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.
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 ...
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]
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
Acarapis woodi is a parasitic mite that infests the trachea that lead from the first pair of thoracic spiracles. An unidentified bee illness was first reported on the Isle of Wight in England in 1904, becoming known as the 'Isle of Wight disease' (IoWD), which was initially thought to be caused by Acarapis woodi when it was identified in 1921 by Rennie.
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.
The bees themselves might also help attract the beetle if they get into contact with the yeast pores released by nitidulids. The volatiles released by bees and the yeast together suggest the availability of the food and attract more beetles, which might lead to the absconding or the complete collapse of the hive. [4]
