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.
Honey bee starvation is a problem for bees and beekeepers.Starvation may be caused by unfavorable weather, disease, long distance transportation or depleting food reserve. Over-harvesting of honey (and the lack of supplemental feeding) is the foremost cause for scarcity as bees are not left with enough of a honey store, though weather, disease, and disturbance can also cause problem

Turns out, it may be pretty easy. "Plant lots of wildflowers! Bees need wildflower pollen and nectar to stay happy and healthy, so planting wildflowers is a fun, easy way to help the bees," the ...
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 ...
Bees infected with CBPV begin to show symptoms after 5 days and die a few days after. [1] Chronic bee paralysis virus infection is a factor that can contribute to or cause the sudden collapse of honeybee colonies. [2] Since honeybees serve a vital role in ecological resilience, it is important to understand factors and diseases that threaten them.
