What kind of worm is born in chestnut?

<> usually, chestnut chestnut weevil.

Fresh chestnuts such as chestnut moths and peach borers contain more water and nutrients, which are very suitable for insect growth. Usually, there are some insects after the chestnut flowers have faded and before the fruit sets fruit. When the worm eggs grow into larvae, they slowly grow by eroding the chestnut fruit.

Then, when the larvae mature, they burrow out of the chestnut's hole. These worms are usually flat chestnut weevils, chestnut-eating moths, peach borers, etc. It usually survives all the time.

Due to the high moisture content of fresh chestnuts, the respiration intensity is relatively high under the right environmental conditions, so the small insects growing in the chestnuts do not die due to suffocation. Generally, worms lay eggs until the larvae hatch and the adults come out of the chestnut shells. This process takes about 3 months, after which the adults dig out of the chestnuts and build a house for the ground in the winter.

How do you get rid of bugs in chestnuts? Soaking method: If there are insects in the chestnuts, you can soak them in water and sprinkle some salt in the water.

After some time, you will find some chestnuts floating on the water, and the insects in the chestnuts will float automatically. These chestnuts that float on the surface of the water are usually chestnuts with wormholes. They can be selected, and then the remaining chestnuts can be washed and eaten.

If long-term storage is required, it is recommended to dry the surface of the washed chestnuts. Drying, otherwise too wet will shorten the shelf life of the chestnuts.

Are bugs in chestnuts poisonous? Can you eat chestnuts with bugs? It is non-toxic, but it is not recommended.

The insects that grow in chestnuts are generally non-poisonous and do not produce toxic substances, therefore, eating insects after removing chestnuts does not have a significant impact on human health. However, if you find worms in chestnuts, you may feel psychological discomfort, and since worms feed mainly on the fruits of chestnuts during development, they also lose nutrients. If you feel sick, then it's best not to eat anymore.

The most common insect in chestnuts is the peach heartworm, a larva of a moth-like insect that is the most common pest of fruit trees. In addition to the Rosaceae fruit tree, apples, pears, peaches, etc., chestnuts are also the favorite food of this pest.

Chestnuts may have insects, and chestnut weevils and chestnut moths are the two more common ones.

This insect is called the chestnut elephant worm, and this insect can also harm the growth of chestnuts, and their vitality is particularly tenacious.

In the chestnut flowers, when the fruit is just beginning, the insect will lay the eggs in the new fruit, because the new fruit is more tender in appearance, the insect is easy to penetrate, and then after a period of growth, the fruit is ripe, the seed coat is healed, so the appearance of the chestnut does not leave traces, when the picked chestnut is stored for a period of time under the right temperature and humidity conditions, the eggs will slowly develop, grow into larvae, which will cause the chestnut worm to grow out of it.

Chestnut contains more water and sugar, rich in a variety of nutrients, very popular with insects, in the chestnut flowers, just beginning to bear fruit, insects will lay eggs in the new fruit, because the appearance of the new fruit is more tender, insects are easy to penetrate, and then after a period of growth, the fruit is ripe, the seed coat heals, so the appearance of the chestnut does not leave any traces, when the picked chestnut is stored for a period of time under the right temperature and humidity conditions, the eggs will slowly develop, grow into larvae, This also leads to the chestnut insects we see are simple and practical, and the effect is good, everything is really too limited by a person's strength and cognition, knowing that the delicious chestnuts are not insects in the later stage, but when they bloom, the flying insects lay eggs on it, and when the chestnuts are ripe, the insects also grow up in them and crawl through their eyes.

Simple and practical, with good results, there is always one for you!

This method is generally considered to be the best method, similar to the practice shared by Yueyue before, that is, it needs to add another step, after the chestnut is bought, it is spread out in a cool and ventilated place, let it blow for 3-4 days, and then wash it, let it boil in the pot for 3-4 minutes, cook until it is half-cooked, take it out and dry it to room temperature, and then put it into a fresh-keeping bag and seal it, and put it in the refrigerator to freeze it, so that no matter how long it will not be bad, it will not be bad, and the chestnut will be dried first, and then steamed and then saccharifiedIt tastes very sweet.

This second method is more suitable for preserving the freshest chestnuts, freshly picked fresh chestnuts, the fresher the better, the best is the freshly peeled chestnuts, no need to peel off the shell, no need to dry or dry, directly packed in a bag, put it in the refrigerator freezer, put it in the New Year and just picked it up, quite a lot of netizens also think that this method is good, but now the chestnuts are peeled in advance to sell, we don't know if it's new or not when we buy it, if you come across the kind of chestnuts that are piled up into a hill and peeled and sold, After buying it back, you can save it this way!

