How to identify rice worms and bugs? What kind of bug is a rice bug?

Hello. Rice worms.

The scientific name is rice elephant.

Rice and other cereals at home are most likely to have rice elephants.

<> meter elephant.

According to your description, it may be rice worms in your home

Rice worm is a borer in rice, the scientific name is rice elephant, often found in cereals, because of the rapid reproduction, is one of the main pests in cereals. Its main host is corn, rice, wheat, sorghum, flour, and other stored grains, and there are many families with wooden floors.

Adults mainly overwinter in the dark and damp brick and stone crevices in the warehouse, and can also overwinter in loose soil, bark and ridges outside the warehouse. In mid to late May of the following year, the overwintering adults begin to move, and the adults who overwinter in the barn continue to lay eggs and reproduce on the spot.

Part of the adult overwintering outside the warehouse moves into the warehouse, and the other part flies to the field, lays the eggs on the ears of wheat, when the adults lay eggs, they eat the wheat grains with their mouths, form an egg nest, lay the eggs in it, and then secrete mucus to seal, and the egg period is 7-16 days.

From mid to late June to early to mid July, the larvae hatch, mothed into the grain, the larval stage is about 30 days, the pupation is in mid to late July, the pupal period is 7-10 days, the adult emerges in early August, the adult has feigned death, likes light, temperature, humidity, strong fecundity, the female can lay about 500 eggs, the temperature is lower than 15 in early October, and the adult begins to overwinter.

Rice elephant is one of the important storage pests, mainly for the storage of 2 3 years of old grain, strong reproductive ability, large appetite, so it has caused huge losses to grain storage. The main prevention and control methods are as follows

1. Improve grain storage conditions, keep warehouses clean, plug gaps to prevent rice elephants and other storage pests from entering, so as to reduce the harm to grain;

2. Improve storage technology, such as using plant ash, plastic film or kraft paper to isolate and store pests. If an insect infestation has occurred, the rice elephant should be driven out of the grain by exposure, so that the pest is separated from the pest-free grain;

3. Kill by spraying chemicals or phosphine fumigation;

4. If the amount of grain preserved is small, you can also use insect-proof packaging or add long-term odor insect repellent to the packaging bag to protect the grain from rice elephants.

There are two types of rice worms, namely rice elephants and rice moths.

1. Rice elephant. Commonly known as the stalk, it belongs to the Coleoptera weevil family and is the main pest of stored grains. Adults feed on the kernels, and the larvae eat the inside of the grains. Harm rice, rice, wheat, corn, sorghum, etc.

The rice elephant is a small black beetle in the rice valley, commonly known as the scorpion. The main host is corn, rice, wheat, sorghum, flour, and other stored grains. There are also more homes with wooden floors.

2. Rice moth. The insect name belongs to the order Lepidoptera, the family Wax borer. Found on rice, wheat, corn, millet, peanuts, sesame, dried fruits, etc. The larvae like to inhabit broken rice, and spin silk to connect the broken rice to form a long cylindrical cocoon.

1. One reason is that when the grain is still in the ground, 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.

2. Another reason is that every household buys rice 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.

3. 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.

The rice worm is the egg of the rice worm when the grain is still in the ground, and it is still stuck to some rice after being processed by the grain factory, and the eggs are very small, and the eggs hatch into small insects in the high temperature in summer, and there is its favorite rice around, so it eats more and reproduces faster. Rice worm is one of the important storage pests, mainly for the storage of 2 to 3 years of old grain, strong reproductive ability and large appetite, so it has caused huge losses to the storage of grain. The control of rice insects requires improving grain storage conditions, keeping warehouses clean, blocking gaps to prevent the entry of rice elephants and other storage pests, so as to reduce the harm to food, and also improving storage techniques, such as using plant ash, plastic film or kraft paper to isolate storage pests.

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.

It is a leaf mite, and the other is a red one called a red spider, and they are all mites.

The extermination is handled as follows:

1. First of all, install a window screen with more meshes, which can effectively prevent insects from flying into the home.

2. Secondly, if the insects have come in, it is not easy to kill, you can concentrate on cleaning up, turn off all the lights in the house at night, only turn on a balcony light, and wait for the insects to gather over, spray it with mosquito killers.

The rice spreads out in the sun, preferably at noon when the sun is very hot, at this time, the rice worms will all run away, or it will be gone for a long time.

2. Sprinkle some quicklime powder on the place where the worms grow (on the back side of the mat) and remove them after a few hours.

