CATDOLL : CATDOLL: What are the methods of raising flies? (What are the methods of raising flies? Picture)

1. Shandong fly breeding technology?

The use of cage nets to raise flies in ordinary houses has been a commonly used technology in China in recent years.

This technology requires heating facilities to be installed in the room. Otherwise, when the indoor temperature in autumn, winter and spring does not reach 27 degrees Celsius, the reproduction capacity of flies will be seriously reduced. When the room heating temperature is low, especially in the north, flies have to be pupated to survive the winter, which causes the fly breeding to be interrupted and the economic benefits to decline sharply.

Breeding flies in plastic greenhouses has successfully solved this problem. It allows flies to be produced continuously all year round, increasing breeding efficiency several times, making it a very promising technology.

Flies have the following requirements in terms of temperature, humidity and light:

The most suitable temperature for flies is 27℃～30℃. At 8～12℃, flies can move, but cannot mate or stand on food. They can only land on the ceiling and walls and do not like to move. At -5℃, they die in 3～5 days. Fly larvae require higher temperatures than adults. The most suitable temperature for their fastest development is 35℃. They stop moving at -1～2℃ and die at -5～6℃. When the temperature is too high (45～55℃), their growth rate is reduced by half compared with normal temperature.

Fly larvae require a food temperature of 30-35℃. In terms of humidity, adult flies require an indoor humidity of 55%-60%. When the humidity is too high, the legs and body of flies are easily wet and hinder their activities. The humidity required during the growth period of larvae is 65%-70%. Flies like to move around in bright places. The brighter the light, the more active they are. Artificially bred flies should be equipped with lighting in the room, with more than 10 hours of light per day.

The use of plastic greenhouses to raise flies can easily meet these characteristic requirements of flies during reproduction, and its advantages are as follows:

1. The feeding temperature is significantly increased

Without the need for special heating facilities, the temperature in the shed can be easily maintained at 27-30℃ in spring, summer and autumn. By rolling up and covering the straw curtains on the roof, the temperature increase and decrease measures are simple and easy, and almost no increase in breeding costs. Even in the cold winter, the temperature in the shed can reach an average of about 20℃.

2. Humidity is stable and easy to maintain

To raise flies in ordinary houses, you need to constantly sprinkle water on the ground to maintain a certain humidity. However, in a plastic greenhouse, because of its good airtightness and the fact that the ground is not hardened with cement, there is no need to sprinkle water or specially adjust the humidity.

3. Adequate lighting

In the plastic greenhouse, lift the straw curtain on the roof, and the sunlight filtered by the plastic film will illuminate the entire greenhouse, making lighting maintenance simple and easy.

The area of ​​the greenhouse can be determined according to the size of the breeding. There are two ways to raise flies in a plastic greenhouse: one is to set up a three-dimensional gauze net in the greenhouse and raise flies in the net; the other is to raise flies in the greenhouse, stack a certain amount of straw and straw rope in the greenhouse, and regard each greenhouse as a cage. This method requires more investment than the previous method, occupies a large area, and has a low breeding density.

The breeding method of setting up gauze in the greenhouse generally builds a plastic greenhouse with a length of 20 meters, a width of 4 meters, a low wall height of 2 meters, and a high wall height of 3 meters, with 3 layers of gauze.

How to raise adult flies:

Breeding cage: The cage frame is 50×50×50 cm in size, with a gauze of the same size tied on it. In the center of one end of the gauze is a cloth sleeve with a diameter of about 20 cm and a length of 33 cm, which is used to take flies out and change food.

A feeding dish (7-9 cm in diameter) is filled with sugar for adult flies to eat, or a piece of water-soaked foam plastic is placed inside it to provide a water source for adult flies, which can also be used to attract eggs.

8,000 to 10,000 adult flies are raised in each cage. Whether it is newly collected adult flies or adult flies that have just emerged, sugar and water must be provided in time to prevent them from starving to death. Adult flies lay eggs 3 to 5 times in their lifetime, up to 10 times, and each time they lay 100 to 150 to 300 eggs.

Larvae rearing method: First place the feed in the rearing box with a thickness of no more than 4 cm. Then use a worm shovel to slowly place the trapped fly eggs (one-day-old larvae) on the feed in the rearing box. The young maggots will slowly disperse and drill into the feed. When the larvae eat the feed, they generally eat from top to bottom. If the humidity or temperature in the box is high, or the feed is insufficient, or the insect density is too high, the young maggots will crawl out. The breeder should check at any time and take timely measures such as adding feed or lowering the temperature or humidity.

