Fewer colony losses occurred in the US over the winter of 2013–2014 than in recent years. Total losses of managed honey bee colonies from all causes were 23.2% nationwide, a marked improvement over the 30.5% loss reported for the winter of 2012–2013 and the eight-year average loss of 29.6%. [33]
Nearly a million bee colonies have been formed in the past five years, according to 2022 Census of Agriculture data from the USDA, boosting the total number of colonies to an all-time high of 3.8 ...
Deformed bees are rapidly expelled from the colony, leading to a gradual loss of adult bees for colony maintenance. If this loss is excessive and can no longer be compensated by the emergence of healthy bees, the colony rapidly dwindles and dies. [citation needed]
The picture for domesticated pollinator species is less clear. Although the number of managed honey bee colonies in Europe and North America declined by 25% and 59% between 1985-2005 and 1947-2005 respectively, overall global stocks increased due to major hive number increases in countries such as China and Argentina.
The study delved into the impacts of climate change on honey bee colony dynamics, particularly focusing on the Pacific Northwest. Warmer autumns, winters pose threat to PNW honey bee survival, WSU ...

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]
Backyard beekeepers face more colony losses in the winter than in the summer, but for commercial beekeepers there is not much variation in loss by season. [2] Roughly 22% of backyard beekeepers have identified starvation as one of the main causes for colony losses. [3] Honey bee starvation is an especially challenging problem for beginning ...