1. There is parasitism of insect eggs.

In fact, the chestnut itself will not give birth to insects, but it is indeed easy to grow insects, mainly because the chestnut is easy to parasite eggs, the chestnut actually has a hard prickly shell outside when it grows, when the chestnut slowly matures, the thorny shell will be broken, at this time the adult will shovel the eggs on the chestnut, and at this time the shell of the chestnut is relatively tender, the insect hatches into the chestnut, after a period of time the original shell becomes hard, and the insect remains in the chestnut, so it is easy to find the chestnut worm after returning home.

Why are chestnuts prone to worms? Why are chestnuts so easy to spoil? (2) 2. Chestnuts are difficult to preserve.

It is indeed easy to break, many people buy the original home and either find that the worm is rotten, that is because the chestnut is difficult to preserve, the chestnut is afraid of heat, afraid of dry, afraid of wet and afraid of freezing, so many people do not know how to preserve chestnuts, especially fresh chestnuts, can not be put for a long time. If you just put it for a few days, you can directly put the chestnuts in a ventilated and dry place, do not seal the chestnuts first, and do not expose them to the sun, although the exposure can kill insects, but it will nourish the taste of the chestnuts. If you want to store it for a long time, seal it in a plastic bag and put it in the crisper compartment of the refrigerator.

3. Warm reminder.

If you find that the chestnut is wormed, don't eat it, although it is said that eating it will not cause any great harm to the human body, but after all, it has been destroyed by insects, and most people can't eat it when they look at it.

Chestnut is a fruit that is more prone to insects. Improper storage can easily lead to insect bites.

As for the reason why chestnuts are bitten by insects, it is actually very simple: it is so rich in nutrients.

Chestnuts themselves are extremely rich in nutrients.

Specifically, chestnuts mainly contain the following nutrients:

Protein. Fat. Dietary fiber.

Vitamin. Carotene.

Carbohydrates.

Calcium, iron, potassium, sodium and other trace elements.

At the same time, chestnuts also contain very high calories.

Because of its rich nutrients, chestnuts are known as the "king of dried fruits". It is even known as "ginseng fruit".

Because it is rich in nutrients, chestnuts are an important food for many animals**. This is also the fundamental reason why chestnuts are prone to insects.

We all know that squirrels like to eat dried fruits, including chestnuts.

In fact, in addition to animals such as squirrels, insects also like to eat chestnuts. ......The insects that grow on chestnuts are actually the larvae of insects. ......After hatching on the chestnut, they feed on the chestnut and rely on the rich nutrition of the chestnut to keep growing ......

Therefore, chestnuts themselves do not grow worms. ......It is the rich nutrients contained in the chestnut itself that attract insects to run over, so that the chestnut grows worm ......

In fact, it's not just chestnuts that are prone to insects. ......As long as the fruits and seeds contain nutrients, they are prone to worms.

Therefore, it is more appropriate to say that these fruits and seeds are more insect-bearing because of the nutrients they contain that attract a variety of animals, including insects.

1. Why do chestnuts grow worms from the inside?

The reason for the growth of worms from the inside is that before the chestnut is mature, the chestnut worm has already laid eggs inside, and when it comes to a certain time, under the right temperature and moisture, the worm will hatch, so there will be worms when the chestnut is opened. The way chestnut worms lay eggs is to bite an oviposition trough into the chestnut bract, lay the eggs in the trough, put the eggs to the bottom of the trough, and then plug the holes, the eggs can have a certain living space, and the ovaries are generally relatively small, and the chestnuts can also heal themselves in the growth process in the later stage, so it is not easy to see whether there are insects in the end.

2. Can chestnut worms still be eaten?

It is recommended not to eat.

In the case of chestnut worms, it is estimated that most of the meat in it has been eaten by chestnut larvae, and the meat quality that has been eaten is generally contaminated, and the meat texture will become very pink or dark, and the nutritional value will be lost, and there may be some substances that are not good for the body.

And generally if you see long insects, you may also have a certain degree of resistance, even if you get rid of the parts that have been eaten by insects, you still don't feel at ease when you eat them, so it is recommended not to eat them.

Chestnuts themselves do not produce insects. But foods that are high in starch and fat are prone to worms.

However, the insects in chestnuts are often parasitic in the fruit of chestnuts in the form of eggs before they are picked, so the key to not giving birth to insects lies in how to kill the parasite eggs inside and some existing preservation methods, which are to try to make the eggs in the chestnuts not grow further. And the most effective way to prevent chestnut insects is from the source.

