Emerging infectious diseases (EIDs) pose a risk to human welfare, both directly1 and indirectly, by affecting managed livestock and wildlife that provide valuable resources and ecosystem services, such as the pollination of crops2. Honeybees (Apis mellifera), the prevailing managed insect crop pollinator, suffer from a range of emerging and exotic high-impact pathogens3, 4, and population maintenance requires active management by beekeepers to control them. Wild pollinators such as bumblebees (Bombus spp.) are in global decline5, 6, one cause of which may be pathogen spillover from managed pollinators like honeybees7, 8 or commercial colonies of bumblebees9. Here we use a combination of infection experiments and landscape-scale field data to show that honeybee EIDs are indeed widespread infectious agents within the pollinator assemblage. The prevalence of deformed wing virus (DWV) and the exotic parasite Nosema ceranae in honeybees and bumblebees is linked; as honeybees have higher DWV prevalence, and sympatric bumblebees and honeybees are infected by the same DWV strains, Apis is the likely source of at least one major EID in wild pollinators. Lessons learned from vertebrates10, 11 highlight the need for increased pathogen control in managed bee species to maintain wild pollinators, as declines in native pollinators may be caused by interspecies pathogen transmission originating from managed pollinators.
“When California was wild, it was one sweet bee garden throughout its entire length,
north and south, and all the way across from the snowy Sierra to the ocean.”

Welcome to the Los Angeles County Beekeepers Association, founded in 1873, to foster the interest of bee culture and beekeeping within Los Angeles County. Our primary purpose is the care and welfare of the honeybee. Our group membership is composed of commercial and small scale beekeepers, bee hobbyists, and bee enthusiasts. So whether you came upon our site by design or just 'happened' to find us - we're glad you're here! Our club and this website are dedicated to educating our members and the general public. We support honeybee research, and adhering to best management practices for the keeping of bees.
