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
This series explores aspects of America that may soon be just a memory -- some to be missed, some gladly left behind. From the least impactful to the most, here are 25 bits of vanishing America ...
Insects with population trends documented by the International Union for Conservation of Nature, for orders Collembola, Hymenoptera, Lepidoptera, Odonata, and Orthoptera. A 2020 meta-analysis found that globally terrestrial insects appear to be declining in abundance at a rate of about 9% per decade, while the abundance of freshwater insects appears to be increasing by 11% per decade.
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.
