The model may be a bit simplistic, but work by Maurizio decades ago,
confirmed by Crailsheim and students suggests the following
dichotomous conditions of workers:
Winter bees: Developed hypopharyngeal glands through their lifespan,
no feeding or minimal feeding of brood, extended lifespan.
Summer bees: Hypopharyngeal glands develop initially, feeding of brood
reduces their size, reduced lifespan.
I believe Maurizio showed that in the summer, the equivalent, or close
to it of winter bees could be produced by simply preventing young
workers from feeding brood.
The nutrition that larvae receive may be a slight nuance in
determining physiological state of individual workers. Very
simplistically again, actual feeding and rearing of brood is somehow
modulated to resources available to the colony so as not to produce
"sub par" workers.
