Yellow mealworm breeding technology

Tenebrio nutritional value is high, artificial breeding Tenebrio simple technology, can be in indoor or outdoor plastic greenhouse culture, three-dimensional production, low investment, low cost, 1.5-2kg feed can develop 0.5-1kg Tenebrio molitor.
In recent years, Tenebrio is widely used to feed a variety of freshwater species of special aquatic animals, but also a good feed for breeding lice.
Tenebrio is an omnivorous animal, grains and bran, peel, leaves, etc. can be used as feed. Tenebrio have the same growth and development as many other insects during their lifetime, and they go through four states, the egg-larvae, the beetle-adult. The feed used was Tenebrio crawling larvae. Artificial breeding techniques are as follows.
1 The spawning box, the incubator box and the growth box are used to produce the spawning box 70X50X10 cm. The bottom is made of 1 cm thick wood strips. The iron screens can be fastened and tightened, and the surrounding area is taped to prevent escape. The box size is the same as the spawning box. The bottom does not have iron screens, but the wooden boards are directly nailed into boxes. The incubator and growth box are 80X60X10 cm and the bottom is nailed into boxes with wooden boards.
2 kinds of worms can be purchased in the market, and require mature larvae with neat specifications, active crawling, deep internodes, smooth body walls, and a body length of 25 cm or more.
3 The mature larvae are kept in the growth box, 2 kg per square meter can be placed, the thickness should not exceed 2cm, feed: wheat bran 70%, cornmeal 15%, cakes 15%. Usually appropriate to put cabbage leaves or melon skin supplement moisture. The suitable temperature for living larvae is 13-32°C. The optimum humidity is 80%-85%. The larvae can both move and feed during the day and night, but they are more active at night.
4 The management of the cockroach is initially milky white, usually 15-17mm long, floating on the feed surface. Put 2cm bran in the mash box, put the crickets picked up every day, and wait for them to become adults. Keep in a ventilated, insulated environment. Do not over-wet so that helium does not rot. Shorter pupa period, when the temperature is 10-20 °C, 15-20 days can be adultated; at 25-30 °C, 6-8 days can be adultated.
5 Management of adult adults After emergence, after the body color turns dark brown, it will be moved to a spawning box for rearing. The spawning box can be nested in the incubator and growth box. Spread a layer of feed in the spawning box, about 1 cm thick, and then put a layer of fresh leaves, adults are scattered under the leaves. These leaves are its feed, mainly to provide water and increase vitamins, with the release of eating, not excessive, so as not to excessive humidity. The leaves rotted and deteriorated.
When adults lay eggs, most of them go to the bottom between the feed and the gauze, reach out to the ovipositor, pass through the mesh holes, and feed the eggs to the feed under the net. The artificial rearing is the habit of using it to lay eggs downwards. Use a net to separate it from the eggs and eliminate adult eggs. Therefore, the feed on the web must not be too thick. Otherwise, the adult will produce eggs on the web.
Four to five days after emergence of adult mate, spawning starts. Adult mating activities do not have day and night, a mating time of several hours, multiple mating in a lifetime, spawning several times. Each time a female can lay eggs 6-15, each female can produce 30-350 eggs a lifetime, the life of adults is 3-4 months.
6 egg hatching Tenebrio fertilized egg hatching time and ambient temperature is very large, in the 25-30 °C; conditions, only 4-7 days can be hatched. To cultivate the mealworms artificially, in order to shorten the incubation period, indoor warmth should be maintained as much as possible to artificially create the optimum temperature for hatching. Under normal circumstances, the spawning box will be moved to another incubator every 7 days or so. The feed and eggs of the original incubator can be hatched until all the larvae are hatched. After the feed is eaten, the feces are removed and replaced. New feed.
7 Larval rearing When the feed during the incubation period is basically finished, the worms should be screened out. After screening, the insects are returned to the original box for feeding. The feed of the insects can be added 2-3 times, or they can be added little by little. Every day, the feces is removed once every 3-5 days. Usually feed put some green leaves, radish slices and so on. In the summer high temperature, pay attention to ventilation and cooling; in other seasons when the temperature is low, indoor additional heating equipment. Maintain a suitable living temperature of 13 to 32 °C, the optimum temperature is 25-29 °C. The temperature is less than 10°C and there is very little activity. It is safe to overwinter at temperatures above 0°C. If the temperature is lower than 0°C or higher than 35°C, there is a danger of freezing or heat death.
8 Attention Question Egg hatching, larvae, cockroaches, and adults should be kept separately and must not be polycultured. Mixed feeding is not easy to feed food according to different requirements, and adults are easy to eat eggs in the process of feeding, and larvae are easy to eat. The thickness of the rearing larvae must not exceed 2-3 cm in order to avoid fever, and the size and specifications are basically the same. Larval feeding increases with the individual's increase. The newly-produced eggs need to be sorted once every 7 days, and they are naturally hatched in boxes. When the mature larvae are larvae, they must be picked out in time and placed in the incubator. They cannot be stacked. Adults must avoid strong light, otherwise they will affect spawning. Tenebrio disease is less, but to prevent predators: such as poultry, gecko, rats and other hazards.
