title: [Radioisotopic demonstration of seasonal variations in food transfer between worker bees].
abstract: Food exchanges have been studied during the whole year between workers of unknown age and 4-days old workers. Variations exist between both groups. The mean percentage of shared food is 27% in the group of honeybees of unknown age and 40% in the group of 4-days old workers with respect to the initial intake of the giver. The effect of the season appears among workers of unknown age particularly.
