How are mealworms raised? Mealworm rearing techniques

1. You need to customize the wooden box, and the size can be found on the Internet.

2. Mealworms can hatch after 3-5 days at 25 o'clock, and delay hatching when the temperature decreases. After the larvae pupate, they should be separated from the larvae in time, because the pupa will not move and may be bitten by insects. After separation, the pupae should be placed in a ventilated, warm, and dry environment, and when they are more than 20, they can basically turn into black beetles after a week.

3. The trouble is to look at it every day, and if there is a chrysalis, you have to pick it out, or you will be bitten by insects or die.

Due to the limited location, details can be found at the Guosheng Aquaculture Exchange Forum.

The breeding techniques of mealworms include egg stage, larval stage, adult stage and so on.

1. Egg stage. Adults lay eggs in a wooden tray containing feed, and the wooden tray containing eggs will be replaced on the shelf, and the larvae can hatch naturally. When larval skins appear on the surface of the feed, the 1st instar has been born.

2. Larval stage.

The eggs hatch to the larvae, and the period before pupation is called the larval stage, and the larvae of all instars are the best feed for Chinese forest frogs.

3. Adult stage.

The process of pupal feathering into an adult insect is about 3-7 days to raise the skin, and the withered head, chest, feet, and wings of the ant are feathered first, and the abdomen and tail are feathered out. Because it is synchronous pupa feathering, it can be fully completed within a few days, the newly feathered adults are very immature and inactive, and the body color becomes darker after about 5 days, and the elytra become hard. Male and female adult swarms are generally in the dark when mating, mating time is longer, and the tail of the female is inserted in the sieve hole when laying eggs, and it is best not to stir at will during this period.

Feed

1. Milk, oil and egg feed.

Animal oil, milk and eggs are indispensable additives when combining and preparing plant feed, which not only increases the nutritional content of the combined feed, but also improves the palatability of the feed.

2. Plant-based feed.

Oilmeal and other feeds. If these feeds are not treated noisily, when they are released alone, the artificially bred scorpions generally refuse to eat. Therefore, before using this type of feed, it must be steamed, fried or other treatments.

Breeding techniques for mealworms: temperature, moisture, light, feeding.

1. Temperature

Mealworms are more cold-tolerant, especially the larvae are more cold-resistant, they can generally survive at more than ten degrees below zero, but half of them will enter a dormant state, if the winter breeding is not dormant, it is necessary to increase the temperature, generally at a temperature of more than 20 degrees, and the most suitable breeding temperature is about 12 to 25 degrees. It cannot tolerate too high temperatures, and in the summer it is important not to exceed 35 degrees.

2. Moisture

Breeding to maintain a certain air humidity, generally require higher humidity, not too low, require moist air, about 75%. In summer, the humidity is required to be lower, to prevent and control diseases, and in winter, dry and winter areas should increase humidity, which is conducive to growth. In the rainy spring, the humidity should be reduced, and the dryness should be replenished.

Windy autumn can replenish humidity.

3. Light

Growth requires a low-light environment, which cannot directly receive all sunlight and cannot be directly irradiated by sunlight. You can't turn on the lights. It's better to live in the dark light. You need a place that is relatively dark and not facing the sun to let in a little scattered light.

4. Feeding

Grain processing products such as breadcrumbs, corn residues, rice residues, and soybean cakes can be fed. Don't be too particular about eating, general vegetables can be fed, such as cabbage, radishes, etc., feeding does not need to be fed every day, it is generally best to feed once a few days, feed fresh and clean feed, and feed twice the weight of the insects in a box at a time.

The habits of mealworms

The young mountain insects of mealworms like to swarm, 13 on active feeding, more than 35 can still grow, more than 50 can not survive, larvae and adults have a large bite between the small killing, lack of food will also kill each other, larvae sometimes bite pupa. Therefore, the adults, pupae, larvae, and eggs of the same age should be screened out separately and placed in their respective breeding boxes.

During the growth of the larvae, the body surface color is white at first, yellowish brown after the first molt, molt once in the next 4 6 days, molt 6 times in the larval stage, and pupate when the larvae are 2 3 cm long after 50 days of age.

In the case of room temperature 20 30, after 1 week of molting into an adult, the newly emerged adult wings are white and thin, 2 days later become brown, like to be active at night, crawling faster, do not like to fly, 1 week after the emergence of the plum began to lay teasing eggs.

From the beginning of the placement and hatching of eggs, it is necessary to maintain the neatness of the entire growth and development stage, it is best to take the eggs within 1 3 days as a batch, do not put the eggs with a long time interval in a batch, lay the foundation for neat development, and at the same time continue to carry out neat screening according to the situation during the growth and development of larvae. Before word raising, first put human bran or other words in the breeding box, box and other utensils, and then put mealworm eggs or newly hatched larvae in, the larval density should be covered with utensils or no more than 3 4 cm thick, and finally lay vegetable leaves, other vegetable and fruit residues on it, so that the insects can live between the bran, biological materials and vegetable leaves, and let them eat freely.

