Hi all
One of the perennial topics in beekeeping is Queen supersedure. If you are new to beekeeping you might get the impression that this is a recent problem, but it isn't. This is from 1937:

> During the past year the Department has employed a trained geneticist for the first time in its beekeeping work. His immediate genetical problem is to determine whether heritable factors affect supersedure, especially the premature supersedure of queens sold commercially. By "supersedure" is meant the replacement of the queen by another reared by the colony apparently for that purpose. If heritable factors play a part in this behavior, they may be in the behavior of the queen alone—lack of fecundity, for example—or they may lie in the behavior of the workers—for example, undue hostility to a queen reared in another colony.