Fourth, the mat can be placed in the bathtub soaked in water, add 3% salt or alkali, bleaching powder, lime, etc. to the water, and soak for 24 hours to prevent moths.

Put some soapy water in it to make it sticky, and they will hit it and get stuck to death.

Rice insects are generally said to be grain storage pests, there are more than 200 species, and there are 3 common types of 1, moths. Indian grain moth, a little grain moth, wheat moth, corn borer, pink spotted borer, etc. 2, beetles. Corn elephant, red grain thief, miscellaneous grain thief, saw grain thief, rice elephant, mealworm, black mealworm, black fungus, large grain thief, etc.

3. Mites.

1. The body length is about millimeters, the width is about millimeters, the body shape is oval, the body color is reddish-brown to asphalt-colored, and its back is dull or very dark. The head is very small, the notch is more obvious, the muzzle is slender, similar to the trunk of an elephant, the muzzle of the female insect is more slender than that of the male, and slightly curved downward, with a certain luster, while the muzzle of the male insect is short and thick, not curved, and the back of the snout has a thin line of longitudinal protrusion and obvious small notch points, which is dull.

2. The front end of the frontal part of the rice elephant is flattened. The base of the beak is thicker. The antennae are knee-shaped, rounded at the apex, and are 1 3-1 4 processed at the base.

The prothorax is wider than the head, about equal in length and width, broad at the base, and narrowed and tapered forward, and the back is densely covered with small rounded notches. The elytra are also densely dotted, each with an erect scale, 2-4 light red or orange-yellow colored stockings on the elytra, and each elytra has an oval markings at the base and slope of the wings, parallel on both sides, and the rows are slightly wider than between the rows. The leg joints appear as rod-like structures.

The anterior digging round chest is wider than the head, about the same length and width, the base is broad, and the anterior narrowing and tapering, and the back is densely covered with small round notches. The elytra are also densely dotted, each with an erect scale, 2-4 light red or orange-yellow colored markings on the elytra, and each elytra has an oval markings at the base and wing slope, parallel on both sides, and the rows are slightly wider than between the rows. The leg joint of the fractured leg is presented as a rod-like structure.

Freezing method. Rice if the worm is not very serious.

Rice can be included along with the container for rice.

Freeze in the refrigerator for 24 hours and remove.

Then just pick them out.

Frozen rice does not affect the taste.

Note that the freezing method does not completely freeze the rice worms to dust.

Once the room temperature is restored, it will wake up.

Therefore, after freezing, you must pick it out in time.

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 small pieces of clean gauze and wrap the peppercorns.

Place in different positions such as upper, middle, and lower in the rice box.

Then put the rice box tightly lid and it's good to go.

Sichuan pepper should be newly bought, with a strong smell.

After a while, wait for the peppercorns to fade in taste.

Just change the peppercorn gauze bag with a new one.

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.

It is then dried naturally and then used to fill the rice.

It can also effectively prevent rice insects.

3.Liquor Law.

The ethanol volatilized in liquor has the effect of killing viruses and insects.

Put a glass of white wine in the rice box, and the mouth of the cup should be higher than the rice noodles.

Allow the liquor to volatilize naturally, then close the lid of the rice box tightly.

In this way, rice insects can be effectively prevented.

But be careful, don't knock over the cup.

4.Garlic method.

Place a few cloves of garlic in different locations in the rice box.

Then close the lid of the rice box tightly, and the insect prevention effect is also very good.

5.Kelp method.

Dried kelp has a strong ability to absorb moisture.

At the same time, it also has the effect of inhibiting mold and insecticide.

Place the dried kelp with the rice according to the weight.

It is mixed at a ratio of 1:100.

Every 10 days, the god takes out the kombu and dries it until it is dry, and then puts it back.

One serving of kelp can be reused about 20 times.

This prevents mildew and insects growing in the rice.

6.Orange peel method.

Dry the peel of the oranges left over from eating the oranges.

Then put it in rice.

The taste of orange peel not only repellent insects.

It also gives the rice a fresh flavor.

7.Shade drying method.

Usually everyone likes to put raw worm rice.

Rotate in the sun for exposure.

It would be a mistake to do so.

Rice that has been exposed to the sun will lose water and affect the taste.

And the rice worms will increase unabated.

The correct thing to do is to keep the rice in a cool and ventilated place.

Bugs in the rice.

It will crawl out of the warmer rice.

Then the rice is sifted.
