Scientists using highly sensitive vibration detectors have decoded honeybee queens' "tooting and quacking" duets in the hive.

That honeybee queens 'toot' has been known for a long time but I've not heard of it in this context, here's a sample:

Beekeepers are generally keen to prevent or at least control swarming and BBC sound engineer Eddie Woods discovered in the late 1950's that variations in the 'warbling' sound made by honeybees could be used to predict imminent swarming. He invented a device called the 'Apidictor', I used to have a copy of the wiring diagram but gave it to someone doing research about it:

Eddie built a simple audio frequency amplifier with microphone and headphones and incorporated what is known as a bandpass filter. This allowed the frequency band 225-285Hz through to the ear and blocked off the rest, making it easier to hear.
