The last time I saw these ancient insects was about five minutes ago, when I was doing a general cleaning. A small herd of 30 heads of Blatella germanica was stationed under a cage with guinea pigs and was destroyed by suction with a vacuum cleaner and then placing it on a frosty balcony. I can assume that another population has been preserved behind a cage with chinchillas near the battery, well, let them live for now...

And if it's serious, then they live in smoking rooms... And nothing happens to them... And I consider the theory of radiation harmful to cockroaches to be absolutely devilish. I have both mobile phones and the Internet, and an apartment in the center, the pollution of the air is so to speak above the roof - and they do not sneeze or cough. In the microwave, they sniff carefully between the waves... Cthulhu is more likely here...

I give a hypothesis: rampant European repairs with a huge assortment of unverifiable building materials. I noticed that after the renovation, there are practically no cockroaches in the apartments, even if they were there before...

And do not swear at healthy humor... 31st day on the calendar!!!
A holiday is on the soul, and glory to G-d!!!

Freedom to cockroaches!

How great it used to be, you go into the kitchen at night, turn on the light - and prussians in all directions) And in the bathroom, you could sometimes admire the gallant black cockroach. For 10 years probably, if not more, as they disappeared in the apartment.
The reason here is most likely complex, first of all, of course, insecticides, I remember very well how my grandmother poisoned the tariks with dichlorvos-there was a whole ritual, meticulous spraying of corners and crevices.. and all to no avail))) And now.. poor tariqas )
Then, "European repairs", namely the sealing of all sorts of holes, cracks, leaky plumbing, in general, total glamorization deprived tariks of an ecological base-there was nowhere to live. Here is such a violation of environmental conditions led to the fact that the species Blattella germanica it is time to enter in the Red Book!!! And the apartments where the populations have been preserved should be declared nature reserves of national significance.

But cellular communication is really evil! Not for cockroaches, but for people. Here is the usual situation, you go to yourself on the steppe, to the nearest village 10 km, to the city in general all 30. And then the bell rings. You see that they call from work - you can't understand anything, because the connection is bad, and then for the rest of the time - an unpleasant aftertaste))) Although, of course, the primary evil is still work

Seriously, the only explanation that seems plausible to me is the transition to a new generation of insecticides (not "mashenek" and not "raids") of prolonged action. Prolonged action provides saturation of the population (s) with insecticide due to coprophagy, common in cockroaches. This also removes the objection: "and we did not poison anything like this, but the cockroaches still disappeared." Insecticides have a prolonged action and are designed to ensure maximum distribution in the population before action.

I am not a "programmer", and this information comes from specialists.

I am just a "programmer", but this explanation still seems weakly justified to me. What are " mashenki "and so on? These are all pyrethroids and organophosphates.
What I see on sale is no more up-to-date than this. Neonicotinoids (they accumulate), which are almost yesterday's day of plant protection, and penetrated the cockroach sphere. I'm still in favor of European repairs (lack of cracks + leaky plumbing + toxic materials = something that was discussed more than once on the forum, including above). Although, perhaps, the role of "mashenek" should not be underestimated.

FTOR, well, I see you recently registered, so this is just a culture shock for you ) Here are all serious discussions in topics about straightening, boxes and fringes on the wings)))
But the version about the radiation of cellular communication systems(CCC - uzhos

), and other radio radiation that negatively affects cockroaches is not very good. First of all, there was always radio radiation on Earth, and not weak and very different ranges, so that the first inventors of receivers heard on the air not crystal silence at all, but "white noise", and very strong.
In addition, if everything was so bad, and even tariks ran away and died from radio emissions, then there would be no insects in cities at all, because it is believed that cockroaches are the most resistant to any environmental problems, even they seem to live on NPP reactors. And if they couldn't withstand some mobile phones, then all the other beetles, spiders, and most importantly-mosquitoes from the basements

would have disappeared long ago. And here's figs for you!
In addition, here in my room the Prussians have disappeared and do not appear, but there is a huge colony of marbles, at least 1000, and nothing, they do not complain about radiation of any kind, they multiply in all!
But in the apartment-do not take root.

