蜜蜂信号主要通过自然观察结合对殖民地或环境的操纵来研究，而不是直接操纵信号刺激或接收器。因此，我们对哪些信号方面是再现行为反应所必需的知之甚少。在这里，我们集中在震动信号，其中一个工人抓住另一个蜜蜂和振动。所有种姓都能接收到震动信号，但个体的反应取决于环境，信号可能是多模态的（机械、气味、声音等）。我们设计了一个工具来模拟震动信号。我们测试了一个纯粹的机械刺激是否会引起与自然震动信号相同的行为反应，并将信号和接收器特性的影响分开。我们发现，在人为摇晃后，工人和无人机都增加了它们的运动，并且摇晃的无人机比假对照更有可能进行喂食和梳理。这些行为变化支持了这样一种观点，即震动信号通常会增加工蜂的活动，但也会激活雄性生殖器（雄蜂）。有了这个工具，我们表明，振动本身是负责引起大部分的震动信号的行为反应，在社会昆虫中直接播放的少数例子之一。
Honey bee signals are primarily studied through natural observation combined with manipulations of the colony or environment, not direct manipulation of the signal stimulus or receivers. Consequently, we know little about which signal aspects are necessary to reproduce behavioral responses. Here, we focus on the shaking signal, wherein a worker grabs onto another bee and vibrates. All castes receive shaking signals, but individual responses depend on context, and the signal may be multi-modal (mechanical, odor, sound, etc.). We designed a tool to mimic the shaking signal. We tested whether a purely mechanical stimulus elicited the same behavioral response as a natural shaking signal, teasing apart the effects of signal and receiver characteristics. We found that both workers and drones increased their movement after being artificially shaken, and that shaken drones were more likely to engage in feeding and grooming than a sham control. These behavioral changes support the idea that the shaking signal serves to generally increase worker activity, but also serves to activate male reproductives (drones). With this tool, we show that vibration itself is responsible for eliciting much of the shaking signal's behavioral response, in one of the few examples of direct playback in social insects.
