The first **, in the process of growing, the rice itself carries insect eggs, and during the processing of rice noodles, the adults are killed, but the eggs are not killed.
The reason why the eggs do not multiply into larvae quickly is that the growth and development of the eggs require the participation of water, and the eggs will hatch into larvae when the rice is at the right temperature and humidity.
Normally, when the temperature reaches more than 20 degrees Celsius and the humidity reaches about 65-95, the eggs can hatch.
The nutrients in the rice can fully meet the growth needs of the rice worm, the scientific name of the rice worm is the rice elephant, and the larvae are white flesh worms like maggots, and then slowly pupate into moths.
Moths fly to other foods according to their sense of smell, so when you see a large number of moths in your home, most of them are food "worms".
The second**, during transportation and storage, was contaminated by insect sources. Rice that has lost the protection of its husk and cortex is easily polluted by the environment, so many people in rural areas will take out the rice and expose it to the sun when the sun is good to prevent insects and insects.

When ginseng is damp, it will naturally grow insects in hot weather. It should be placed in a cool, dry place, preferably thoroughly dried ginseng in a small packet with a desiccant inside.
The main insect pests that harm ginseng are: needleworm, mole cricket, grub, ground tiger and grass borer. They are widely distributed, miscellaneous, and harmful, and the ginseng is pore and notched and susceptible to disease-causing occurrences, thus greatly reducing the yield and quality of ginseng.

1. One is infected with eggs when the rice has not yet been processed; The other is infected with eggs during processing or storage.
2. Because there are eggs laid by insects in the soil.
Insects that live in the soil: These insects feed on the roots of plants and the humus in the soil. Due to their activity in the soil and their gnawing on plant roots, they are a major pest in agriculture, fruit trees and seedlings.
These insects are the most afraid of light, and most species have poor activity and migration ability, rarely burrowing into the ground during the day, and the most suitable time for them to be active is at night and on rainy days.

After the organic matter is broken down by bacteria, only the worm daughter cells are produced, and finally become worms.

This is because the rice has been contaminated with insect eggs during the processing process, and insects will give birth when the rice is wet.
-
It is produced by the reproduction of bacteria in the rice. The rice in the rice jar has not been washed, there are more bacteria, and there is no influence of the external environment, so insects will naturally grow. Therefore, the rice in the rice jar should be washed several times, and there are more bacteria.
-
There are two main ways for rice to produce worms: the first is that the rice is infected with different eggs before it is processed and packaged, and after a long time, the eggs develop and produce worms. The other is that rice will be contaminated with different eggs after being opened at home, such as flies, so different rice may also give birth to different insects.
-
How are there insects, all kinds of insects are also a kind of animals, animals are able to reproduce, mainly oviparous reproduction, female insects and male insects mate, after a certain gestation period will lay eggs, and when the temperature and humidity are suitable, the eggs will hatch larvae, slowly grow up through eating, such as various insects, praying mantis is to lay eggs in autumn, and hatch small mantis in the spring of the next year.

Bugs will grow after food rots, but this phenomenon is limited to unsealed environments, and if it is in a sealed environment, bugs will grow!
Generally speaking, food does not contain eggs, but after opening the package, it will be transmitted through the air or the insects themselves, resulting in a certain amount of eggs in the food. If the food is left for a long time, the bacteria inside the food will quickly multiply with the help of the food, resulting in the phenomenon of decay. Food rot and worms are actually two different things, but there is a certain correlation!
In normal times, bacteria multiply and release a lot of heat, and these calories are just needed for insects to break eggs! At this time, the bacteria are multiplying rapidly, and the larvae of the insects are also slowly multiplying, which generally occurs in the inside of the food, and the internal decay cannot be observed on the outside due to the cover of the epidermis, so generally everyone can no longer eat when they see the food rotting, in fact, all this has been carried out a long time in advance, but it was not discovered in time!
When bacteria and insects multiply to a certain extent, it is time to break through the epidermis to give people a feeling of decay, many people feel that the insects are added later, in fact, this is all due to the reproduction of bacteria and insect larvae!
In daily life, try to seal the food as much as possible, because bacteria need a certain amount of oxygen to multiply, and bacteria cannot multiply normally in an oxygen-free environment. The food itself does not contain insect larvae, and sealing it can effectively reduce the addition of insect eggs! At this time, even if the food is opened, it will multiply uncontrollably due to the reduction of these two factors, and the food will not rot for a long time in a sealed environment!
But all this is not to ensure that the food must not rot, the seal is only to ensure that the food rots and deteriorates slowly, when the food is placed for a certain date, as long as the food has been in contact with the air, so long can not prevent the bacteria in the air from contacting the food, and it is impossible to prevent the food from rotting, so try to use it as soon as possible after opening the package to prevent the food from rotting and growing worms!
-
Food decay will produce a lot of microorganisms in a non-closed state, and these microorganisms will contain a certain amount of eggs in the food through the attachment of insects such as air or flies, and these eggs will multiply through rotten food and eventually grow into worms.
-
The food itself does not carry insects, but when it comes into contact with the air, there are many microorganisms in the air, and it is possible that the insects themselves spread and attach to the food, resulting in the growth of insects.
-
When the food rots, flies and bugs and the like lay eggs in there, and after a while the bugs come out inside.
-
Completely sealed will not breed bugs, and unsealed and breathable will breed bugs.
-
It is through the growth of some bacteria in the air, plus some of its own smell, it will have a peculiar smell. If you can't finish eating, be sure to put it in the refrigerator in time.
-
Usually the bugs are attracted to them, or lay eggs on things. The hatching worms feed on decaying things.
-
Many insects lay eggs on top of rotting things and hatch quickly.
-
First of all, to be clear, bugs do not grow through any reaction or out of the air, and the theory of spontaneous occurrence has been denied for a long time.
One such experiment can be done by covering the fruit that is beginning to rot with a net so that it cannot touch any bugs, and after a while it will be found that the fruit has not had any worms after rotting. The process of giving birth to bugs is as follows: the fruit rots, then the bugs lay eggs on the fruit, and finally the worms are produced.
In fact, this experiment can not be done, think about the rotten fruits in the refrigerator and in the fruit box, aren't there no raw worms?
-
Why do summer food grow worms when it is left for a long time, and how do those worms come from?
Some bugs are formed by eggs that cannot be seen, and if they are left in an open environment for a long time, they will attract bugs to lay eggs.

