Re: Larvae age
From the time the egg hatches until the resulting larvae is 2.5 days old, the bees can make a queen. The older the larvae, the less queen characters will be produced. In particular, the number of ovarioles that produce eggs will be reduced. From 2.5 days old to 4 days old, bees can produce intercaste queens that show part worker part queen characteristics. The best queens are consistently produced from eggs up to 12 hour old larvae. Steve Taber wrote quite a bit on this subject, also, quite a bit of research was done in the 1940 to 1970 time frame.