So the conclusion I think is simple - do not poison cockroaches, give them the opportunity to always have access to water, do not wipe the table and do not sweep the kitchen, feed them the remains of the meal, make them cozy cracks under the sink and spread newspapers wherever possible-and they will certainly please you(and neighbors too)) ) his running around the kitchen, not looking at any mobile phones and Wi-fi

PS
About the new year - that's for sure-a reason to drink

And most importantly-even the cold pulled up to the Netherlands!!! With such winters, it's not like cockroaches will disappear - soon only polar bears will live! Where is this Western Hyphen

I will not work with a "damaged phone". The conversation with a colleague was this summer. The reason is probably complex. On the other hand, it seems to me that you overestimate the number of "European repairs, lack of cracks, leaky plumbing", at least in St. Petersburg.

A year or two ago, there was a funny story - fellow geneticists asked to bring Blattella from St. Petersburg. The task turned out to be very difficult, I found it difficult to find a population from friends in the vivarium. A little while later, I complained about the lack of cockroaches to our manager. "Why didn't you tell me! In the next doorway lives a crazy grandmother from which cockroaches and twig, do not know what to do!" Like that. Since then, I have seen a few isolated cockroaches in my apartment.

According to my observations, the most stable populations of blattellas are found in vivariums, insectariums and other places that are united by one sign: you can not use insecticides there. Repairs in many places are quite modern (i.e. building materials are common, "harmful"), the level of radiation from mobile phones, etc. is also quite standard for a large city, products are quite common.

Naturally, these observations do not claim to be representative. We need research. By the way, it is quite possible to try to get funding for such work. Or maybe we're reinventing the wheel? I find it hard to believe that the vast literature on the control of synanthropic insects has not analyzed the influence of a wide variety of factors, including the ones we are discussing.

Let me give you some excerpts from the press that I managed to find so far:

Scientists of the Ilmen Reserve propose to include in the regional Red Book some species of cockroaches that until recently inhabited the entire Chelyabinsk region, but today have practically disappeared. Black, Lapland and steppe cockroaches became applicants for a lean attitude.

Last year, sanepidnadzor of the Altai Territory noted that over the past three years, only isolated cases were registered when residents turned to them for help in getting rid of "uninvited tenants". Entomologists, although they can not accurately determine why the cockroaches were attacked by pestilence, express a version: perhaps cockroaches do not have a relationship with genetically modified foods.

FTOR, no, this Duma is not a place for discussion

As for places where there are cockroach populations - in the Nikolaev Zoo, huge populations of several cockroach species are constantly registered-periplanets, blattellas germanica, and naufets cinerea, individuals from these populations, judging by the reports of residents of nearby houses, regularly visit nearby buildings during the warm period. In addition, another refugium of Blattella Germanica is located on the territory of a certain regional hospital No. X(coordinates are kept silent due to possible pilgrimages for such a rare species), and, apparently, the hospital located in this room is just a cover for the state nature reserve located there, since it is treated purely formally however, the damage is quite normal, which is obviously a consequence of the introduction of the principle of self-sufficiency of nature reserves, and all funds are obviously spent on maintaining the population of B. germanica, since extensive traces of work are visible on the territory of the building: cracks in the walls, leaking plumbing and raised floor coverings are plentiful, all this is obviously carefully maintained in the right condition and it creates a favorable environment for cockroaches to breed.

"Entomologists, although they can not accurately determine why the cockroaches were attacked by pestilence, express a version: perhaps cockroaches do not have a relationship with genetically modified foods."

It would be interesting to listen to a more reasoned version about GMOs, otherwise something is not very good, cellular communication is even more convincing.

Dear cosine,!!

Your answer is interesting for me because of its content. From it I understood that in Barnaul there are still Prussians in some dorms on the Stream, Sulima, VRZ and Ganba. But it is a pity that you did not describe so much under what conditions you met them. In general, this is strange - most of my contractors and subordinates from Barnaul constantly report that cockroaches in this city have disappeared almost completely. At the expense of cellular communication with you ready to disagree, and this is just because of the lack of arguments on your part. Frankly speaking, I myself do not try to warmly support hypothesis No. 1 because it does have some weak points, but there are not so few interesting facts related to it. For your reference: with the introduction of cell phones into human life, the incidence of glioma, meningioma, and astrocytoma (brain tumors) has clearly increased. Whether there is a connection or not - the answer is in the experiment. But the fact that the new connection and its biological effect is still poorly understood is a fact. There are very few published papers.

