蜜蜂在蜂群过程中使用的许多信号中，有两种——停止信号和工蜂鸣叫信号——不容易区分，因为这两种信号都是由侦察蜂在振动翅膀肌肉的同时将身体压向其他蜜蜂时产生的机械声信号。为了弄清这两种信号在声学上的区别，我们记录了来自同一群和同一时间的两种信号，并在信号持续时间、基频和调频方面对它们进行了比较。停止信号和工人管道信号在所有三个变量上都不同：持续时间，174±64毫秒vs. 602±377毫秒；基频，407 vs 451 Hz；还有调频，缺席和存在。虽然目前还不清楚蜜蜂是利用哪些差异来区分这两种信号的，但很明显它们是这样做的，因为这两种信号有相反的效果。停止信号会抑制主动跳舞的侦察蜂，而管道信号会引起安静休息的非侦察蜂的兴奋。
Of the many signals used by honey bees during the process of swarming, two of them—the stop signal and the worker piping signal—are not easily distinguished for both are mechano-acoustic signals produced by scout bees who press their bodies against other bees while vibrating their wing muscles. To clarify the acoustic differences between these two signals, we recorded both signals from the same swarm and at the same time, and compared them in terms of signal duration, fundamental frequency, and frequency modulation. Stop signals and worker piping signals differ in all three variables: duration, 174 ± 64 vs. 602 ± 377 ms; fundamental frequency, 407 vs. 451 Hz; and frequency modulation, absent vs. present. While it remains unclear which differences the bees use to distinguish the two signals, it is clear that they do so for the signals have opposite effects. Stop signals cause inhibition of actively dancing scout bees whereas piping signals cause excitation of quietly resting non-scout bees.
