There is some evidence for reduction of working behavior in reproductive workers, thus there could be a reduction in colony fitness if there were too many anarchist bees. 
 + 
 +5. Sterility in workers is (mostly) regulated by a single //locus//, called //Anarchy//. 
 + 
 +6. In other groups of Hymenoptera, such as pomerine ants, workers can also reproduce sexually, so that a numbers of species have a different type of social organization without the need of the queen caste.

-Investigate the dynamics of worker reproduction in //Apis mellifera// colonies.+Investigate with mathematical models how the dynamics of worker reproduction in Hymenoptera affects the stability of colonies.  
 ===== Proposed Questions ===== ===== Proposed Questions =====
  
 +  * Is it possible that worker reproduction may occur at a stable rate without destabilizing the colony as a whole?
 +  * How does sexual reproduction between workers changes such stability?
