Can cabbage worms be raised?What should I do if the cabbage worm does not move?

The cabbage worm can be raised, as long as it is replaced with fresh cabbage leaves every day, preferably young leaves, and then prepare the tools for raising cabbage worms. However, it is still not recommended to raise cabbage worms, because it is very harmful to crops, so it is not recommended to raise cabbage worms!

The damage caused by cabbage worms to agriculture is as follows:

1. The larvae bite the host leaves, only eat the mesophyll before the 2nd instar, leaving a transparent epidermis, and after the 3rd instar, the leaves are eaten up by the holes or missing carvings, and the serious leaves are eaten up, leaving only rough leaf veins and petioles, resulting in runoff, which is easy to cause the epidemic of cabbage soft rot. In the seedling stage, when the damage is severe, the entire plant dies while light affects the pericardium. The larvae can also burrow into cabbage leaves, not only in the leaf bulbs to eat the heart of the vegetable, but the feces also pollute the heart of the vegetable, making the vegetable of poor quality, and causing rot, reducing the yield and quality of the vegetable.

Spring and autumn are the most harmful seasons of the year.

2. The larvae spray mulberry leaves into curls or folds and hide in them to feed on the young leaves. As a result, the mulberry leaves have only skin and filaments, and the flesh is eaten up, like a transparent film, grayish-brown in color. The harsh conditions will directly cause the entire mulberry leaves to wither and yellow, and silkworms cannot be raised.

On the other hand, the excrement of cabbage insects will cause pollution to mulberry leaves, thus affecting the quality of mulberry leaves, and if they are accidentally fed to silkworms, it will cause white beever and affect the harvest of silkworm farmers.

Hello!Cabbage worms can not only be raised, but also edible, with high nutritional value, containing a lot of protein and vitamins.

Then you can get rid of the worms directly, and it's better not to play with the medicine when you eat it yourself, it's healthier.

Life evolved survival skills, play dead, and leave it alone for a while. . .

If the cabbage worm does not move, it means that the cabbage worm may be hibernating or the season of pumping lice has arrived, so the cabbage worm has its own life rules.

The green vegetables that are raised are not moving, what should I do?From the fact that he has a lifespan, he does not move, which proves that his lifespan has arrived.

The Tao Te Ching is one of the greatest masterpieces in Chinese history, and has had a profound impact on traditional philosophy, science, politics, religion, etc. [3] According to UNESCO statistics, the Tao Te Ching is the most widely translated and published cultural masterpiece in foreign languages other than the Bible.

The body of the cabbage butterfly is divided into three parts: the head, thorax and abdomen, with 3 pairs of feet, 2 pairs of wings, an exoskeleton, feet and antennae segmented, so the cabbage worm belongs to the insect class in the arthropod animal.

The cabbage butterfly is the larva of the cabbage butterfly, and the reproductive mode of the cabbage butterfly is to lay eggs after mating, and the eggs hatch into larvae - cabbage worms, which first become pupae when they grow up, and then the pupa feathers into cabbage butterflies. With the different living environment, its color is deep and light, the markings are large and small, usually growing at high temperatures, the black spots on the wing surface are dark and the yellow scales in the wings are bright. On the other hand, individuals who develop and grow under low temperature conditions have few black scales and small spots, or disappear completely.

Chinese cabbage fertilization method and fertilizer amount:

1. Planting Chinese cabbage should have enough organic fertilizer as base fertilizer, generally Zhuxiang per mu (square meter) to apply thorough decomposition and harmless treatment to complete and up to the standard ny 525-2012 of high-quality organic fertilizer 4 5 tons (powdered is easier to use, cheaper, you can also teach you to make yourself, the cost per ton is about 200 yuan), the use of ditch or hole application, the fertilizer is applied into the soil.

2. The top dressing of Chinese cabbage should be based on the principle of "light in front and heavy in the back", and it is the focus of top dressing from the rosette stage to the early stage of the heart. When 8 10 true leaves of Chinese cabbage are applied, 10 15 kg of 45% compound fertilizer is applied per mu, and 4 5 kg of urea per mu is chased at the rosette stage to the early stage of balling, and 5 kg of potassium fertilizer is applied at this time, which can significantly improve the yield and increase the net vegetable rate.

3. In the northern region, Chinese cabbage is prone to dry heartburn due to calcium deficiency, and calcium nitrate solution can be sprayed at the early stage of balling. For many light acidic soils in the south, Chinese cabbage is prone to boron deficiency, and foliar spraying can be carried out with borax or boric acid solution, which has a good control effect.

4. In case of non-insect pest-generated leaf curl virus, use our 30% suspension (agent) fertilizer series in the green exhibition as the main drug, hit three times, with an interval of seven days, if it is mosaic virus or yellowing virus, you can use our series of detoxification leaf exhibition to spray it like this. At the same time, ordinary foliar fertilizer does not need to be used. Cabbage worms are sprayed directly with Bacillus thuringiensis with high bacterial content.

The soil methods that can be used for green cabbage insects are: plant ash, insect treatment, common substances, and various intervals.

1. Grass and wood ash:

This substance is a very useful substance for crops, not only to provide potassium fertilizer, but also to control pests. It can be soaked in water, or it can be treated by sprinkling it directly, and there is a high probability that the pests can be disposed of.

What needs to be paid attention to is the timing of use, the time when the pest is active is at night, so it can be controlled at night, and the control can be carried out at night when the green insect activity is more frequent.

2. Treat insects with insects

If you find this kind of green worm on the leaves, you can catch a few by hand and put them in a jar and mash them. Add water and soak it in water, which has basically rotted and deteriorated, and spraying this water on the leaves can play a good role in repelling.

3. Common substances:

Substances such as laundry detergent can be mixed and diluted in a certain proportion, which is very lethal to insects. Spraying it on the leaves by spraying it is a good way to remove insect pests, and there is a 90% success rate, so it is recommended to try it.

4. Diverse intervals:

You can use the special smell of peppers and other plants to repel insects, and only when you grow them are you growing them at different intervals. This method can effectively help get rid of the green worms that are originally on the leaves, and can improve the overall quality of the vegetables.

Popular science of cabbage insects:

Cabbage butterfly, also known as cabbage white butterfly, larvae, also known as cabbage worm, is the most widespread distribution in China, the most serious harm, often become a pest. There are as many as 35 species of host plants in 9 families, and they are fond of cruciferous plants, especially cabbage, cauliflower, cabbage, and radish with thick leaves.

The cabbage insect is most afraid of its natural enemies: birds, praying mantises, Chinese leaping spiders, toons, Chinese microspiny blind bugs, hunting bugs, turtle ladybugs, heterochromatic ladybugs, butterfly pupae golden wasps, red-eyed bees and other natural enemies.

Precautions: Insecticides such as chlorpyramide and cypermethrin are generally used for control. Among them, chlorpyramide has a slow effect and needs to be sprayed mainly for prevention or in advance. In order to reduce pollution, plant-derived pesticides such as pyrethrin EC, pyrethrin EC, and azadirachtin EC can be used for control.

Because cruciferous vegetables eat leaves, high-efficiency and high-toxicity insecticides cannot be used, otherwise it is easy to cause food poisoning.

The prevention and control of cabbage insects is mainly prevention, and it is necessary to produce in the adult occurrence period, if the planting area is small, it is generally controlled by manual capture, which can avoid pesticide residues.
