Changes in the metabolic rate of the foraging honeybee: Effect of the carried weight or of the reward rate?

The metabolic rate of free flying honeybees (Apis mellifera ligustica) foraging on a multiple automatic feeder was measured in complete absence of perturbation. Each time the sucrose flow rate was doubled, the metabolic rate increased by 18.2 ± 2.0% (14.7 μl CO2 min-1) and final crop load by 25.1 ±...
