Maggot fly breeding supporting model and technology

Production model of breeding demonstration base

A large amount of abandoned crop straw in rural areas is used. After being crushed and treated with microbial technology, a small amount of wheat bran is added to feed maggots and mealworms; mealworm feces are used to feed pigs, and pig feces are used to feed maggots; maggot residue is used to feed earthworms, and earthworm feces and soil treated by earthworms are used to grow forage grass and special vegetables; forage grass and rotten vegetable leaves are also high-quality feed for mealworms; kudzu root, pyracantha, etc. are used as the main green plants in the farm; insect chickens (or fine-breed geese) are raised in the earthworm farm and allowed to freely feed on the unclean maggots separated from the maggot residue. The eggs produced by insect chickens are called ecological eggs and can be packaged and put on the market (market price is 2-3 yuan/piece); in addition, earthworm feces and mealworm feces can also be packaged and put on the market as flower fertilizer and feed. In this way, waste is turned into treasure, and the production of insect chickens and fine-breed pigs costs almost nothing. If conditions permit, it can also be equipped with biogas and fish and other aquaculture (turtles, soft-shelled turtles, loaches, eels, etc.)

There are two types of feed (foodstuff) for raising flies and maggots. The feed for adult flies is maggot pulp (fresh maggots are crushed) 55%, brewer's yeast 5%, sugar 40%, add water and mix evenly, stir into a paste; it can also be made of 49% whole milk powder, 49% sugar, dry yeast 2%, add water evenly, stir into a paste; or it can be made by mixing a mixture of bean curd dregs, epidermis and milk water solution. The feed (i.e. culture medium) for raising maggots can be taken locally and mixed in various ways: ① Mix a small amount of bran with poultry feed; ② Mix corn flour and a small amount of fish meal with swill; ③ Mix rice with wine lees or fine bran; ④ Add bean curd dregs to pig's scraps; ⑤ Mix peanut cakes or bean cakes with swill or cow dung; ⑥ Mix the waste from slaughtering livestock, poultry and fish with bran, bran, dregs, etc.

Among these food recipes, you can choose any one or refer to any one of them. After natural dehydration (drying in the sun or drying), maintain the humidity at 55-60%, and naturally ferment for 2-3 days to kill bacteria and parasite eggs, etc., then you can use it.

(1) How to raise fly maggots

1) Extensive breeding on flat ground: Mix fermented chicken manure, pig manure or food factory waste, spread it on the ground, and attract flies in the nature to lay eggs on it. Generally, about 150 grams of maggots can be harvested from each kilogram of material within 7 days. The key to adopting the method is to harvest the maggots in time and feed the harvested maggots to the eels in time, otherwise the large number of flies produced artificially will fly out of the eel farm and cause great harm to people. You can also put the material for cultivating maggots into a sieve, put the sieve on the container, or hang it 30 cm above the water surface of the frog pond. Using the light-avoiding and drilling properties of the maggots, the maggots drill out of the sieve and fall into the container or the bait tray, becoming live bait for the eels.

2) Housing maintenance

①Housekeeping equipment. Choose a room that is easy to keep warm and moist. The indoor temperature should be maintained at 25-30℃ and the relative humidity should be around 70%. The volume of the house should be 45 cubic meters. There should be an exhaust fan in the room to adjust the indoor air. The windows should have glass and wire mesh, and be hung with multiple black curtains to prevent flies from escaping.

② Feeding and management of house-raised flies. Put the prepared fly pupae into the house, and they will begin to eclode after 3-4 days. After eclosion, put them into the feed basin and feed them once in the morning, noon and evening every day. On the third day after eclosion, put them into the egg collection basin to let the flies lay eggs. From the fifth day, the egg laying enters the peak period, which can usually last for 15 days. According to the egg-laying law of the fly, the egg-laying time is generally between 8-14 o'clock every day. In the evening or early morning, you can arrange to collect the egg masses and replenish the feed in time.

③ Preparation of fly feed. In order to meet the needs of artificial large-scale fly breeding, the feed of fly can be solved by directly using starch saccharification and supplementing a small amount of ammonia source. The preparation method is to add 1 part of flour to 7 parts of water, mix well and cook into a paste. Add saccharification koji according to 10% of the total amount, place it in a constant temperature box at 60℃, saccharify for 8 hours until the ants are defeated, then take it out and add 1% maggot powder water and 0.001% sodium benzoate as a preservative for standby use.

