Culture technology and profit of Tenebrio Molitor

What kind of insect is the yellow powder bug? Tenebrio Molitor also has a person's name bread worm, because the nutritional value of Huangfanchong is very high, the use value is also very extensive, so there are more and more people raising Tenebrio Molitor. How much does it cost to raise yellow powder insects? How much profit will it bring?

Culture technology and profit of Tenebrio Molitor

Under the condition of mastering the technology, in our spare time, we use an area of 20 square meters to buy 100kg species of insects, 120yuan / kg, the market price of wheat bran is 0.65yuan / jin, the feed / meat ratio of feed and insect culture is 3:1, 3 jin of green vegetables, 0.15yuan / jin (average). According to the calculation of breeding-year, the average output of commercial insects per jin is 50 jin, 100kg can produce 5000 kg of commercial insects, and the production of 1 kg of commercial insects can produce 2 kg of insect dung. The current market price of insect dung is 0.5 yuan / kg.

The total cost is: wheat bran cost = 10000 jin (commercial insect) × 3 × 0.65 = 19500 yuan green vegetable cost = 10000 jin (commercial insect) × 3 × 0.15 × 4500 yuan seed cost = 100kg × 120yuan / kg = 12000 yuan.

Tool cost = customized 200wooden boxes to carpenters worth about 1000 yuan profit: production of insect dung: 5000 kg x 2 million 10000 kg; 10000 kg x 0.5 yuan / kg = 5000 yuan total income = 5000 kg × 7 yuan / kg = 35000 yuan (market price 6-8 yuan, take 7 yuan) + insect dung 5000 yuan.

Total: 40,000 yuan

Annual net income = 40, 000-12000 (seed insects)-19500 (wheat bran)-1000 yuan (wooden box)-4500 yuan (green vegetables) = 3000 yuan

Note: wheat bran can be replaced by straw bran: the ratio of straw bran to insect breeding material and meat according to 4:1 straw bran cost = 10000 jin (commercial insects) × 4 × 0.3 = 12000 yuan, the total cost will be reduced by 7500 yuan, and the annual profit will be 10500 yuan.

After the commercial insects are sold, farmers still have a large number of adults in continuous reproduction, which is a long-term benefit from the investment.

The living habits of Tenebrio Molitor

Tenebrio Molitor is in the wild once a year, overwintering as larvae, stinging around Qingming Festival the following year, and pupating in the middle of May. When the yellow powder insects are artificially raised in the greenhouse, the larvae can complete a generation in 60 days when the room temperature is kept at 30-33 degrees and the humidity is about 70%. The larvae molt for 8 times in a row and pupate.

Tenebrio Molitor is negative phototaxis, adults live in the dark corner of the surface of the grain pile; larvae lurk on the surface, pupa Eclosion day or so, the body color changes from yellow and white to reddish brown, male and female mate, and then lay eggs; the oviposition tube is long mm; the eggs are laid about 14 mm below the surface of the grain pile. The egg is oval, about 2.5 mm long, white in color, with mucus on the surface, and a variety of debris on the surface of the egg, which is difficult to find without careful examination, and is broken by gently pressing with your fingers. Adults lay 15-35 eggs a day, adults-like can lay 2000-3000 eggs, like to live in groups.

Breeding methods of Tenebrio Molitor:

1. Larvae: the larvae are raised in a wooden box, with a length of 60 cm, a width of 40 cm, a high weight of 3 cm, and a mixed feed of 3-5 times the weight of insects to release the larvae. Then cover with all kinds of vegetable leaves to maintain the appropriate temperature. After the feed is basically eaten up, sift out the insect dung and add new feed. If you need to keep seeds, it is necessary to reduce the density of larvae, generally 1 box should not exceed 250 grams. The first few groups of larval pupae should be picked out in time to avoid being bitten. In the later stage, most larvae no longer eat, so there is no need to pick pupae.

2. Pupae: sprinkle wheat bran in a larval feeding box, cover with appropriate amount of vegetable leaves, and release the pupae to be feathered.

3. Adults: the specification of the adult spawning box of Tenebrio Molitor is the same as that of the larva box, except that the bottom of the box is covered with barbed wire, the hole of the net is so that the adult cannot drill into people, and the inside of the box is inlaid with tin or glass to prevent the adult from escaping. Put a piece of paper or a piece of wood under the barbed wire, sprinkle 1 cm of mixed feed, cover with vegetable leaves to moisturize, and finally put the hatched adults in, ready to lay eggs. Pull out the board or paper at the bottom of the spawning box together with wheat bran every 7 days and put it in the human larva box for hatching.

Rearing of larvae

The larvae can eat immediately after hatching, and feed should be put in time. With the continuous peeling and growth of the larvae, the amount of compound feed should be gradually increased, and some green vegetable leaves and melon peels should be supplemented at the same time. The density of larvae of 3 weeks old was controlled at 80 000 ~ 100000 per square meter, that of 4-6 weeks old larvae was controlled at 50 000 ~ 60 000 per square meter, that of 7 ~ 9 weeks old was 30 000 ~ 40 000 per square meter, and that of 10 ~ 13 weeks old larvae was controlled at 20 000 ~ 25000 per square meter. When the larvae grow to 25-30 mm, the density is controlled at about 10,000 per square meter. The method of classification is to screen with 134 sieves of different specifications, and the larvae of the same specification are reared according to the fixed density. The insect body and feces in the culture plate should be separated regularly, and the worm body and feces should be poured into the human sieve together, and the feces should be screened and retained. The sieve was made of nylon silk. The sieve holes were 11-23 mesh in the early feeding stage and 4-6 mesh in the middle and later stage.

This paper talks about so many problems about the breeding of Tenebrio Molitor, and analyzes how much it costs and how much profit it can bring. Parents who want to raise Tenebrio Molitor should know. Breeding Tenebrio Molitor does not need a high cost, and the profit is also very good. It is a good project for breeding.
