Good beans, why do they have worms? Where do bugs come from?

Generally speaking, there are two reasons: one is that when the grain is still in the field, it carries rice worms.

of eggs. After being processed by the grain factory, it still sticks to some of the beans. And the eggs are so small that they are not visible to the human eye at all.

The eggs hatch into small bugs in the summer heat, and there are beans around it, which is its favorite food, so it eats more and reproduces faster. Another reason is that every household buys beans every year, and insects are born 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.

Here's why.

The main causes of bean insects are as follows:

1.Failure to dry and store in time leads to excessive moisture in the beans, which becomes a breeding ground for insects.

2.The storage environment is not good, such as too high temperature, serious rodent infestation, etc., in this environment, the reproduction rate of insects such as borers is accelerated.

3.Stored for too long, because the beans have a limited lifespan, too long can cause the beans to dry out and spoil, making them more susceptible to insect erosion.

4.If the beans are not cleaned and left for a long time, there will be a lot of food residue on the surface, which is one of the places where insects breed in large numbers.

Among these reasons, the insects are mainly flying eggs in the environment or eggs in food scraps. When the temperature around the beans reaches 20 -40 ° and the humidity reaches 65°-95°, the eggs hatch and the beans provide sufficient nutrients for the insects, so they can reproduce smoothly.

When wet, insects will grow.

Put it in a plastic bottle. The plastic bottle that usually drinks is larger, and it is better to wash it and dry it. Pick the beans you bought, pick out the rotten beans with insect eyes and mutilation, and pour the remaining beans into a plastic bottle, and put the cap tightly in a cool and dry place, so that there will be no insects all year round.

Place in the freezer to freeze. If you find that the beans at home have worms, if the worms are not serious, pick up the beans of individual worms, and put the remaining beans in the refrigerator freezer, and cryopreservation can also make the beans not regenerate worms.

Exposure to the sun. There are some fluff things on the beans, indicating that the beans have been put for too long, and they need to be taken out and exposed to the scorching sun.

Beans are a family of dicot plants, woody and herbaceous plants, such as "red sandalwood", "locust tree", "soybean Xunchun", "mung bean", "red bean", "pea", "peanuts", etc., collectively referred to as leguminous plants every day, and also refers to the seeds of these plants: legumes, beans, bean pods (beans), soybean milk, beans are green, boiled beans are burned, and eyes are like beans.

A fruit of the bean plant. The types of beans include soybeans, broad beans, peas, green acres of beans, kidney beans, adzuki beans, etc. Soybeans are divided into different colors according to:

Soybeans, black beans, green beans, etc. Kidney beans can be divided into: lentils, kidney beans, sword beans, green beans, cowpeas, etc., and the colors of adzuki beans are red, yellow, light green, gray, white, tea, etc.

1. In fact, in the process of grain production and processing, storage pests may lay eggs in it, depending on the follow-up treatment.

2. For example, in the process of bean processing, high-concentration carbon dioxide treatment for several days can make insects die of lack of oxygen 3. There are two kinds of insects or miscellaneous grains sold in supermarkets.

One is vacuum, and the other is filled with carbon dioxide and nitrogen.

These two kinds of insect and moisture-proof effects are good, of course, there are also plastic bags sealed without treatment.

The cause of bean insects is improper storage, and after harvesting, it is necessary to disinfect, kill insects and eggs, and also carry out storage sites such as warehouses.

Beans bought at home are best dried in the sun if they are to be left out for a while.

Three or five hours, [1) can remove water, will not mold in storage. 2) Kill the eggs that may be present. After the beans are cooled, put them in a plastic bag and store them in a cool place.

Easier way: turn in the microwave oven for a few minutes, feel a little hot (60--70), cool and then put it in a plastic bag to store tightly, the effect is very good.

After a long time, the beans become moldy, and that kind of thing makes the bugs like it, and bugs are born.

In summer, there are often small hard-shell insects flying in Chenchen's house, and my mother said that it was a worm in the beans, and Chenchen felt curious. My mother took out the basin containing beans from under the bed, opened it, and sure enough, there were many small black insects crawling on the beans, and there were holes in the beans. Why do beans have worms in the summer?

Actually, it's not the beans that have worms, but the worms that come in from the outside. This small insect is called the bean elephant, the bean elephant lays its eggs on the bean grains, and when the temperature is right, the larvae that hatch from the eggs grow while eating inside. When it's hot, it comes out.

Therefore, beans stored at home in the summer are the most susceptible to insects.
