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.
This social parasite is native to 15 states across the U.S. and obliges other bee species to raise its offspring. However, Suckley’s cuckoo bumble bees A New Law Protects Two Beloved Species ...
[6] [65] While noting population increases for certain species of insects in particular areas, the authors reported an annual 2.5% loss of biomass. They wrote that the review "revealed dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over the next few decades", [6] [66] a conclusion that was challenged.
Others move from Florida to New Hampshire or to Texas. About two thirds of US domestic bees visit California for the almond bloom in February. California currently leads production of almonds worldwide, with 80% of global production. Each spring, migratory beekeepers rent hives to almond farmers in the Central Valley for pollination.

With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
