A bumblebee and honeybee collect sunflower nectar. Efficient pollination is vital for both crop production and ecosystem sustainability, and there is evidence to suggest that emerging infectious diseases are contributing to a decline in populations of some important insect pollinators. This study combines laboratory infection experiments and field studies to demonstrate infectivity of two serious honeybee (Apis mellifera) pathogens in a wild pollinator, the bumblebee (Bombus terrestris). Data from across the United Kingdom show that there is co-localization of deformed wing virus (DWV) and the microsporidian parasite Nosema ceranae in the two types of pollinator, and that the honeybee disease can be infectious in bumblebees. This work indicates that wild pollinator populations may be at risk, and unlike managed populations of Apis, they are not protected by intervention from beekeepers. Such a loss of wild pollinators would significantly decrease crop pollination efficiency. Cover Paul Maguire/Alamy.