Generally speaking, there are two reasons: one is that when the grain is still in the field, it carries the eggs of rice worms. After being processed by the grain factory, it still sticks to some of the rice.
And the eggs are so small that they are not visible to the human eye at all. The eggs hatch into small insects in the summer heat, and there is its favorite rice around, so it eats a lot and reproduces quickly. Another reason is that every household buys rice every year and grows insects every year.
Some insect eggs are hidden in the bottom of the rice tank, the cracks of the rice bags, the cracks in the walls, and the cracks in the ground, and it is difficult for people to remove them one by one.
Rice has the highest starch content, followed by protein. In general, rice does not grow insects and becomes moldy (a large number of molds). Because the water activity value in rice is very low (i.e., very little water), and the presence of water is required for the growth and development of mold and eggs.
Low water activity values, molds and eggs do not absorb water. When the water activity value increases after moisture, mold and insect eggs will absorb the water in the rice and then decompose and apply the nutrients in the rice.
Put a few cloves of garlic in the middle or at each end of the rice bag, or wrap some peppercorns in a cloth or paper and place them in a container for rice. Usually the jar or bucket where the rice is stored should be cleaned to prevent the pupa of the winter from hiding inside. Once the rice worms are found, the rice can be dried in a cool place to let the worms fly away or crawl out, and the rice with raw worms can be eaten after being dewormed.
Do not expose rice to the sun.
There are also methods:
Method 2: Prepare a few small pieces of clean gauze, wrap each piece with a little pepper seeds, tie it and place it in the rice. If you use a rice bag to fill rice, you can soak the rice bag in boiling pepper juice for 10 minutes, and then dry it before holding rice, which also has an anti-insect effect.
Method 3: Put dried kelp or dried orange peel in the rice, which can play a role in preventing moisture and mildew at the same time.
If the rice has worms, you can use fresh ginger in the rice to drive the worms out.
In addition, in fine weather, it should be taken out to dry more.

There are eggs in the seeds, and when they are damp and left for a long time, the eggs come out in the right environment.
-
Some insects have very small eggs, you can't see them if you don't look carefully, and some eggs are laid into the food by the mother before harvesting, just wait for the right time and the right environment to break out of the shell! So we have this question: how can you give birth to worms if you don't see the eggs?
-
If there are absolutely no eggs, there will be no worms.
It's just that at some point, or at some point, there are already eggs, and you don't realize it. Because some eggs are very powerful.
-
Because food also contains microorganisms, organic matter, and so on, under the right conditions, life will be produced.
-
Actually, there are eggs, but more of them are in there, and you can't see them.
-
Maggots found on carcasses are not "born" from animal carcasses. Maggots are often found on carcasses because the smell of dead animals attracts flies to gather on carcasses shortly after death. The swarming flies lay their eggs on the carcass, and over time, these eggs develop into maggots.
-
1.The rotting flesh emits a smell that attracts flies, which come here to lay eggs, which hatch and become maggots. 2.
The eggs are laid by flies, and organisms cannot appear out of thin air. 3.Flies lay their eggs on the surface of their bodies, and after hatching, maggots burrow into the carcass.
Hope my answer will be helpful to you!
-
Maggots are the larvae of flies, and the animals will rot after death, while flies are scavengers, and their offspring are also scavengers, and when the flies' eggs settle on the corpses, they hatch out, and they are maggots.
-
Maggots in animals are mainly left behind by fly bites. These maggots are born from under the skin. As for why maggots are present, it is due to the fact that the carcasses of animals after death bring good nutrients for maggots to survive. It is ideal for animals such as flies to lay their eggs.
-
After the animal dies, it will be decomposed by something, and the decomposition product is maggots, these maggots are produced because there are some bacteria on the animal, the animal is not dead when the body is often washed, there will be no maggots, once it dies, the bacteria on the body are not effectively cleaned, maggots will be produced. Bonus points.
-
Most of the insects are oviparous, a few are in addition to the oviparous self-growing, the eggs are large and small, one egg and one worm or one egg and many worms, and the gestation period is mostly 3 days to one month.
