On the edge of the supernatural, what is most surprising is the word of the Director of CENASA (National Center for Diagnostic Services in Animal Health) who takes us by surprise by assuring "it is about some men who are making those cuts to the cows. knows for what reasons ". Maybe "some men" should ask him to resign.
I apologize if for a moment I get off my subject and join, confused, the surreal notes of Argentine television.
Everything seems to indicate that unidentified flying objects have been walking through different parts of our country collecting samples of some animals. There are really amazing unknowns, why are there no footprints of people or vehicles? Why only some parts of the animal? Why don't animals rot?
The media have tried to explain these episodes based on the reports to different characters including: farm keepers, veterinarians, so-called connoisseurs and, obviously, people who describe blue lights and lumps that wiggle. Nobody seems to know for sure what it is. But when in doubt, the notes are decorated with the music of The "X" Files and there is talk of "strange cuts".
The reality is much more earthly:
The attacks are due to the Germanic Vespula, better known as "Yellow Jacket" or German Wasp. This strange wasp attacks the fruits and feeds by stealing honey from honeycombs. But when the first intense cold arrives and in the absence of honey, it becomes a carnivore.
It attacks dead or sick animals (this wasp not only stings, it also bites) but since it cannot penetrate the thick leather of cows, it attacks in a massive way the udders, the anus, the tongue, the eyes. Many locals wondered why only one eye? The answer is simple, the cow fell supporting the other on the ground. The thousands of micro-bites make the cut meat look seared.
In many cases, when choosing dead animals as victims (which in many cases die since being sick they do not resist low temperatures) it is normal that they do not bleed. Wasps do not leave footprints in the ground or grass. And the animals do not decompose quickly since a wave of intense cold just arrived.
When the wasps attack, they release Ferhormones, that indicates to other animals that they are going to attack and not even the raptors come close. The attacks stop abruptly, with the next frosts all the wasps die leaving the queen buried incubating the eggs of future generations.
What is really strange is that these little insects are not at all unknown in our country. The I.N.T.A. He has been studying them since the 1980s, when they arrived from Chile, where in turn they had arrived from Germany. Even Doctors Juan Corley, Paola D´Adamo, Mariana Lozada and Paula Sackmann managed to produce a bait that INTA sells in experimental doses at $ 3.- and gives very good results.
THE OFFICIAL WORD
On the edge of the supernatural, what is most surprising is the word of the Director of CENASA (National Center for Diagnostic Services in Animal Health) who takes us by surprise by assuring "it is about some men who are making those cuts to the cows. knows for what reasons "
Without a doubt they are men in a car because in two days they traveled between La Pampa and Entre Ríos and then to Uruguay. Perhaps the director of CENASA's telephone broke and he was unable to communicate with INTA before speaking to the media. Or perhaps he wanted to make one thing clear: The directors of national entities are political positions and they do not have and should not know anything about it, even when it comes to informing the population that pays their salaries through the media.
Maybe "some men" should ask him to resign.
THE BLAME OF EVERYTHING IS OF BATISTUTA
Perhaps the media are selling the "UFO phenomenon" that is already known to be very lucrative or perhaps they are trying to keep the public busy. The truth is that if Batistuta had scored a couple more goals we would never have found out (as happened in previous years) about the existence of the dead cows.
The media can trigger an anti-information mechanism caused by the lack of news. The same thing happened last year with the shark attacks in Florida, they showed us that the sharks had gone crazy, were invading the shores and seemed to want to eat everything. This sounded strange especially for those who knew that they were within the statistical framework of all the years and before the same groupings of sharks as always.
Coincidentally, no shark attacked again after 9/11.
I enclose, below, a work from INTA that Dr. Omar Sánchez, our school doctor, sent me on how to stop the advance of the German wasp, something that the Director of CENASA should be internalizing.
This email was not written by a person who disbelieves in UFOs, but by a person tired of so much television stupidity, of so many poorly sold stories. On the contrary, every time I visit Patagonia at night, I usually look up to the sky, looking for a clue. A light that indicates that there is someone else there, someone with enough intelligence to get to us before we get to them, I don't see how they got here to steal the udders of a cow.
A superior intelligence, a light that illuminates us and perhaps even gives us some knowledge in the midst of so much unusual, stupid and embarrassing mediocrity.

