Bumble bees are expert pollinators of several crops
Although this kinds is actually earlier aren’t discover compliment of the majority of their range, surveys between 2003 and provide have found few B. affinis. Has just, B. affinis has been discovered in short amounts from inside the isolated areas pri that it varieties try listed as threatened according to the U.S. Threatened Varieties Act.

Ranging from 1992 and you will 1994, queens from B. occidentalis and you can B. impatiens was in fact brought to Western european rearing facilities, where territories was introduced after that mailed to the latest You.S. getting commercial pollination. Bumble-bee specialist Robbin Thorp has actually hypothesized why these bumble-bee territories gotten a condition (probably an excellent virulent variety of the latest microsporidian Nosema bombi) off an excellent Eu bee that has been in identical rearing studio, the brand new Lover-tailed Bumble bee (Bombus terrestris). Dr. Thorp hypothesized that disease following wide spread to crazy communities from B. occidentalis and you may B. franklini throughout the Western (of contact with infected populations away from commercially reared B. occidentalis), and B. affinis and you may B. terricola in the East (of contact with theoretically reared B. impatiens). Throughout the later 1990’s, biologists started initially to see that B. affinis, B. occidentalis, B. terricola, and you may B. franklini was basically really declining.