First, be sure to dry it. Especially when exposed to the sun, be sure to turn it many times to allow the water to fully volatilize. At the same time, turning it several times will help the chestnut to peel (referring to the red hairy skin inside) in the future

Second, if you need to keep it for a long time, it is best to seal it in a plastic bag and vacuum pack. For general storage, seal it in a plastic bag and then place it in a dry and low temperature place (of course, the inside of the refrigerator is the best).

Never treat it with boiling water, as the meat inside will turn black!

Chestnut pest control methods.

Peach borer. The larvae eat chestnut seeds, and the insect feces in the seeds are full, which is inedible, and causes fruit drop, which has a great impact on the yield and quality.

Control method: From late July to late August, the first generation of adults is in full bloom, spray with 600 times of 30% insecticidal moth emulsifiable concentrate, and the control effect is better.

Chestnut weevil: also known as chestnut elephant, the damaged fruit loses its edible value and germination ability.

Prevention and control methods: one is to stack and thresh on the cement floor, so that the larvae that have lost fruit can not enter the soil, and they can be killed in a centralized manner, or in advance in the chestnut stacking site, 30% phosphine is sprinkled, and the control effect is excellent; The second is to use the feigned death of the adult insects, when the dew is not dry in the morning, lay a plastic film under the tree, tap the branches, and kill the adults; the third is to spray the fruit buds with 50% pine borer emulsion after harvesting at the appropriate time; Fourth, fumigation of chestnut with carbon disulfide, when the temperature is above 20 degrees, 20 mg of medicine in 1 cubic meter of space, treatment for 20 hours, can kill the larvae, and has no effect on chestnut.

Chestnuts contain more water and sugar, rich in a variety of nutrients, very popular with insects, in chestnut flowers, when the first fruit, the insects lay eggs in the new fruit. So chestnuts are prone to insects.

Due to the tender appearance of the new fruit, the insects can easily penetrate it, and after a period of growth, the fruit matures and the seed coat heals. Therefore, there are no traces left on the appearance of the chestnut, when the harvested chestnut has been stored for a period of time under the right temperature and humidity conditions. The eggs slowly develop and grow into larvae, which leads to the chestnut worms we see growing from the inside.

If the fruit of the chestnut is not rotten, then the chestnut worm can still continue to be eaten after being removed, but some people may not be very comfortable psychologically; However, if the chestnut with insects has been blackened and rotten, then it is not recommended to eat, such chestnuts not only taste worse, but also may breed a large number of bacteria, and it is easy to produce uncomfortable reactions after eating.

This is related to the origin, variety, growth environment, and management method of chestnut.

The most common insect in chestnuts is the peach heartworm, a larva of a moth-like insect that is the most common pest of fruit trees. In addition to the Rosaceae fruit tree, apples, pears, peaches, etc., chestnuts are also the favorite food of this pest.

We usually think that chestnuts are susceptible to insects, but it is usually said that chestnuts that have no insects have grown insects after being stored for a period of time. These bugs certainly don't appear out of nowhere. There is also a layer of thorns on the outside of the chestnut shell, and the cracking indicates that the chestnut is ripe.

It is only when the outermost prickly back shell is opened that the adult has a chance to lay eggs on the inner shell of the chestnut (which is what we usually see), and it takes a certain amount of time for the hatched larvae to burrow into the fruit, so the insecting phenomenon usually occurs after we buy fresh chestnuts and store them for a while.

The main chestnut producing areas in China are Yanshan, Taishan, Huashan, Huangshan, Taihang Mountain, etc. The chestnut fruit in the Taishan Mountains is the largest, but it has the worst taste and is the most susceptible to insects. The chestnuts of the Yanshan Mountains are the best, the taste and nutritional value are the best, the least likely to have insects, and the highest.

The Qianxi chestnut and Huairou chestnut we usually see are all produced in the Yanshan Mountains. However, in the Yanshan Mountains, chestnuts from Miyun in Beijing are more susceptible to insects than the surrounding Huairou and Changping, which is mainly caused by the variety of chestnuts, the ecological environment (natural enemies, climatic conditions) and the management mode of fruit trees. If you are lucky enough to buy chestnuts from Jixian County, Qianxi, Beijing, Huairou and Changping, then you will find that even if you put the chestnuts to mold or crack, they will not have insects.

Storing chestnuts in a ventilated and dry place, avoiding exposure to the sun and being airtight, is a good way to reduce mildew and insects. Of course, after a long time, it will also lose water and make the flesh from crisp to tough, and raw food is another taste. Give it a try.
