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.

Beekeeping in Mongolia has a short history, with several species and subspecies of managed honey bees having been introduced in Mongolia since 1959. Introduced and managed species include the European dark bee, the Caucasian honey bee, the Russian Far East bee (Apis mellifera carpatica), and the "Haliun" bee that resulted from crossbreeding three geographically distinct honey bee species.

Globally declining bee populations threaten agricultural production and food security. [9] In the United States, beekeepers reported that they lost 45 percent of colonies in the year from April 2020 to April 2021. [4] Factors involved in population decline are complex and interrelated. [10] One of the areas Grozinger has studied is nutrition.
The presence of varroa mites results in a decrease in bee population, deformed bees, an inability to reproduce on the bees part, and overall weakening of the colony. Varroa mites are only capable of reproducing inside of a honey bee colony, posing an even greater threat if they are able to infiltrate because it will destroy their home.
