[Dose/response relations of insulin and glucagon on honeybee glycemia].

Two hours after insulin-injection to emerging bees, hypoglucosemia occurs significantly with doses from 10(-2) to 10(2) ng per bee, with a maximum (-53 p. cent) from 0.1 to 1 ng, that is equivalent to 0.02 to 0.2 i.u./kg. Hyperglucosemic effects of glucagon, 1 hour 30 mn after injection, are significant with doses from 10 to 500 ng per bee, with a maximum (+ 146 p. cent) for 100 ng, that is: 844 micrograms/kg. The trehalosemia shows lower variations in the same time.
