The information is as follows:
The region is eastern Ukraine. Donetsk region.
Place - private farmsteads, vegetable gardens.
Symptoms - the bite is absolutely painless, at the site of the bite there is redness, the size of a nickel, with a clear single puncture in the center, from which in some cases, a drop of blood is released. After a while, soft tissue edema begins, with redness and pain when walking. Finally passes, after 1-3 days.
Local paramedics do not know what it can bite and what is needed for treatment, because they have never encountered anything like this.
I, based on my meager knowledge of entomology, can assume that this is some kind of bedbug.
So I have a question. What can it be? What can be the consequences and how can it be treated?
Thank you in advance.
Egor.

Good time of day.

I'm trying to develop a mosquito repeller, but I'm faced with the fact that I can't find what sounds mosquitoes reproduce, what they reproduce these sounds with, and what organs of sound perception they have. Like a bat's ultrasonic locator signal, it should serve as a signal of fatal danger to a flock of mosquitoes. However, nowhere, even in the specialized literature, could I find how mosquitoes perceive ultrasound, and whether they perceive it in general.

Dear experts, maybe one of you has relevant information on the structure of the mosquito's body, and the communication of mosquitoes with each other and with the outside world? As a last resort, can you recommend where to look for this information?.

Thank you in advance.

Dear professionals, the fact that there are very good chemical agents against mosquitoes is no secret to me. Mosquitoes, like all living things, must communicate. Therefore, they must have alarm signals, or danger signals. I know of a study that showed the inefficiency of radiation sources in a certain range of ultrasound. If necessary, I can provide a link. It can't be that none of the experts have published works on the study of sound signals of mosquitoes. If there are no such works, just say that such works do not exist in nature.

Sincerely, STALKER.

Well, in this case, read the topic: http://molbiol.ru/forums/index.php?showtopic=509313
From yourself:
In 1980, I collected a similar repeller according to the scheme from the magazine "Young Technician" (there was such a one in the USSR): the result is no other than the effect on my own ears

, and since then I have been using only chemistry.

Why are you so sure that a) they should communicate and b) they should communicate using sounds (not chemicals, for example)?

Dear, I assume that they should communicate. I don't know what they communicate by, sound or chemistry. I'm not a professional in entomology. For this reason, I asked the professionals that I wanted to hear a normal specialist's answer. However, I still don't see a serious response from a professional. And preferably with a reference to the literature. Those answers that I read are the answers of people like me who are just interested in entomology. The person gave a link with the words "in this case, read this", but this is just a discussion, but not a link to at least a professional article.

Sincerely, STALKER.

if the word communication is replaced with the word communication, then everything is simpler:
"How is acoustic communication of mosquitoes carried out? The male's hearing organ, the so-called Johnston's organ (Figure 10), is located at the base of the antennae, which, unlike the antennae of females, are densely covered with hundreds of long hairs. These sensory hairs act as resonators of the female's "voice", separating the main tone of the female's flight from her own tone and other sounds. The two antennas located on the front of the head are located at a certain angle to each other and serve as an ideal device for stereo sound perception. They not only perceive sound waves coming from the female and transmit them to the brain and other centers, but being independent in their movements, they act as locators that determine the approximate location of the female." http://komar.molbiol.ru/komar_28.html
