These proteins are associated with uncapping brood cells and the removal of larvae. Other proteins are involved in the process of smelling and in signal transduction /wiki/Signal_transduction In damaged larvae, transglutaminase, a protein involved in blood clotting, increases the response to a stimulus. These proteins are also found in the antennae of adult honey bees. Scientific research in a journal published by BioMed Central Ltd, discovered that honeybee larvae, which have been parasitized by the mites and are often diseased, contain specific proteins. The parasitic mite Varroa destructor is a major contributor to the death of honey bee colonies. There may be a lesson here for domestic beekeepers because now we know that this is a characteristic worth promoting because it seems to offer the bees some natural defence. Domestication of honey bees has resulted in a reduction of resin collection, likely because beekeepers have selected against its use since the presence of large quantities of sticky propolis often makes opening hives more difficult. Resin foraging is relatively rare, particularly in European derived bees. Instead, the colonies rely on physically removing the spores. Although self-medication by honey bees and ants has been discovered, it is possible that this phenomenon is more widespread in insects than previously.īees can sometimes distinguish harmful fungi from harmless ones, since colonies do not bring in increased amounts of propolis when infected with harmless fungal species. Its use as a mechanism of social immunity in bees and ants is complex, involving direct effects against parasites and more indirect effects on individual immunity. Resin collection and use by honey bees, as well as resin use across the animal kingdom is possibly a relatively widespread trait. The researchers found that, when faced with a fungal threat, bees bring in a great deal more propolis and they also physically remove parasitized larvae that the fungus was using to create fungal spores. This is a mixture of plant resins and wax that has antifungal and antibacterial properties. Wild honey bees normally line their hives with propolis. This behaviour must have evolved because the benefit to the colony exceeds the cost of expended energy. The colony is willing to expend the energy and effort of its worker bees to collect these resins. They bring in increased amounts of antifungal plant resins to ward off the pathogen. Researchers from North Carolina State University have discovered that honey bees ‘self-medicate’ when their colony is infected with a harmful fungus.
