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.
Potentially toxic effects studied in the laboratory have often been followed by field studies that fail to show effects on actual bee populations. [119] Despite gaps in the scientific evidence, regulators have restricted the use of neonicotinoids in Europe [120] and elsewhere [121] largely on the basis of concerns for bee health.
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]

Story at a glance New research underscores the negative effect of climate change on alpine bee populations. According to 60 years’ worth of data, bees in alpine regions are in an evolutionary ...
The Government has set out plans to end the use of three pesticides that are lethally toxic to bees and other vital pollinators. Neonicotinoids were banned in the UK in 2018, but have been ...
His research has led to significant breakthroughs in understanding and managing CCD, a primary cause of North American bee population decline. He is also known for discovering with Dennis vanEngelsdorp , then at Pennsylvania State University , the ability of bees to detect pesticides and harmful fungi in collected pollen and subsequently ...
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 ...
