Some people say that maggots come before flies, so what came first?

The universe gave birth to the earth, and life was born on the earth, and the first life was a single cell, and now it is almost all multicellular organisms, first chickens or eggs.

It has plagued us for many years, just as someone said that maggots come before flies.

So what came first? Flies as oviparous animals.

It shows that he evolved from oviparous animals, and mutation is most likely to occur in the juvenile period, so it is maggots that come before flies, which is a very esoteric philosophical question.

Flies can be seen everywhere in our lives, as long as there are leftovers at home, there will be their figures, their vitality is extremely tenacious, it is really the kind of creature that can live casually, flies as oviparous animals, he will lay eggs on nutritious animals or plants, so that its offspring have to eat after birth, but the first song has flies or flies have maggots This question has been bothering people, I don't know that there were oviparous animals before flies, and flies are constantly evolving. Biologically speaking, genetic mutations are most likely to appear in children, that is, maggots laid by flies, but the maggots that give birth to this maggot are not called flies, they can be called the ancestors of flies.

Whether it is maggots or flies, we don't want to encounter in life, it has been reported in many news, when eating fried chicken, the maggots inside are rolling and flowing, just like a group of "children" waiting to be fed, frantically gnawing on chicken, you can imagine when people eat this kind of chicken, how a disgusting, want to be healthy and hygienic conditions must meet the requirements, a restaurant without health guarantee is not worthy of catering.

In the eyes of many scientists, the larvae of flies are a very nutritious substance, their whole body is full of protein, it can be said that a few maggots can be worth a glass of milk, but the maggots used are specially cultivated artificially, not public toilets.

The kind inside, in our cuisine, has silkworm chrysalis.

And bee larvae this dish, their ** is still expensive, but those who have eaten it will applaud.

Fly. Because flies are evolved, and maggots can only be spawned by flies, they are the flies that came first.

This is the same as the chicken or the egg, I think it is maggots first, because we can often see the appearance of flies in the toilets in the countryside, so I think he should be the first.

The ancestors of flies are maggot-like larvae or adult worms of flies. So the possibility of maggots being there is much greater, maggots are the larvae of flies, and only flies lay eggs are likely to occur, and the problem is the same as whether there is a chicken or an egg first.

It is difficult to explain, but it can also be inferred that the ancestor of the fly was a larva similar to maggots or an adult of a fly, so it is more likely that maggots were present first.

Since maggots have grown, they must have been contaminated with the eggs of flies, there is no doubt about it. Importantly, this process of contamination may be done unconsciously. Because theoretically, maggots are eggs laid by flies in food, and maggots would not be born without flies.

However, it is not excluded that there will be other parasites or bacteria and viruses.

Maggots hatch from the eggs of flies. Because the eggs of flies are too small for people to see, they mistakenly believe that maggots grow on their own. Maggots, also called flies, are the larvae of flies, so maggots should not be produced without flies.

Maggot Hazards:

Maggots mature and turn into flies, etc., which feed on garbage heaps, toilets, rotting animal carcasses, pus, blood, sputum and vomit. It carries tens of thousands of bacteria, viruses and parasite eggs on its body and abdomen. Flies have the habit of eating, spitting and pulling, and he flies down to **, ** food and utensils will be contaminated by bacteria, viruses, and insect eggs, and when people eat contaminated food or use contaminated utensils, intestinal infectious diseases or parasitic diseases can occur.

There are no reasons why flies can give birth to maggots:1. The items in the house are not original in the house, but are invited from other places (bought, borrowed, or given), so that the items are in another place, and the fly egg-laying work is completed. It's just that the time is a little shorter, and the maggots haven't grown.

I grew up in my own home and found out.

Second, the range of human vision is limited, and it is likely that there is a fly waiting to lay eggs at home. Or rather, flies from outside, after laying eggs, fly away for some reason. Missing. This has caused the matter of why there are maggots in the house when there are no flies.

Ways to prevent maggots:1. Environmental prevention.

Adopt a variety of methods to limit the breeding of flies, such as removing garbage, faeces, and household garbage in a timely manner.

Bagging, composting.

and biogas fermentation, etc.

2. Physical prevention.

Kill larvae and pupae by drowning, smothering, fishing, boiling, composting, etc.; Adult flies are killed by direct swatting, fly trap trapping and sticky paper sticky trapping. Install screen doors and windows to prevent flies from flying into the room.

4. Biological prevention.

Natural enemies of flies and pathogenic organisms, such as parasitic wasps, should be used to kill flies.

Parasitic on fly pupa. Bacillus thuringiensis.

The exotoxin of H-9 kills fly larvae.

This maggot is the offspring of the fly. When a fly is about to die, if there are larvae in its body, it will give birth to them as soon as possible. I've encountered this phenomenon several times, I hit flies with rubber bands, I just don't want to kill them, and then burn them in the daylight with a magnifying glass.

That's why I discovered the above phenomenon. Small maggots die when they are focused by a 6x optical magnifying glass, and large flies are also with the smell of burnt proteins.

The larvae of flies are called maggots.

Maggots prefer to live a few centimeters below the surface of their food. The food of fly maggots consists of livestock droppings, garbage, and some decaying matter. Maggots are very active, from the moment they hatch, they are constantly stirring around, constantly burrowing around, and they are also strong light-proof and social.
