Schematic showing the potential presence in bumblebees of components from the major described pathways in honeybee immunity that are implicated in the defence against bacterial, fungal and viral pathogens (schematic adapted from [48]). Shaded and bold outlined components indicate this component from either Apis mellifera or Drosophila melanogaster is "hit" by a sequence in the Bombus terrestris EST library.
