Killing and replacing queen-laid eggs: low cost of worker policing in the honey bee [PDF]

, 2014
Worker honeybees, Apis mellifera, police each other’s reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%