2. How to keep flies warm in winter?

In order to produce maggots normally in winter and ensure that there is fresh bait to feed our economic animals every day, flies will not lay eggs once the temperature is below 20 degrees Celsius. At this time, we must find ways to take insulation and heating measures, strengthen indoor insulation management, check the indoor temperature frequently, and raise the temperature in time if the temperature is lowered. If coal is used as a heating furnace, coal should be added late at night, and the amount should be enough to ensure that the temperature is above 20 degrees Celsius throughout the night. The requirement is: the temperature difference between day and night should not exceed 5 degrees Celsius.

3. Fly breeding technology?

The growth process of flies is divided into four stages: eggs, maggots (larvae), pupae, and flies (adults). The following mainly discusses the first three stages.

1. Eggs: After the flies hatch, they will be raised by humans for 3 to 5 days before mating, reproduction and egg laying. The egg-laying period is 5-10 days. The egg-laying feed must be fermented in advance, and the moisture content and ratio must be controlled. After the fly eggs are extracted, they are immediately placed in the hatching room for hatching. The temperature, humidity and ventilation time of the hatching room are adjusted according to the season. The hatching time of the fly eggs is generally 8-24 hours. After hatching, they can be prepared for breeding in the fly maggot pool.

2. Maggots (larvae): seeding is distributed according to the density of hatched larvae (Note: if the larval density is too small, the larvae will grow large, but the yield will be too low. If the density is too large, the nutrition will be insufficient and the maggots will become smaller). Requirements for the ratio of the base material for seeding in the maggot pool (the moisture content of fresh pig manure should not be too much or too little. If the base material is not properly controlled, it will seriously affect the development and growth of the larvae and even cause death). Maggots mature in about 4 days in summer and about 6-8 days in winter. According to the current maggot breeding technology, maggots can be bred all year round.

3. Pupa: When the fly maggots mature, they crawl into a drier environment, shrinking back and forth to become pupae. Their body color changes from light to dark, and finally to chestnut brown. It takes 2-4 days for the maggots to become pupae. The large maggot pupae can be kept as seeds to ensure the reproduction rate of the next generation and extend the egg-laying period, so as to achieve a cycle of breeding.

5. 8 methods of breeding maggots?

1. Maggot breeding - chicken manure breeding method

1. Dry and mash the chicken manure, mix it with a small amount of rice bran and wheat bran, and then mix it with mud to make a pile, and cover it with straw or weeds. Make the top of the pile concave, pour sewage 1 to 2 times a day, and a large number of small maggots will appear in about half a month, and then drive the chickens to find food. After the maggots are eaten, pile the manure, and after a few days, the maggots can be fed to the chickens again. In this cycle, each pile can produce maggots many times.

2. Mix fermented chicken manure with beer dregs or soy sauce dregs in a ratio of 4:1 and spread it evenly on the floor with a thickness not exceeding 17 cm and a water content of about 70%. Put some rotten vegetable leaves, smelly fish and shrimp on it to attract flies to lay eggs. After a few days, many maggots will be born, and then the chickens will be driven to peck at them.

2. Maggot breeding - cow dung breeding method

1. Dry and crush the cow dung, mix it with a small amount of rice bran and bran, mix it with mud, and pile it into a round pile with a diameter of 100-170 cm and a height of 100 cm. Cover it with straw mats or weeds, and water it 2-3 times a day to keep it in a semi-dry and semi-wet state. After about 15 days, a large number of maggots will be born. Open the straw mats and drive chickens to eat. After the maggots are eaten, pile up the cow dung again, and many maggots will be born again after 2-3 days.

2. Dry the cow dung until it is half dry, add a small amount of weeds, chicken feathers, and distiller's grains, stir it into a paste with warm water, pile it into a rectangular shape, paste a layer of thin mud on the surface of the pile, and cover the top of the pile with a layer of straw or wheat straw. After about 15 days, a large number of maggots will be born in the pile. Drive the chickens to peck at them, and after the maggots have eaten them, add more raw materials and continue to breed maggots to feed the chickens.

3. Maggot breeding - human feces breeding method

Dig a 17-cm deep earth pit, spread a layer of straw on the bottom, pour human feces on the straw, cover the feces with straw mats, and after 7 days, maggots will be bred. Open the straw mats and drive chickens to eat. After the maggots are eaten, put human feces in the pit again, cover with straw mats, and continue to breed maggots and feed chickens.

