Why do mealworms die in large numbers during breeding?

It should be sick, or the breeding density is too large.

Have you fed the water, is there anything wrong with the wheat bran? Vegetable leaves are not put too much. The density is not too high, the temperature is too high.

Summary. The main causes of the disease are dry air, high temperature, and low feed moisture content, which makes mealworms seriously lack water and develop the disease. In general, such symptoms are easy to occur when heating with a coal stove in winter, or when there is no rain for several days in a row (more than 39 days) in the hot summer.

The main causes of the disease are dry air, high temperature, and low feed moisture content, which makes mealworms seriously lack water and develop the disease. In general, such symptoms are easy to occur when heating with a coal stove in winter, or when there is no rain for several days in a row (more than 39 days) in the hot summer.

The disease usually occurs during the rainy season when the humidity is high and the temperature is low. Due to the humid air in the breeding place, coupled with the difficulty of screening and excessive force, the insect body is injured, coupled with poor management, the manure and feed are contaminated and the disease occurs.

According to our daily observations, the cause of blackhead disease is caused by mealworms eating their own feces. This is related to poor management or lack of knowledge of farming techniques. When the insect feces were not screened, green fodder was put in, resulting in insect feces mixed with green fodder, and mealworms ate them by mistake and became ill.

The worms I raise are mainly black and easy to stink, and one end is black, and the insects don't like to move. What kind of medicine can I use or how to manage it?

Blackheads, the indoor temperature is too high, the feed is too wet, the vegetables stick to the insect feces, and they are eaten by mistake, look at the insect feces, it may be black, then it must be. Sieve the insect feces, don't get too wet with the feed, increase indoor ventilation, and it will be fine after a while.

Generally, the humidity is not suitable, and the feces are infected with miscellaneous bacteria. Feed mold. It could also be the cause.

Causes: The disease mostly occurs in rainy seasons with high humidity and low temperatures. Due to the lack of humid air in the breeding place, the cavity and burning are difficult to sieve and the force is too large, resulting in insect injuries, coupled with poor management, manure and feed are contaminated and sick.

The symptoms are sluggish movement of diseases and insects, decreased appetite, few litters, black stools, and in severe cases, the insects become black, soft, rotten and die. The black stool from the pest drain can also contaminate other insects, and if not treated in time, it can even cause the entire box of insects to die. It is a more serious disease and the main preventive disease in summer.

Prevention and control methods: After discovering this situation, we should immediately reduce or stop feeding green vegetable feed, clean up the feces of pests and diseases in time, open doors and windows for ventilation and drain moisture, and pick out the pests and diseases that have become soft and blackened in time.

1. In the four change processes of mealworms caused by low temperatures, only the larvae of mealworms (that is, what we call mealworms) can hibernate, and the pupa, adults and eggs of mealworms cannot hibernate. During mealworm hibernation, if the temperature is below 0, mealworms will die of frostbite. 2. Lack of feed causes death of mealworms in theory below 10 into hibernation, actual breeding found that mealworms in more than 5 (when mealworms have slight activity) the same phenomenon of eating, so mealworms should be placed in the wheat bran to hibernate.

If wheat bran is missing, mealworms will bite each other and die. 3. Mealworms are eaten by rats during the hibernation of powdery insects, because people are not often in the breeding room, due to negligent management, there will be mealworms stolen by mice.

Summary. Mealworm farming is risky. First, the disease is more serious.

Five or six years ago, mealworm disease was rare. At that time, one pound of seed insects could breed and produce dozens of pounds of commercial insects. Now, the commercial insects produced by the breeding of one pound of insects are only about 6 pounds.

At present, the market price of a catty of insects is 56 yuan - 60 yuan, and the price is 4 yuan per catty. If 8 catties of adults can be bred according to the promise of some companies, the total income is only 32 yuan, which is not enough to cover the introduction price. Moreover, many companies have minimum introduction requirements, less than 100 catties, more than about 500 catties.

The risks can be imagined. Second, the cost of breeding is not low. According to the farmers, at present, it is necessary to feed about 3 catties - 4 catties of bran and about 3 catties of greens to raise 1 kg of mealworms, and the feed cost is about 2 yuan.

If you add the loss of death, equipment and labor input, etc., the cost per catty will exceed 3 yuan. According to the company's purchase price, such a cost is basically not profitable. Third, the market is not mature enough.

In previous years, mealworms were mainly used as feed for special aquaculture industries, or sold sporadically in the flower, bird, fish and insect markets. In recent years, through the efforts of some companies, the export market of the products has expanded. Some companies are willing to buy mealworms as long as they can make a profit.

But the problem is that the company does not make money if the purchase price is high, and the farmers do not make money if the purchase price is low, and it is difficult to balance the interests of both parties. At present, no effective solution has been found.

Is it profitable to raise mealworms.

Not very profitable.

It's too risky, don't get caught up in the visuals of certain platforms.

Now there are quite a lot of mealworms, and the reasons for the death of a large number of mealworms are these: 1. The temperature is too low in winter, or the high temperature of socks in summer will lead to the death of mealworms, and the temperature should be moderate. 2. Feed the mealworms wet wheat bran in summer, in the hot weather in summer, some people mix the wheat bran with water and feed the mealworms, this method will also cause a large number of mealworms to die. 3. Mealworms can not be directly blown by fans to cool down in summer, nor can they be sprinkled with water, otherwise they will die in large numbers.
