Managed honeybees and South American bumblebees exhibit complementary foraging patterns in highbush blueberry

Abstract Despite Apis mellifera being the most widely managed pollinator to enhance crop production, they are not the most suitable species for highbush blueberries, which possess restrictive floral morphology and require buzz-pollination. Thus, the South American bumblebee Bombus pauloensis is incr...