④ Indoor maggot breeding. Indoor cement is used to build a maggot breeding pool with a height of 10 cm and an area of ​​1.5-3.5 square meters. The maggot breeding pool should be arranged on both sides, with a walkway in the middle for easy operation and management. Small ditches are set around the fly breeding room to prevent ants and adjust the temperature. The feed for breeding maggots mainly includes pig, chicken, cattle and horse manure. Generally, 33.3% pig manure and 66.7% chicken manure can be used, or 66.7% pig manure and 33.3% chicken manure can be used. When preparing, mix 1 part of pig manure with 2 parts of chicken manure with water, with a water content of 80%, pile it up and cover it with plastic film, and ferment it for more than 48 hours before use. Adjust the pH value to 6.5-7 before feeding. Spread 40-50 kg of feed per square meter of maggot breeding pool, evenly sprinkle 200,000 eggs, and adjust the temperature to above 25℃. After 8-12 hours, the first instar larvae will hatch. After 4-5 days, they will become golden mature larvae and can be collected and used.

⑤ Outdoor maggot breeding. Use horse manure or other animal manure to ferment and heat maggot breeding. This method does not require firewood, coal or electric heating, and is suitable for application in rural and pastoral areas. The maggot breeding shed is built in a sunny, leeward and dry place. Dig a pit with a length × width × depth of 4.6 meters × 0.6 meters × 0.8 meters. Use bamboo and film to build a shed cover with a length × width × height of 5 meters × 1.2 meters × 1.5 meters. Seal the north side with plastic film and leave a small door on the south side for easy work. Drainage pits are opened around to prevent rainwater from invading. When breeding maggots, first mix horse manure, cow manure and weeds, water them, and then fill them into the pit. Spread a layer of film on it to make it a maggot breeding trough with high sides and low in the middle. Spread 5-7 cm thick feed in the trough, and evenly spread it on the surface of the material at a rate of 200,000 eggs per square meter. At around 25°C, first-instar maggots will hatch after 8-12 hours and can be collected and used after 4-5 days.

3) Cage

Use iron bars to make several fly cages that are 60 cm long, 40 cm wide and high, and sealed with nylon window screens. Open a round hole with a diameter of 20 cm on one side of the cage, and use a cloth tube with two empty ends, with one end sewn on the edge of the hole for adding culture medium. Each cage can raise about 10,000 breeding flies.

The feed for the breeding flies is milk powder and brown sugar. For every 10,000 breeding flies, use 5 grams of milk powder and 5 grams of sugar per day, boil them with an appropriate amount of water, put them in a small basin after cooling, and put a few short straws in it for the breeding flies to lick. Use another deep small basin or bowl, put wheat bran or rice bran with a water content of 70%, and put it in the cage for the breeding flies to lay eggs.

Breeding flies lay eggs 5-6 times in their lifetime and begin to age in about 7-10 days. At this time, the fly cage can be treated with hot water to kill the aged breeding flies, and then new breeding flies can be put in.

4) Pond culture

Near the toilet, a rectangular breeding pool with a length of 100 cm, a width of 70 cm, and a depth of 50 cm is built with bricks. The inner wall and the bottom wall are smoothed with cement. Human feces, livestock and poultry feces, animal viscera, blood, etc. are put into the pool. The thickness of the material is 15-20 cm, and it is covered with a double layer of plastic cloth so that the temperature in the pool can reach 25-27℃. Then put 3-5 breeding flies in the pool and let them crawl freely in the pool to lay eggs for 12-24 hours. After 48 hours, young maggots begin to appear, and the peak of maggot production is 72-96 hours. Under normal circumstances, 1000 grams of feces can produce 370-420 grams of maggots, and viscera can produce 680-750 grams of maggots. Most of the mature maggots are on the surface of feces and should be collected in time. Otherwise, the maggot pupae will emerge as flies, which will waste feed and pollute the environment. When collecting, you can shovel the maggots on the surface into a basin of clean water, stir them with a wooden stick, let the maggots float on the water surface, and then you can use a net bag to scoop them out.

Flies are one of the four pests, but caged flies can provide poultry with 59.39% high-quality animal protein, 12.61% crude fat, and methionine, lysine, tryptophan, and various vitamins, sugars, calcium, phosphorus and other minerals that are easily absorbed by livestock and poultry. Its nutritional value is comparable to that of high-quality fish meal. Replacing fish meal with fresh or dried maggots has similar maggot protein and crude fat content, but can save 60% of the cost; fresh maggots are good feed for chickens, ducks and fish, and are rich in nutrition when taken out and fed directly; pupae are also good feed after being boiled, dried and ground into powder, and pigs also like to eat them very much; if each chicken eats 10 grams of fresh maggots a day, the egg production and egg weight can be increased by 11%, and laying hens can meet their demand for animal protein by eating 15-20 grams of fresh maggots a day. Cage houseflies, use pig manure to breed fly pupae, feed fish with pupae, and then use poultry manure to ferment and raise pigs, which can form a virtuous biological cycle.