4. Maggot breeding - rice straw breeding method

Cut the straw into 3-7 cm long pieces, add water and boil for 1-2 hours, bury them in a 100 cm long, 67 cm wide and 33 cm deep pit, cover with 6-7 cm sludge, and then seal with thin mud. Water every day to keep it moist, and maggots will be born in 8-10 days. Dig up the grass holes and drive the chickens to forage freely. The maggots can feed 10 chicks for 2-3 days. This method can determine the number of pits to be dug according to the number of chickens. After the maggots are eaten, cover with sludge and continue to breed.

5. Maggot breeding - leaf and fresh grass breeding method

This method uses 80% fresh grass or leaves and 20% rice bran, mix them evenly, add a small amount of water and cook them, then pour them into a clay jar or pond. After 5 to 7 days, a large number of maggots will be bred, which will drive the chickens to peck at them.

6. Maggot breeding - pine needle breeding method

Dig a 70-100 cm deep, unlimited length and width pit, put in 30-50 cm thick pine needles, pour in an appropriate amount of rice washing water, and then cover with 30 cm thick soil. After 7 days, a large number of maggots will be born. Dig up the soil to drive the chickens to eat. After the maggots are eaten, fill with pine needles and continue to breed maggots to feed the chickens.

7. Maggot breeding - bean cake breeding method

Mix a small amount of bean cake with tofu dregs and ferment them, then mix them with chaff and leaves, put them in a 7-10 cm deep pit, cover them with a layer of mud, and then cover it tightly with grass. After 6-7 days, many maggots will be born, and then the chickens will be driven to peck at the maggots.

8. Maggot breeding - tofu dregs breeding method

Place 1-1.5 kg of tofu dregs directly in a water tank, add a bucket of rice washing water or rice water, cover the tank after 1-2 days, and maggots will be bred after 5-7 days. Take out the maggots, clean them and feed them to chickens. After the maggots have eaten them, add some more tofu dregs to continue breeding. If 6 tanks are used to breed maggots in turn, 50-60 chicks can eat them.

9. Maggot breeding - soybean and peanut cake breeding method

Mix 0.6 kg of soybeans, 0.5 kg of peanut cakes, and 1-1.5 kg of pig blood evenly, seal them in a water tank, and maggots will begin to appear after 4-5 days at about 25°C. The number of maggots increases day by day, and can be eaten by 50 broilers. The maggots are large, rich in protein and vitamins, rich in nutrition, easy to digest and absorb by chickens, and the effect is close to that of high-quality fish meal. According to experiments, the weight of broilers can reach about 2 kg within 50 days.

10. Maggot breeding - lees and bran breeding method

Choose a moist place, dig a 30cm deep earth pit according to the amount of feed, spread a layer of broken straw on the bottom of the pit, then add 5-6cm long wheat straw, corn straw and weeds, then add bran and distiller's grains, water and mix well, place in the tank, and finally cover it tightly with soil. Under conditions above 30℃, it can be fed to chickens in about 15 days.

Among these 10 maggot breeding methods, it is generally advisable to maintain a semi-dry and semi-wet state during maggot breeding, but it should not be too dry or too wet, so as not to affect the breeding effect.

6. What’s the best way to kill flies?

There are two best ways to kill flies:

1. Environmental improvement means controlling and dealing with the breeding grounds of flies.

2. Kill flies with drugs or a fly swatter.

We need to take preventive measures against flies, specifically home prevention and food prevention.

Prevention at home:

1. Put domestic garbage in plastic bags and clear them daily. Do not let them stay in one place for a long time to prevent flies from coming into contact and laying eggs.

2. Trash bins (boxes, carts) must be covered and removed in a timely manner.

3. Timely eliminate garbage and sanitary dead corners in front of and behind houses, inside and outside units.

4. Restaurants, stalls and places where food is available should have fly prevention and fly killing facilities.

5. Residents in urban areas are prohibited from raising poultry and livestock.

6. Do not use the internal organs and bones of chickens, ducks, and fish as fertilizers.

7. Hotels, restaurants and bars must have complete fly prevention and control facilities, and garbage must be sealed and removed in a timely manner.

8. You can use natural enemies for prevention and control, such as spiders, geckos, etc.

Food prevention method:

Vinegar fly repellent method - spray some pure vinegar indoors and flies will stay away.

Orange peel fly repellent method - light dry orange peels indoors to repel flies and eliminate indoor odors.

Onion fly repellent method - put more chopped onions, shallots, garlic, etc. in the kitchen. These foods have strong spicy and irritating smells that can repel flies.

Tomato fly repellent method - Placing a pot of tomatoes indoors can repel flies.

The method of using leftover tea to repel flies - dry the leftover tea leaves and burn them near the toilet or sewer. It can not only repel mosquitoes and flies, but also remove odors.
