The role of flies (the larvae of flies) - the most efficient recycling station on Earth.

Many people in life may have had this experience: eat dragon's eye, lychee and even grapefruit to eat half, but was surprised to find that there are white fat fresh bugs in the creep.
at this point, you may immediately throw them away and rush to the side to make a vomiting gesture.
's little mates will also take advantage of this to fall, joking that you add a lot of protein.
not unexpected, all we meet in this case are flyflies.
as the larvae of flies, they often lack attention because of the nausea of the population.
in fact, they are the most efficient machines in nature that evolve to eat rot and are the most efficient recycling bins on Earth.
they are not only secret weapons for forensic detection, but are also used to make dishes, develop feed, aerospace food and so on.
, it may be able to deal with antibiotic residue contamination and its drug-resistant genes, and even clean up large wounds that are difficult to heal on the human body.
and their strange structure and interesting habits are also used to paint, a change of our stereotypes.
although we are very common in our lives to fly, but I'm afraid not many people can say exactly what they look like.
to put aside the fear and antipathy of their instincts, flies are also a perfect masterpiece of biological evolution.
they have a pair of very sharp, curved hooks on their heads that can effectively tear off food.
no matter what food they encounter, the pair can help them dig a passage.
but their smooth body surface, but there are several circles of ring-shaped tissue full of protrusions are very bright.
it is these ribbon-raised rolling edges that allow the aphids to move freely in a changeable environment.
otherwise they're going to be hard to get free to shut freely through the leftovers we've been putting in for a long time.
the tick's breathing hole does not grow on the head at all, but is cleverly hidden into the tail of the body.
so that they can continue to eat when their heads are buried in rotting food.
because as long as the tail is still in the air, you can breathe very smoothly.
interesting place is here, flies generally only eat and do not excrete.
even some of the flies that have this need emit very small excreta.
about turning around and being wiped out by his own companions.
and ecologically, flies and their larvae are bipedles that act as decomposers in the Earth's ecosystem.
in fact, the meaning of "fly" refers to eating less and breeding more insects.
and flies are popularly known as flies' children.
high school textbooks we have learned that flies are completely perverted insects.
its life history includes four stages: eggs, larvae (flies), ticks, and adult insects (flies).
of course, different flies do not complete these four stages in equal time.
but on the whole, they reproduce very quickly.
and a female fly lays an average of 100 to 200 eggs per time, each pair of domestic flies can reproduce 10 to 20 generations in a year, according to biological estimates, the family fly has the ability to produce 100 million offspring in a lifetime, the number is really staggering.
, the eggs emitted by adult female flies are very small.
predicted, the number of eggs per gram would reach about 13,000.
currently known about 3,000 species of flies in the world, and about 500 species in China.
most flies of aphids are harmless, but a small number of flies will live in the human body, causing fly tick disease, etc. , but its incidence is very low.
different flies have different tastes in food.
for example, some like to eat melon fruit, plant juice, fermentation products, etc. , some are greedy for rotting meat, human and animal feces and other rotten substances; After
, they can become moths and then feather into insects (flies). One of the great weaknesses of the
flies is their fear of light.
when the bright light shines, it will try desperately to drill into the bottom of the food.
and temperature has a great influence on the growth and development of flies.
the higher the temperature, the more nutrients it consumes, and the faster the growth and development of flies.
the larger the fly, the larger the turn into a fly, the more fat the fly is.
because of its light-avoiding nature, most of the flies are found mainly in human and animal waste piles, garbage, rotting animal carcasses.
early in history began using these flyflies for forensic identification, and in general, flies gathered within seconds of the victim's death.
by judging when the aphids grow, we can accurately infer when the murder occurred and the deceased died.
, they were once a good helper in forensic detection and solving cases.
, most of us have regarded flying flies as filth and avoided them since ancient times.
it wasn'
that Chinese scientists discovered that flyflies degrade environmental waste and are used to dispose of animal-cultured faeces.
in fact, at a time when there is a global shortage of protein feed, scientists began to study flyflies with the focus of extracting their proteins.
the United Nations Food and Agriculture Organization (FAO) has long initiated initiatives to develop and apply "micro-livestock farms" dominated by edible insects to provide protein for livestock and poultry.
even scientists extract its high-quality protein for the development of aerospace food, medicine and so on.
With the further research, they found that by breaking, flipping, ventilation and other physical processes of feces, so that it is fully "exposed" in the fly and microbial environment, the feces can be degraded biotransformation.
in this, the role of flies is mainly enzyme degradation.
they secrete protein hydrolysis to digest the proteins.
such as protease, sterase, amylase, cellulase, etc. secreted by the digestive system of the animal's internal organs.
, it can also quickly degrade organic macromolecules such as protein, fat and carbohydrate in waste into small, easily soluble and absorbable organic matter.
next, about two-thirds of small molecules of organic matter are further degraded into carbon dioxide, water and inorganic substances through the metabolism of flies. about one-third of the
of the other organisms are converted into the flyworm itself through growth and development.
, they can break down and absorb the remaining nutrients from animal carcasses and turn them into new life.
current research has found that flies degrade pig droppings by 40 to 80 per cent.
2016, an associate professor, Zhang Zhijian, of Zhejiang University's School of Environment and Resources, led a team that found that flies can degrade antibiotics and drug-resistant genes in animal feces.
no doubt that this new feature will provide new ideas to solve the problem of antibiotic residue pollution and the spread of drug-resistant genes in China's breeding industry.
not only in forensics, agriculture, flies in medicine also play a significant role.
history, there is a sensational aphid therapy.
it began in the 9th century and was introduced to China in 1998.
as the name suggests, aphid therapy is the use of medically sterile aphids to help clean up festering wounds and eat necrotic tissue and bacteria that prevent the wound from recovering.
doctor will determine how much damage is needed based on the size of the wound, implanting the mole on the surface of the wound and putting it on medical tape.
these medical aphids only gnawed the rotting meat cleanly on the wound without damaging healthy muscles.
and the mole will not be excreted in the wound, but it must be removed before it is turned into a mole.
December 2011, French scientists said that aphids were even faster than surgery to clean large wounds that were difficult to heal.
although this conclusion has not been fully confirmed, but aphid therapy in the treatment of diabetic feet, foot festering, skin festering and so on have certain advantages.
the current medical practitioners are still in further clinical research, the use of the treatment of patients must also be under the guidance of a doctor, can not casually.
see here, we know that flies have a variety of uses, will not lose the antipathy to it? It is still difficult for most people to overcome their natural fear of it at once.
to improve the situation, Irene Watson, an entomologist at the University of Southeast Louisiana, created a series of watercolor paintings using aphids.
she put the flies in a drop of watercolor paint, so that they climb up and down on their own.
so, the flywill will drag a colored curve on the paper, cross-integration, and gradually form a "picture."
some people liken these soul paintings to "the worm Monet", jokingly calling them the art masters of folding wings.
's the purpose of Irene's doing so is not difficult to understand.
is an interesting way to get people to learn more about the role of flies in the biological world and to identify the life cycle of flies.
even if they are annoying, even many people's nightmares, can not ignore their benefits to humanity.
after all, it's hard to think of this disgusting bug, but there's so much to be nice about.
