Scientists have found that a jolt of caffeine helps bees stay on task and get the job done more efficiently. Arnold and her colleagues showed that feeding bumblebees caffeine while exposing them to a target floral scent encourages them to seek out that smell when they leave the nest. The caffeinated bees visit the target-scented flowers more quickly and often than those without that extra boost.

科学家们发现，咖啡因的刺激有助于蜜蜂专注于任务并更有效地完成工作。阿诺德和她的同事表示在给大黄蜂喂食咖啡因的同时让它们接触目标花香，会激励它们在离开巢穴时寻找这种气味。带有咖啡因的蜜蜂比那些没有额外刺激的蜜蜂会更快、更频繁地造访目标气味的花朵。
