Female insects that survive a pathogen attack are known to produce pathogen-resistant offspring. This process has been coined as trans-generational immune priming. We have shown that in the honey bee (Apis mellifera), the egg-yolk precursor protein Vitellogenin transports fragments of pathogen cells into the eggs. Honey bees live in complex societies where reproduction and communal tasks are divided between a queen and her sterile female workers. We study how the signal about pathogen presence in the environment is transferred in the beehive and how this information is used by the queen to make the hive more resistant against the diseases.