Dear Hierophis!!!
Thank you for such a comprehensive answer for your region. In the matter of cockroach extinction, the operational geographical information that you have generously provided and that can only be obtained through the forum is very important! Thank you.

GMOs are a separate and extremely interesting problem that stands apart!!! We immediately define the concept to avoid confusion in the future:
A genetically modified organism (GMO) is a living organism whose genotype has been artificially altered using genetic engineering methods. Genetic modification is characterized by a purposeful change in the genotype of an organism, in contrast to random, characteristic of natural and artificial mutagenesis. Currently, the main type of genetic modification is the use of transgenes to create transgenic organisms. A transgenic organism is a living organism whose genome has been artificially introduced with the gene of another organism.

I didn't quite understand one principle for myself. Well, look at this. A product with altered DNA enters the human (cockroach) gastrointestinal tract. Endogenous protease and nuclease enzymes immediately destroy the unique sequence of nucleotides in this DNA. And where is the place for a pathological effect here? But this principle works if the product enters through the gastrointestinal tract, and if it is inhaled, rubbed, etc. No less interesting are the principles of the transition of GM DNA into virion-like structures - this topic is generally closed (little knowledge).

The World Health Organization (WHO) has established a special program "Electromagnetic fields and human health". This problem is being given the closest attention around the world. American and Swedish scientists independently established a safe limit for human health for the intensity of electromagnetic fields-0.2 microtesla.
Here is data on the radiation levels of some household appliances that we all use all the time:

Refrigerator (equipped with the no frost system - at a distance of 1 m from the door) - 0,2 mkTl.
House electrical wiring-exceeds 0.2 mkTl.
Electric kettle - 0,6 mkTl.
Washing machine - 1 mkTl.
Electric stove - 1-3 mkTl ( at a distance of 20 -30 cm from the front panel).
Microwave oven - 8 MKT (at a distance of 30 cm).
Commuter train - 20 mkTl.
Tram, trolleybus - 30 mt.
At the metro station (when the train departs) - 50-100 MKT.
Vacuum cleaner - 100 mkTl.
In the subway car - 150-200 mkt.
Electric shaver - several hundred mcTl (when touched).

I cite these data not as an argument in favor of hypothesis No. 1, but as an example of the increase in the effect of these physical forces on the surrounding world with the arrival of a person on the planet.

But what about the fact that the natural background of electric magnetic radiation on Earth is very strong and in "rest" it is from 30 to 60 microns, and this is everywhere, and not just near electrical devices, as shown above. And most importantly, with the most ordinary magnetic storm, this background increases tenfold, and sometimes hundreds of times. And what is also interesting - the sunlight itself is also electromagnetic radiation

Really cockroaches, such ancient animals, could not adapt to all this

About GMOs - here I think you can refer to the same principle as with el. magnetic radiation - in the history of the Earth, living organisms are constantly changing, their DNA is also changing, and everyone has long been accustomed to this, so the fact that a cockroach eats a tomato with the jellyfish gene will not change anything.

But all sorts of toxic garbage of prolonged and not very effective action, which they stuff poor cockroaches with-they didn't meet much in nature before. Here is.

What is it

Only there was an interesting topic in which you can talk about how cockroaches plow the expanses of the CIS, and such shame

By the way, profanity is much worse than any EMP, they even say that the water spoils from this, so the cockroaches can not stand it. Not only is there enough of my own, but even after the collapse of the USSR, all sorts of obscene films went, I somehow accidentally came across a discussion of one film that was shown quite massively on TV, American eats.but, the translation of his "acute moments" was as usual, in the style of "damn it", "well, you're a fool" and so on, and what was there in the original.. here cockroaches can't stand it and leave, they understand everything)
