title: [Studies on the rectal pads of the honey bee Apis mellifca].
abstract: According to earlier investigations young bees show a rectal fluid hypo-osmotic to the haemolymph. It had been assumed, however, that in certain situations honey bees have to be economical with water and simultaneously form a rectal fluid hyperosmotic to the haemolymph. The latter has been confirmed by the present investigation.
