Reward rate and forager activation in honeybees: Recruiting mechanisms and temporal distribution of arrivals
We analyzed the foraging and recruitment activity of single foragers (Apis mellifera), exploiting low reward rates of sucrose solution. Single employed foragers (test bees) were allowed to collect 2.0 M sucrose solution delivered by a rate-feeder located at 160 m from the hive for 2 h. Flow rates va...
