Why do rice worms appear out of nowhere?

Rice worms are also ordinary insects, mainly adult rice worms put their eggs into rice, and when the eggs develop and break into larvae, they become rice worms.

Because if the rice is stored for a long time, insect eggs will appear. Then the rice worm will hatch.

There are generally two reasons for the presence of rice worms in rice: one is that when the grain is still in the field, it carries the eggs of the 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.

Ways to prevent rice worms:

1. Oxygen-free preservation method: first spread out and dry the rice to be stored in a ventilated place (note that it should not be exposed to the sun) thoroughly, and then put the rice into a non-toxic (food) plastic bag with less air permeability (it should be full), tie the bag tightly, and put it in a cool and dry place, so that the rice can be stored for a long time.

2. Zanthoxylum pepper insect prevention preservation method: Zanthoxylum pepper is a natural antioxidant, with a special fragrance and insect repellent effect. The specific method is to put 20 to 30 peppercorns in the pot, add an appropriate amount of water (it is advisable to soak the rice pocket), put it on the stove fire to cook the fragrance of peppercorns, and then remove the pot from the fire, put the rice bag into the pepper water and take it out to dry, and then pour the rice into the pocket.

In addition, wrap a few small packets of peppercorns with gauze, put them on the top, middle and bottom of the rice bag, tie the bag tightly, and put the rice bag in a cool and ventilated place to prevent rice insects.

3. Moisture absorption and preservation method of plant ash: at the bottom of the rice tank, spread a layer of plant ash (it is best to put the plant ash in a gauze bag and put it at the bottom of the tank), and then pour in the rice to dry and blow through, and put the rice cylinder cover tightly, and place it in a cool, dry and ventilated place, which can be stored for a long time.

4. Kelp insect prevention and preservation method: Dried kelp has a strong ability to absorb moisture and has the effect of killing insects and inhibiting mold. When storing rice, mix rice and kelp in a ratio of 100:1, take out the kelp and dry it thoroughly after about 10 days, and then put it back into the rice, so that after repeating it several times, it can prevent rice mildew and insects.

There is stale grain in the rice grains, or the temperature and humidity of the storage space of the rice raider are high, resulting in the rice will grow rice worms.

Rice worms are the main pests of grain storage, mainly parasitic in old grains stored for 2 3 years, such as corn, rice, wheat, sorghum and flour and other grains, its adults gnaw on grain grains, and the larvae eat inside the grain. Due to its rapid growth and reproduction rate, it is very harmful, and its geographical distribution can spread all over the world, while in China, it is mainly distributed in the south.

When the temperature is higher, the reproduction is faster, and the adult worm has feigned death. It has the characteristics of clustering, moisture-loving, negative phototaxis, etc., and has strong fecundity. Life likes high temperatures, and the optimal temperature is 30 -33°C.

If the rice is to have insects, you can put the rice in a plastic bag and seal it, preferably with two layers of plastic bags (to prevent moisture from entering), and then put it in the refrigerator and freeze it for 24 hours, and take it out for consumption. Every month or so, the rice is frozen again in this way until it is finished. In this way, the rice will not have worms.

Rice is easy to keep for a long time.

bai raw borer, du should be eaten and bought as you go. After the rice is bought, it should be loaded into a rice bucket (cylinder) and placed in a rice bucket.

Put the upper volume inside. Four to five packets of peppercorns (10 grams of peppercorns per pack, and the bags are made of gauze), which can prevent moths; You can also put a clean wine bottle in the rice barrel, the mouth of the wine bottle is higher than the rice noodles, and the bottle is filled with 100 grams of liquor, which can also prevent moths; If you put some quicklime at the bottom of the rice bucket (the quicklime can be covered with a plastic sheet to separate the rice from the quicklime), or if you mix some garlic cloves in the rice, you can prevent moths. Regardless of the above method, the lid of the rice bucket must be tightly closed.

1.Freezing method.

If the rice is not very serious, you can put the rice together with the container containing the rice, put it in the refrigerator and freeze it for 24 hours and take it out.

Note that the freezing method cannot completely freeze the rice worms to death, and they will wake up once they recover to room temperature, so they must be picked out in time after freezing.

2.Sichuan pepper method.

Sichuan pepper is a natural antioxidant with a special smell, rice worms are sensitive to odors, and avoid this smell, prepare a few clean small gauze cloths to wrap Sichuan peppercorns.

Place in the rice box in the upper, middle, lower and other different positions, and then the rice box lid tightly on the good, pepper to choose the newly bought, strong smell, every once in a while, and so the taste of pepper has become lighter, and then replace the new pepper gauze bag on the line.

In addition, you can also take about 30 peppercorns and boil them into pepper water, soak the rice box in pepper water for 10 minutes, and then dry them naturally before using them to fill rice, which can also effectively prevent rice insects.

3.Liquor Law.

The ethanol volatilized in the liquor has the effect of killing viruses and insects, put a glass of liquor in the rice box, the mouth of the cup should be higher than the rice surface, let the liquor volatilize naturally, and then close the lid of the rice box, so that it can effectively prevent rice insects, but you need to pay attention not to knock over the cup.

4.Garlic method.

Put a few cloves of garlic in different places in the rice box, and then close the lid of the rice box tightly, the insect control effect is also very good.

5.Kelp method.

Dried kelp has a strong ability to absorb moisture, but also has the effect of inhibiting mold and insecticide, the dried kelp and rice are mixed according to the weight ratio of 1:100, and the kelp is taken out every 10 days to dry and then put back, a kelp can be reused about 20 times, so as to prevent rice mildew and insects.

6.Orange peel method.

The peel of the orange left over from eating the orange is dried and then placed in the rice, the taste of the orange peel not only repells insects, but also gives the rice a fresh fragrance.

7.Shade drying method.

Usually everyone likes to put the rice of raw insects, rotate in the sun for exposure, in fact, this is wrong, the exposed rice will affect the taste due to water dispersion, and the rice worms will increase unabated, the correct way is to put the rice in a cool and ventilated place, the insects in the rice will crawl out of the rice with higher temperature, and then the rice will be sifted.

Because the water activity value in rice is very low, and the presence of water is required for the growth and development of mold and insect 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.

Rice utensils should be clean and tight. It is best to place the rice in jars, jars, buckets, and have a tight lid. If you use a cloth bag for rice, you should put a plastic bag on the outside of the cloth bag and tie the bag tightly.

Soak the cloth bag in the boiled pepper water, put the cool-dried rice in the air-dried bag, and then wrap some new peppercorns with gauze, and put them on the top, middle and bottom of the rice respectively; Tie the bag tightly, so that it can not only prevent mildew, but also repel insects.

Why are there worms in rice? Rice worms come from ** again? I didn't understand it before, and reminded my family.

Because there are eggs in the rice, they will hatch into rice worms when the temperature is right.

The pupa of the insects that survive the winter are hidden in the jars or buckets where the rice is stored, and it is easy to grow insects in the summer.

The methods of insect control are: 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 put 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 placed in a cool place to dry, so that the insects fly away or crawl out. Do not expose rice to the sun.

In addition, there is a way to also have a way:

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 grown worms, you can use fresh ginger to put it in the rice to drive the worms out.

In addition, in fine weather, it should be taken out to dry more.
