蜜蜂对人工花蜜来源的觅食访问时间的能力与食物来源呈现的时间有关。在每个特定的实验中，每天只在特定的1小时内对食物来源进行定向和训练的一致方案，允许在不同喂食时间训练的蜜蜂组之间进行定量比较。在早晨训练的蜜蜂表现出最精确的计时能力；那些被训练到中午或下午晚些时候的食物来源的人明显不太准确。在所有的实验中，蜜蜂都预期了训练期的开始，但反应中预期成分的持续时间取决于训练时间。同样，描述觅食飞行在时间上分布的其他参数（偏度系数和峰度系数以及训练时间结束后立即到达次数的关闭）在提供食物源的昼夜周期中也会随着时间的变化而变化。蜜蜂可能更有效地利用每日花蜜来源，如果它是在清晨提供比如果它是在晚些时候。讨论了观察到的时间取向差异的可能机制。
The ability of honeybees to time foraging visits to an artificial nectar source was analyzed with respect to the time of day of food source presentation. A consistent regimen of orientation and training to the food source, which was available only during a specific 1 h period of the day for each particular experiment, allowed quantitative comparisons to be made among groups of bees trained at different feeding times. Bees trained early in the day showed the most precise time-keeping ability; those trained to midday or late afternoon food sources were significantly less accurate. In all of the experiments, the bees anticipated the onset of the training period, but the duration of the anticipatory component of the response was dependent upon the training time. Similarly, other parameters (coefficients of skewness and kurtosis and the shut-down in the number of arrivals immediately after the end of the training time) describing the distribution of foraging flights in time varied according to times in the diurnal cycle when the food source was offered. Honeybee may more efficiently exploit a daily floral nectar source if it is available early in the morning than if it is offered late in the day. Possible mechanisms underlying the observed differences in temporal orientation are discussed.
