Can we use sound waves to disrupt bee swarms in regular airflows or in a normal Earths Atmosphere? Regarding breathable air. We know that in helium in a tank when exited by sound waves can cause enough excitement to cause water to boil and can be used for propulsion [steam engine] not a bad way to go if you have sound available.

So it does not necessarily have to be breathable to work. It could work in CO2 also. It could work in a cloud of gas, almost any gas. Probably the thicker the better and the more confined the better too [between buildings, canyon, cave, tube, pipe]; the more oxygen and heavier type gases the better actually unless confinement is smaller. So if you wanted to avoid lets say insects on another planet, you could use sound waves in whatever gas is there? But yes, we are talking about insects on the surface of the planet Earth and thus ambient air is important, but so is density and altitude. 29.92 barometric pressure to start.

If we are using sound waves to disrupt bee swarms or to steer them for flight deviation you could use an opposite approach. For instance find a frequency they like in the 230 beats range per second [honey bee wing flapping speed] and direct that sound and they may simply fly into that jet-stream of air so to speak where they feel more comfortable rather than not? As you enhance the conditions for them right? It appears from the discussions in the article you cited that the smaller the little unit (insect) is the faster the flapping speed or in this case the enhancement jet stream frequency speed needs to be to steer them. forward is eliminated and another equation is replaced.

What may be interesting to ask, so I will is perhaps the Reynolds Number for birds changes with size also for this reason. At least those birds, which are able to hover? Maybe that equation needs to be reworked or the size, width or area or all those dimensions of the wing creates another hyperbolic curve in size/flapping speed or where distance traveled. Knowing the exact speed may help in enhancement of flight and thus steering any flying insect based on wing shape, area, size or dimensions. From the article it appears a locust or a dragonfly would flap slower.

Now then if you want to prevent them from going somewhere, steer them, make a sound wall or stop them, then your frequency number probably should not be a multiple of that number, as you would assist in a rhythmic beat, that would be favorable not unfavorable? Is that right? So, for control use enhancement techniques where you want them and hostile frequencies where you dont with a progressively hostile band after that and then a small area of kill zone. Eventually after trained they will not pass into the level II and thus you do not need a level III (kill zone) anymore. Insects have memory, you can tell when you try to get a fly with a fly swatter, they figure that out pretty quick and then it is twice as tough to catch them the next time. Probably like cows, once you train them they are generally going to stay where they have been trained. Dog fences seem to work like this too, the collar shocks them a few times and they get it.

If you are trying to stop a swarm you need a good amount of energy and directed and it pays to have a choke point when you start the device up or you will find them going around the negative sound waves. But bees follow the queen bee and if she is in the center of the swarm or the front once you stop that you have generally stopped the swarm. Other types of insects would be different of course. Consider all this in 2006.