Every week or so, sieve the insect droppings and replace them with new feed. When the larvae grow to 20-35 mm, they can be harvested and dry-fed animals. Generally, when the larvae reach 30 mm in length, the color changes from yellow-brown to light, and the amount of food decreases, which is the late stage of mature larvae, and then quickly enters the human pupation stage.

The larvae begin to feed soon after hatching, and the feces should be screened as soon as possible when the words in the production tray are basically eaten for about 5 to 10 days.

After sieving the insect droppings, new materials should be put into the table immediately. The amount of feed each time is about 20% 30% of the total weight of the worm, and the feed amount can also be adjusted in time according to the growth of mealworms during the feeding process, and the feed amount is eaten in 3 5 days. Generally, the larvae are screened for 3 to 5 days for 1 time of insect feces, and once they are put into the feed.

When sieving insect feces, attention should be paid to the type of sieve mesh, which corresponds to the size of the insect body, so as to avoid the insect body leaking out with the insect feces.

1 3rd instar larvae can not be screened to remove insect feces, 4 8 instars with 60 mesh screens, more than 10 instars can use 40 mesh screens, old mature larvae with ordinary iron screen is appropriate. When sieving insect feces, carefully observe whether the food is eaten, and then sieve the insect feces when all the feed mixed in the insect feces is eaten by the insects. Special attention should be paid to the fact that before feeding vegetable leaves and melon peels, insect feces should be screened out first, so as to avoid insect feces sticking to the vegetable leaves and melon peels, and insect feces will quickly rot and deteriorate after being wet, causing pollution.

The addition of vegetable leaves and melon peels is determined according to the specific feeding situation, and it is generally advisable to keep the food exhausted and there is no leftover.

Summary. Dear, I'm glad to answer for you: how to raise mealworm adults:

Mealworm adult breeding method: It can be fed with green plant food and a small amount of small animals in the cage, such as fleas, protozoa, etc. These substances will make the adult mealworm have good living conditions, thereby promoting their rapid growth and development.

Dear, I'm glad to answer for you: how to raise mealworm adults Mingna: mealworm adult breeding methods:

It is possible to use green plant food and a small amount of small animals in the cage, such as fleas, protozoa, etc., to feed the Joy Song and raise. These substances will make the adult mealworm have good living conditions, thereby promoting their rapid growth and development.

After the mealworm pupae emerge into an adult, it is necessary to separate it into the oviposition tray, so that the male and female adults can mate and lay eggs in the egg tray. After the adult worms are feathered in the pupation box, in addition to some sticking to the newspaper, some of them will be mixed with the pupae. The adult worm sticks to the newspaper, and we can shake it directly into the egg tray.

For adults mixed with pupae, we generally have two commonly used methods for isolation. One is leaf trapping, that is, put the leaves or banana peels that adults like to eat in the pupation box, etc., the adults will stick to the leaves to absorb water, and we can lift the leaves to shake the adults into the egg tray. There is also the method of fecal separation.

Because the adults are afraid of strong light, we can put the insect pupae mixed with the adults on the mealworm feces, and then put them in a place with strong light, high temperature weather or strong light in summer, can not be directly irradiated with strong light, as long as it is placed in a bright place, so that the adults will burrow into the feces, and the pupa will remain on the surface of the feces, and then use the fecal sieve to separate the adults from the feces.

The main points of breeding mealworm adults are as follows:

1. Rice bran, wheat bran, soil grains, green vegetables, peels, fruit pits, etc. can be used as mealworm feed, and the general mixed feed formula is wheat bran percentage.

Eight. 10. Percent of yellow corn flour.

10. 10% of peanut rice cake flour;

2. The optimal temperature range is 26 to 32 degrees Celsius, 35 degrees Celsius when the growth and development is the fastest, but long-term at this temperature is easy to get sick, more than 4 instar larvae, when the temperature is above 26 degrees Celsius, the humidity of the feed macro belt reaches about 15 percent, the temperature of the group will be more than 10 degrees Celsius higher than the surrounding environment, cooling measures should be taken, the ideal feed moisture content is 15 percent, air humidity is 70 percent;

3. Before the adult body color becomes black and brown, move it to the oviposition box of the adult reed, which is 60 cm long, 40 cm wide and 13 cm high, with barbed wire at the bottom of the wooden box, 2 to 3 mm of mesh, and the four sides of the box are inlaid with white iron sheet or glass to prevent the insect from escaping;

4. The hatching period of eggs is 7 to 10 days, so the eggs should be screened once after 7 days at the right temperature, and the feed and other debris in the box should be sieved when the eggs are screened, and then the egg paper will be moved to the incubator for incubation.
