Mosquito and ultrasound

As far as I know, work on determining the effectiveness of ultrasonic repellers has been carried out both here and abroad. Their effectiveness is zero. This, however, does not prevent them from selling successfully.

And what does science say about this? Is a mosquito even able to hear?

Somehow that's what science says:

Yes. With your mustache. For example, a male is attracted to a female by a sound in the 400 Hz range.

But in the practice of using repellents, I have not heard that they work. I bought my first and last one back in 1989 (then I fell for such an electronic toy). It emitted in two switchable regions, in the ultrasonic range, and in the audible frequency of the sound of dragonfly flight. To scare away mosquitoes with the sound of their natural enemy.
But this thing in real life for some reason did not scare off mosquitoes and I quickly stopped using it. The mosquitoes probably didn't understand that they were supposed to be scared.

Let me explain my previous post. I didn't work with mosquitoes, I worked with ticks (Ixodes persulcatus). From parasitologists, and from people who have worked directly on this topic, I have repeatedly heard about ultrasonic mosquito repellers as an example of fraud. Since the question arises periodically, I will try to find and post publications.

I think that maybe mosquitoes will get scared if the ultrasound power is not small.
For those who have "retona"- a good reason to do an experiment, because retona is a powerful emitter of a fairly good, suitable ultrasound.
I have one, but I need to change the transistors there, and I'm too lazy yet, and I don't have time.
PS
The truth erases retona not very much, if it also repels mosquitoes will not go

No such thing gentlemen! Here the campaign needs a more serious one. For half a year, we improved the dog repeller by trial and error. And only by achieving a frequency of exactly 24.3 Khz (at 120 Db) did we get an excellent result.Although the Chinese make a range of 20-25 kHz (consumer goods). Okay, figs with him with a repeller. I mean, the idea is that ultrasound should repel mosquitoes. On the websites of merchants, it is written that --Is designed to repel mosquitoes and mosquitoes from a person indoors and out. The principle of operation is to simulate the sound of a male mosquito's flight. Biting females avoid the sounds generated by male mosquitoes generated by the repeller. That's why I'm asking for your help as an entomologist. It turns out that you can achieve a certain frequency of the male's sound so that the females do not fly. Or it's all nonsense.

Since I've dealt with two dog repellents, the most powerful one I found and bought in 2003 (in the US) has stopped many (but not all!)of them. at a distance of about 7 meters, then I wonder what is the power of yours, at what distance does it keep the dog from approaching further? Have you tried it on many breeds?

Thank you so much for the link. But that's all in English,not a damn thing is clear. My mother told me-learn English(c) .

Unfortunately, ongoing tests show that they, these ultra-sonic mosquito repellents do not repel mosquitoes. You can do a search, and here nothing came out of testing such devices that in 1977 that in 2007

Why avoid it? I mean, is it a guess or a fact?

Thank you very much! So the topic can be closed? It's a pity, damn it. Or maybe there is another way out?
