1. Technology for raising flies?

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. Is it a bad thing for puppies to like to eat flies? Will it affect their health?

reason:

1. Dogs are like this when they are young. It is just their curious nature. They will not eat it when they grow up.

2. If a very young dog eats flies, it may cause diarrhea. Adult dogs are not so delicate in the stomach and intestines, so they will not have any special reaction after eating flies. But if they do this in the future, you should stop them loudly, because flies are too dirty and full of germs. Do not let dogs eat flies.

3. Puppies not only eat flies, but also lick the floor, chew wood, drink dirty water, etc., which is hard to prevent. There is no cure. If you scold your puppy too many times, the puppy will develop a sense of fear and disgust.

4. Some dogs will have pica, and you just need to stop it. Most of the time, it is caused by the lack of certain trace elements in the body. Some dogs also have pica because of worms in their stomachs. You can try deworming them.

3. What are the correct methods and precautions for breeding flies?

1. Design of fly house. Flies should be raised indoors, and it is best to build a new fly house in a semi-basement. The breeding room of the fly house does not open directly to the outside. There is a closed corridor in the house, which leads to the corridor from the back door of the studio. Black curtains should be hung on the door to prevent flies from escaping. Screens and heating equipment should be installed on the windows. The room temperature should be kept at 20-30℃, with a minimum of no less than 15℃ and a maximum of no more than 35℃.

2. Main equipment for flies. There are fly cages, food trays, egg-laying trays, and eclosion trays. The fly cage can be made into a 60-80 cm cube with thick iron wire, covered with white gauze, with an operation opening on one side. The size of the opening is suitable for placing food trays and egg trays. A sleeve is made of black cloth at the opening to prevent flies from escaping. Each food tray is equipped with 3-4 medium trays for flies to lick the feed. A small water cup is placed in each cage, and a sponge pad is placed in the cup. An egg-laying primer is placed in the egg-laying tray to induce female flies to lay eggs. The eclosion tray is used to hold the quickly eclosing fly pupae during the generation change.

3. Fly breeding and management. ① Breeding fly feed: grind the 4-day-old maggots cultured aseptically, add 60% brown sugar, 2% yeast powder and appropriate amount of water to make a paste, and add 0.1% sodium benzoate. ② Egg-laying primer: take bran and add 0.03% ammonium bicarbonate and mix well, or use chicken feces is better. ③ Stocking density: 50,000 to 80,000 flies per cubic meter of fly cage, generally 10,000 to 20,000. ④ Management method: When the breeding flies are found to be mating, they are placed in the egg-laying tray 2 days later. The egg-laying primer should be loose and evenly spread, with a thickness of 1 to 2 cm. Breeding flies lay the most eggs between 8 and 15 o'clock every day, and the egg-laying tray should be replaced in time. ⑤ Winter seed preservation: The fly pupae that have been selected and removed from the inferior can be stored in a container with appropriate temperature, humidity and loose feces, and placed indoors and covered with straw to keep warm and moist.

Key points for breeding and reproduction of flies

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 breeding temperature is significantly increased. There is no need for special heating facilities for flies. In spring, summer and autumn, the temperature in the shed can be easily maintained at 27-30℃. By rolling up and covering the straw curtains on the roof, the temperature increase and decrease measures are simple and easy, and the breeding cost is almost not increased. Even in the cold winter, the temperature in the shed can reach an average of about 20℃.

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

3. Sufficient light 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 it simple and easy to maintain light.

4. 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. Can flies be kept at home?

No. Because flies are active little insects, they move quickly and you can't control them at all. They are not human and can't be fed well. Even if you keep them in a cage, they will be depressed and lose their appetite if they stay in a closed space for a long time. Over time, they will starve to death in the closed space. Flies are little insects that love to fly, and you can't stop their yearning for freedom.

6. How to keep flies as pets?

First catch a fly, then put it in a bottle, cover it with a lid to suffocate it, then pour in glue and wait for it to dry, and a fly pet is ready.

7. What do flies eat?

When raising flies, people usually feed them some milk or animal offal. These things can be placed in places where flies gather and become good feed, allowing the flies to quickly turn into pupae.
