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.
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.

The decline was "apparent regardless of habitat type" and could not be explained by "changes in weather, land use, and habitat characteristics". The authors suggested that not only butterflies, moths and wild bees appear to be in decline, as previous studies indicated, but "the flying insect community as a whole". [1] [4] [52] [53] [54]
However, Suckley’s cuckoo bumble bees This social parasite is native to 15 states across the U.S. and obliges other bee species to raise its offspring. A New Law Protects Two Beloved Species ...
A decline in bee population leads to a decline in crop yield, which will then result in a reduction in the food supply and cause economic hardships for farmers. [24] [25] Commercially produced B. impatiens is one of the most important species of pollinator bees that are used by greenhouse industry in North America, [7] including Canada and ...

[9] [10] She is particularly well known for her work breeding lines of honey bees that detect and quickly remove diseased larvae and pupae, which is called hygienic behavior. [ 11 ] [ 12 ] Spivak has extensively studied the causes and impacts of Colony Collapse Disorder (CCD), a phenomenon where honey bee hives are abandoned by their worker bees.
Officials say the loss and degradation of breeding, migratory and overwintering habitat; exposure to insecticides; and the effects of climate change have all contributed to the populations' decline.
