Fig. 5. The fit of a mathematical model of suction feeding
(Daniel et al., 1989) to
measurements from Euglossa imperialis. These data points were
measured from starved bees, but were multiplied by a correction factor of 1.39
to be applicable to freely foraging bees. (A) Pressure drop versus
sucrose concentration assuming a fixed radius of 0.045 mm; (B) mechanical
power output versus sucrose concentration; (C) sucrose intake rate
versus sucrose concentration.
