While the whole world is eliminating pests, America is breeding "people-eating flies" that can turn livestock into bones. However, this is not a weird experiment, but a human counterattack against the raging human-eating flies. It is clearly providing food to pests, why is it a counterattack against human-eating flies?
The man-eating fly feeds on blood
In 2013, British tourist Harris returned from traveling in Peru, South America, but encountered an unimaginable nightmare. On the return flight, Harris felt a burst of noise in his ears. At first, she thought it was the discomfort caused by the plane and didn't care much. Until he returned home, Harris' ears began to flow into pus, and even emitted a foul smell.
Harris hurried to the hospital for examination, but scared the doctor and the traveler at the same time. The doctor actually found dozens of maggots that were still wriggling in her ear canal. After further examination, Harris' ear canal was bitten into with a blood hole of about 51 cm. If she did not remove the maggots that day, then the bugs would crawl directly into her head, and the consequences would be unimaginable. What caused this horror phenomenon was actually a fly called New World Spiral Fly . They laid their eggs in Harris' ears, and a few days later, the eggs hatched maggots and began a "parasitic life".
Don’t underestimate this kind of flies, they have another dangerous name "Man-Eater Flies". Most people are unfamiliar with the name cannibal fly, because spiral fly generally only appears in the Americas.
They are slightly larger than ordinary flies. Like green-headed flies, they like to lay eggs on the flesh. But the difference is that compared with rotten meat, man-eating flies prefer to lay their eggs on living constant temperature animals, so that their larvae can feed on the fresh flesh of the animals.
The cannibal flies that need to lay eggs will lay eggs in the wounds of the target animal, or in the holes such as the nose, ears, eyes, etc. It only takes a few days before these eggs hatch into larvae. This is just the first step for human-eating flies to eat their bodies. When the larvae hatch and take shape, it is the beginning of the nightmare.
What really causes animals to die is not adults, but these human-eating flies. There are two pointed teeth on the mouth of the man-eating fly larvae, which can help them eat the flesh and blood; here it should be noted that spiral flies are not because they really have spiral patterns, but because the larvae have a circle of spiral-shaped thorns, so they have this name. At the same time, these thorns can also help them wriggle into the animal's body and eat the animal's internal organs.
A man-eating fly can lay about 100 eggs at a time. Once these young maggots are born, they will begin to feed the animal's body and blood randomly. In just 2 days, these larvae can eat all the external organs such as the skin, eyes and other large bull. When they grow into young flies the size of grape grains, they will begin to invade the animals and eat their internal organs until the parasite dies.
After humans discover human-eating fly eggs and larvae, they can be cured by debridement and disinfection of wounds. But in the wild, the animals have no way to remove human-eating flies by themselves, and can only let them chew on their bodies.
The man-eating flies are becoming more and more rampant in the Americas
In 2016, a large number of " zombie deer " appeared in the United States. They were filled with caves of all sizes, and some of them were even eaten, and most of their heads were even shaking their heads and wandering around the forest. In just a few months, 83 deer died in this situation.
These deer are all hosts who were unfortunately targeted by man-eating flies. When people discovered them, they were already seriously injured and had severe ulcers. There was no way to save them. They could only watch these animals be gnawed by man-eating flies until they died.
Overall flies can only eat scorch, but human-eating flies feed on the fresh flesh and blood of constant temperature animals.Once a man-eating fly appears, it will cause great harm to both humans and animals. At first, spiral flies were only rampant in southern America, but because they had never found a way to eliminate human-eating flies, they became more wanton and gradually focused on American livestock.
In 1935, in Texas, the United States, 180,000 livestock were swallowed by spiral fly larvae. In the 1950s, man-eating flies caused the American animal husbandry and dairy industry to lose more than $200 million each year. Is it so difficult for man-eating flies to be eliminated?
In fact, American scientists have also tried to use various methods to eliminate man-eating flies, but these fly are all active in the open wilderness. Generally, electric fly swatters and purple lights cannot be used, and insecticides do not harm them much. Ranchers can only check the skin of livestock to see if man-eating flies lay eggs on them and remove them in time.
However, the eggs of human-eating flies are difficult to be discovered under the cover of animal hair. Even if they are found, it is difficult to be completely removed. The method of finding and eliminating through human power is not only time-consuming, but also not obvious. Since we cannot eliminate human-eating flies from the general environment, we can only start with human-eating flies.
Human counterattack started with "dead of children and grandchildren"
1946, Edward, an insectist at the American Agricultural Research Institute, was inspired in "Drosophila", which mentioned that " nuclear radiation can cause fruit fly infertility." So he had a bold idea: Since female cannibal flies only lay eggs once in their lifetime, if they cannot reproduce the next generation, over time, will the spiral flies become extinct?
does it right away, so Edward immediately formulated his "radiation sterilization method" .
People first capture some cannibal flies and send them to the breeding ground, allowing them to reproduce naturally for the next generation; then the hatched larvae are collected in a tray with odor and touch that is very similar to the animal's fur. During this period, the breeder will feed the larvae with fresh meat and plasma.
Two days later, these larvae will be sent to receive nuclear radiation. The radiation dose of these nuclear radiation is 10 times that of the human body, but it will not kill the human-eating fly larvae, and will only cause them to lose their fertility when they become adults. Subsequently, these breeding objects who have undergone "sterilization surgery" will be sent directly to the severely affected areas where human-eating flies are present and "released", allowing them to mingle with normal human-eating flies and reproduce naturally.
Because these cannibal flies have long lost their ability to reproduce, the cannibal flies after mating will not lay eggs and reproduce, and will not cause harm to wild animals and livestock.
After a period of observation, the researchers found that the density of man-eating flies has indeed been greatly reduced, and this "radiation sterilization" experiment was very successful. After that, this method was quickly promoted to many countries that were persecuted by man-cannibal flies.
In 1982, the man-eating flies in the United States almost disappeared. Ten years later, Mexico also announced the extinction of man-eating flies. By the late 1980s, scientists also used radiation sterilization to effectively control more than 70 insects such as Qiujiafly and red bellworm , and directly eliminate harmful insects from the source.
However, in recent years, there have been still some areas where people cannibalism have broken out, so people still cannot take it lightly. When you are away, you should also take good protection. If you are accidentally bitten by mosquitoes or suddenly feel uncomfortable, you must deal with it in time.
