Virion structures and genome delivery of honeybee viruses

•Infections by dicistroviruses and iflaviruses are lethal for honeybees.•Capsids of dicistroviruses and iflaviruses are organized with icosahedral symmetry.•Genome release of honeybee viruses is induced by acidic pH.•Minor capsid proteins or protruding domains enable honeybee viruses to penetrate host membranes.
