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.
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
Colony losses were also reported in five Canadian provinces, several European countries, and countries in South and Central America and Asia. In 2010, the United States Department of Agriculture reported that data on overall honey bee losses for 2010 indicated an estimated 34% loss, which is statistically similar to losses reported in 2007 ...
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]

Although historical data for insect distribution is sparse in western North America, it is clear that Bombus vosnesenskii is not experiencing a population decline; it is amongst the most common bee species on the West Coast of the United States, and the most common bumble bee from Oregon northward.

[7] [8] He was the research leader at the United States Department of Agriculture's Beltsville Bee Laboratory (BBL). [2] His research has led to significant breakthroughs in understanding and managing CCD, a primary cause of North American bee population decline.
No longer were people chalking it up to bad beekeeping; everyone was experiencing the same rapid, catastrophic declines in hive populations in 35 states. And no one could explain why. The theories ...
