Some of the known threats to bumble bee populations include climate change, invasive species, habitat destruction, pollution, pesticides, and most significantly, the spread of diseases and pests through the commercial rearing of bumble bees. It’s hypothesized that the shipping of Bombus occidentalis and Bombus impatiens queens to European rearing facilities from 1992 to 1994 resulted in the acquisition of the microsporidian Nosema bombi , a virulent strain common in the European Bombus terrestris . The Nosema bombi fungus was found in a high number of the threatened bumble bee species. Research findings on the DNA of these species revealed that the bees have low genetic diversity which makes them more vulnerable to environmental pressures and other pathogens.
