Thank you for sharing.
A couple of suggestions on this "phenomena" has suggested CO2 or heating fr=
om your mouth to your mic, but shouldn't the mosquitoes/mic have been react=
ing when you whistle then?
At least to me it sounds like they react to your voice frequency.
I can be something else of course...
I might try to do the same experiment if I find the time.
