A VOODOO field experiment by researchers at MLU in Halle shows that commercially-sourced bumble bees (Bombus terrestris) suffer greater mortality when experimentally infected by injection with Deformed Wing Virus (variant A) than when fed the virus, as might be the case when they feed on flower pollen and nectar.  For more see our library and the paper . This highlights the need to understand better the mode of viral transmission and infection among species and to examine other impacts on bumble bee performance, especially colony fitness, to broaden our understanding of the consequences of DWV spillover from managed bees to other pollinators.