my country has cultivated a fine variety of housefly, the Beijing housefly (the Institute of Zoology of the Chinese Academy of Sciences can provide excellent fly species). It grows fast, has a short cycle, strong reproductive capacity, and a spawning rate that is 3-5 times higher than that of ordinary flies. Each Beijing housefly can lay 1,500 eggs in its lifetime. The fly eggs hatch into young maggots after 8-12 hours, and the young maggots mature and pupate after 5-6 days. The pupae emerge again after 3-4 days. The adult flies lay eggs after 4-5 days, and a generation (i.e., a production cycle) is completed in 12-15 days. Raising flies has the advantages of low investment, labor saving, and high income. A 25-square-meter fly-raising room is divided into three layers for breeding, which can hold 60 fly cages, raise 600,000 houseflies, produce more than 60 kilograms of fresh maggots per day, and make a net profit of more than 8,000 yuan a year. On average, one kilogram of fresh maggots can be produced per square meter of breeding area, and the material consumption per kilogram of fresh maggots is only 2 cents. According to reports, raising flies to get maggots to feed poultry, eels, loaches, etc. requires an investment of more than 44 yuan, and poultry can lay more than 3,200 eggs, with an income of 500-800 yuan. Raising eels and loaches is more profitable. Moreover, the feed used to cultivate fresh maggots can still be used to fertilize the fields or as a raw material for biogas.

If there is no fly maggot farm around you, you can catch them yourself outside. I didn't find any, so I caught them myself outside. First, find a place where flies are, and then wait until night to catch them. After catching them, keep them for two or three days and you will see them mate. The next day, you can put in egg-laying objects, and they will lay eggs in them. Because their reproduction capacity is very large, you will have fly species, and you can produce large quantities in the future.

The production of fly maggots does not require any epidemic prevention measures, nor does it require modern factories. Under the conditions of civil water and electricity equipment, they can be produced on a large scale by heat preservation, manure supply, and escape prevention. Maggots do not produce toxic substances and do not pollute the environment. They can be regarded as excellent chemical engineers. According to the current level of human science and technology, it is easy to achieve factory-based breeding of fly maggots. Maggots are resistant to high-density breeding. A 50*50*50m³ fly cage can raise 10,000 to 12,000 adult flies. The domestic large-scale and factory-based production technology of fly maggots and the preparation technology of maggot biochemical series products have gradually matured. The technology is simple and easy. As long as you master some general habits, you can successfully breed them.

As for breeding flies, they are generally safe. I also sell them, and you only need to buy them once and you can breed them repeatedly in the future.

1. Egg hatching

At 20-22℃, it takes 24 hours to incubate; at 25℃, it takes 16-18 hours; at 28℃, it takes 14 hours; at 35℃, it takes 8-10 hours.

The most suitable humidity is 70%-80%.

2. Hatching of pupae

Within the suitable range, as the temperature rises, the pupal stage shortens accordingly. At 16°C, it takes 17 to 19 days; at 20°C, it takes 10 to 11 days; at 25°C, it takes 6 to 7 days; at 30°C, it takes 4 to 5 days; at 35°C, it only takes 3 to 4 days, which is the optimal development temperature.

Pay attention to the temperature during winter breeding. When the temperature is lower than 12°C, the pupae will stop developing; when the temperature is higher than 45°C, the pupae will die.

Flies become sexually mature four days after emergence and begin to mate and lay eggs. The life span of flies is up to one month. In actual production, each batch of breeding flies is promptly eliminated after 20-25 days of breeding. Under artificial conditions, as long as the temperature is suitable, flies can reproduce all year round.

There has always been a misunderstanding in the fly breeding industry that the bigger the seed, the better, so many people sieve the seed pupae and only keep the big ones for use. By chance, we found that the yield of seed flies after all the big pupae have emerged is not high. Why is this? Through continuous comparative experiments, we found that the artificial method of removing the small and keeping the big destroys the male-female ratio of the population itself, resulting in more females and fewer males. Flies are precisely "monogamous", that is, after each pair of flies mates successfully, the male fly will die (female flies only need to mate once in their lifetime). This leads to the fact that if there are many female seed flies in a population, but there are not enough males to mate with them, they will not be able to lay eggs, so the egg-laying capacity of such a population cannot be increased. The natural population is the same batch of species, with a moderate size ratio, preferably half each.
