up 160% since 2007. Pollination—not honey—is why the U.S. needs more bees
Colony collapse disorder (CCD) is a poorly understood phenomenon in which worker bees from a beehive or western honey bee colony abruptly disappear. CCD was originally discovered in Florida by David Hackenberg in western honey bee colonies in late 2006. [77]
For some insect groups such as some butterflies, moths, bees, and beetles, declines in abundance and diversity have been documented in European studies. These have generally led to an overall pattern of decline, but there are variable trends for individual species within groups. For instance, a minority of British moths are becoming more common ...
The blackness on the bee on the right is a symptom of CBPV. Chronic bee paralysis virus (CBPV) commonly affects adult Apis mellifera honey bees and causes a chronic paralysis that can easily spread to other members of a colony. Bees infected with CBPV begin to show symptoms after 5 days and die a few days after. [1]
David Hackenberg is an American commercial beekeeper [1] [2] who started Hackenberg Apiaries which runs beehives in several American states.. Hackenberg witnessed the first case of what was going to be known as Colony Collapse Disorder (CCD) in November 2006 and reported it publicly in February 2007.
