1. Is it easy to raise blowflies?

Answer: Easy to raise. First, low risk and high benefit.

Fly farming is not like other farming industries. There is no epidemic disease in fly farming, and there is no need to spend a lot of effort on disease prevention. It is not like agricultural projects that are affected by typhoons and rainstorms, resulting in reduced production or bankruptcy.

Small investment and high efficiency.

Second, the equipment is simple and easy to operate.

The production equipment is simple and economical. As long as it can be windproof and heat-insulated, it can also be used to renovate old houses.

Third, the breeding technology is mature and easy to manage.

Fly farming is suitable for high-density breeding and can be factory-produced. One person can raise millions to tens of millions of breeding flies, and the workload is not large.

Fourth, production can be carried out every day of the year.

With a little insulation, production can be carried out all year round without affecting the output.

Fifth, the source of feed is vast, easy to obtain and cheap.

The feed required by flies and maggots is domestic waste and livestock waste.

2. Cost comparison between black soldier flies and maggots?

Feed sources

Black soldier flies - almost all animal feces within 10, kitchen waste, slaughterhouse scraps, wheat bran, fish and shrimp and scraps, fruit and steamed vegetable scraps, food processing scraps, a variety of fresh grass, etc., the feed sources are very wide.

Fly maggot breeding - fresh pig manure, chicken manure, slaughterhouse scraps, wheat bran, fish, shrimp and scraps within 3 days, etc.

Yield Comparison

Black soldier flies - each cubic meter of feed produces about 250 kg of black soldier flies

Fly maggot farming - about 150 kg of maggots per cubic meter

Feeding influence

Black soldier flies - easy to raise, no impact on the environment

Fly maggot farming - easy to raise, but will have an impact on the environment

Cycle time and cost

Black soldier fly - one cycle is about 20 days, 0.3-1 yuan/kg

Fly maggot farming - 7-10 days per cycle, 0.5-1.5 yuan/kg

3. How many flies can be raised in one square meter? How many maggots will be produced?

Fly farming, 80,000 to 100,000 flies per cubic meter, and 10,000 flies can produce 1 to 2 kilograms of fresh maggots per day

4. 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.

5. 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.

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.

6. What are the economic benefits of gadfly farming?

It reproduces quickly, has a wide range of food, is easy to manage, has low breeding costs, and can bring good economic benefits to breeders. The breeding prospects are promising. The price varies depending on the type and origin of the black gadfly. Currently, it is basically 10-20 yuan per catty.

It only takes 45 days for black gadflies to reproduce and go on the market. The breeding base can produce small flies like snowballs. At present, the purchase price of feed processing plants is generally 6,000 yuan per ton, which is very profitable.