SAN CARLOS DE BARILOCHE (AB) .- Through the placement of toxic baits and the occasional destruction of their nests, experts from the local INTA station have managed to reduce the abundance of yellow jacket wasps, which are especially bothersome during the summer season.
The concern that caused the proliferation of "yellow jackets" in urban environments in recent years led INTA scientists to begin to develop a pest control project.
Finally, the team made up of Juan Corley, Paola D "Adamo, Mariana Lozada and Paula Sackmann, managed to produce a bait that INTA sells in experimental doses at 3 pesos, and produces very good results.
The local population and tourists express their amazement and concern at being harassed while they carry out outdoor activities, and especially denounce the predilection of wasps for roasting, which earned it the nickname "carnivorous bees".
Medical consultations related to wasp sting have also increased in recent times, and although the researchers recognize that they will have to be lived with, they are already in a position to limit the development of their colonies through scientific control methods.
These voracious insects, which feed on fruits, flower nectar and animal proteins, entered the country in 1980 accidentally and today their colonies extend from San Juan and southern Buenos Aires to Santa Cruz, between the mountain range and the coast.
The presence of these wasps has been causing a strong impact on fine fruit plantations, bee colonies and beekeeping for years, despite the fact that it is poorly developed in the area.
Scientists deny the theory that these wasps were imported to fight horseflies and earwigs and accept that they can bite people and animals - especially in exposed wounds - to provide themselves with proteins with which they feed their larvae, since the workers cannot digest them.
It is assumed that the species is native to Europe -its scientific name is vespula germanica-, from there it reached the United States and on a cargo ship from San Francisco to Valparaíso.
The first sighting in Argentina occurred in 1980 in Andacollo, located about 60 kilometers west of Chos Malal and 30 from the border with Chile, and the speed with which it spread throughout the region was surprising. A year later they had settled from Aluminé to Epuyén, invading three provinces.
The greatest impact is caused in beekeeping, because in autumn the activity of bees decreases, while the wasps accelerate theirs. At that time they feed their queens before hibernation and attack the hives to kill the bees and eat the honey. The wasp does not accumulate food. The worker feeds and provides her queens and drones, which sometimes regurgitate part of the proteins that they can digest.
Bees and earwigs are part of the diet of queens and drones, and the fine fruit also suffers the predation of yellow jackets, and the collectors their bites, always in response to a stimulus or contact.
"When the density of jackets is very high, they leave the cherry pit hanging from the tree," exemplified an expert, and also commented on the serious consequences that a massive attack on a human being can have.
The researchers aim to get to know the insect in depth and establish control at the regional level, without thinking for now about eradicating it.
How to "treat" nests
Underground nests are easier to remove, flooding them with diesel or other fuel and covering the entrance, but overhead nests or those built inside a house require greater precautions. When injecting an insecticide they can look for other exits and enter the house, that is why the INTA bait is more recommended, using it correctly.
In autumn, when natural food is scarce, the wasps become more annoying. Unlike bees, these biting and stinging wasps survive stings because they have smooth stingers. To the tranquility of the neighbors, the researchers assure that the colonies die in winter and only the queens survive. At the beginning of the following spring they will start to form new colonies and at that time they must try to locate the nests and destroy them with fuel or poison.
Characteristics of the pest
The appearance of the jacket is similar to that of the bee and although its body is yellow and black, they are usually confused. Nests or colonies of up to 4,000 individuals are built by a founding queen, fertilized in the fall, who survives the winter under the bark of a tree or other protected site. These nests, underground or aerial, are built in a cellulose paste that the wasps make with vegetable fibers. They make them in holes or burrows already built, or in walls or attics.
Yellow jackets are fed carbohydrates, protein, and water. The former are obtained from honeydew and ripe decomposing fruits, and the proteins are incorporated by preying on invertebrates or remains, and aggressively attacking bee hives and domestic cattle that present wounds. Their ghoulish habits make them cohabit with humans in urban areas, feeding on waste or unprotected food, and they can even bite people.
Experts point to beekeeping as the activity most affected by yellow jackets and second to fruit growing, but in Bariloche they affect tourism in a special way, because they constitute a nuisance for outdoor activities and can cause serious bites, with serious consequences in allergic people. In outdoor roasts it is advisable to pay attention to what is put in the mouth, because they tend to rest on food and do not scare easily. Livestock are affected by the plague, since jackets attack wounded animals, at the time of calving or during milking.
