title: [Mechanisms in the group effect of honeybees].
abstract: We consider the group effect on the mortality rate of honeybees and on the development of certain of their organs the mortality rate isolate honeybee varies according to the time of year, which leads us to believe that the group effect has an alimentary origin, at least at the outset. A sensory and perhaps pheromonal origin is equally demonstrated. Moreover, there is a group effect on most of the organs studied.
