Artificial breeding of sterile fly maggots
With the rapid development of the aquaculture industry, the demand for high-protein feeds is increasing throughout the country. Artificial breeding of sterile fly maggots has opened up a new path for the development and utilization of animal high protein feeds. One cubic meter, more than a box of sterile fly species 12,000, only 20 grams of powdered milk a day, the eggs produced every day in 4 kg of wheat aquaculture, raised to the fourth day can take insect feeding frogs, wood frogs, Tanggu, seven-star fish, cockroach, cockroach, etc., spawn every day, with daily insects, 1 cubic meter of 12,000 fly species can produce more than 2 kilograms per day, the output of the first to 5 days of normal spawning insects Up to 5 to 6 kilograms a day, the equipment is simple, only 6 meters nets to make a cage, more than a dozen plates can be mass production, very easy to raise, a seed can be left to expand. First, housefly habits Housefly at room temperature 20 °C ~ 30 °C, relative humidity 60% ~ 80%, kidneys developed after five days, from soft to hard, from beige, light brown, dark brown to black, and finally into The fly breaks its shell from the front of the cocoon. The flies that just climbed out will only climb and fly. After an hour, they will spread their wings to eat and drink. Adult flies lively during the day, do not move at night, sexual maturity after three days, male and female began to lay eggs spawning, 1-8 days of age for the peak period of egg laying, to 25 days of age basically lose the ability to lay eggs. The fly eggs hatch from half a day to one day, and they are raised in pigs and chicken droppings. One generation of flies, about 28 days. The temperature and bright material nutrients have a great influence on the growth and development of earthworms. In general, the room temperature is in the range of 20 to 30°C. The higher the temperature and nutrients, the faster the earthworms grow and develop, and the bigger the earthworms become. Second, the breeding of seed flies species breeding flies should be placed. The size of the species of flyhouses, as required, can also be retrofitted with existing homes. Glass and screens are installed on doors and windows to facilitate temperature control and fans are installed on the walls to regulate air. The room should be equipped with heating equipment, so that the winter temperature to maintain 20 °C ~ 32 °C, the relative humidity in the room to maintain 60% to 70%. A black cloth curtain was placed on the channel to prevent flies from fleeing. There are breeding frames in the room, divided into upper, middle and lower levels. The frame is made of iron or wood. The fly cages made of nylon gauze were placed on each shelf. The cages were 100 cm long and 80 cm high. They were kept in cages. 12,000 fly species were kept in each cage. Each cage was covered with cloth sleeves so that Feeding, adding water and picking eggs, 12,000 adult flies feeding 20g of powdered milk every day, feed in a material basin with a gauze mat surface, let adult flies stand on the gauze and feed and water once a day. The basin was placed in gauze, and wet wheat skin was placed in the spawning dish for spawning. Each day, the eggs were harvested spawningly and sent to the mortuary for breeding. The spawning of species flies is most frequent from 8 o'clock to 3 o'clock per day, and the oviposition time should be appropriate. Each batch of fly breeding 15 to 20 days will be eliminated. Kill it with hot water or steam, dry the mill for livestock feed, and replace it with a batch. III. Cultivation of fly maggots The breeding of fly maggots can be equiped with brickwork with an edge height of 20 cm, an area of ​​1-3 m2, or a plastic tray for raising quails. A plastic disc with a diameter of 50 cm is fertile.蛆 1.5 kg only need 3 kg of wheat husk, raise 3 to 4 days can be collected and utilized, the source of raising ramming material is wider, the cost of different ramming materials is high and low, can be reasonable choice. Malpigh nutrition is slightly higher in all classes of the human body and is generally used to breed fly species. Low-cost wine troughs and bean dregs can be used as commercial loquat beads. If using wheat husk as sieving material, generally 1 kg of wheat husk can produce 0.5 kg fly larvae. When used, it needs to add water and mix well. The dry humidity should be squeezed out by hand and the water should be touched. If it is touched and scattered, it is suitable if there is wine trough, bean dregs, etc. Wet materials can be cultured without adding water. Specific breeding habits: The fly eggs and wheat skin material into the plate, add wine, bean dregs or wheat flour and other dipping material, can be mixed slightly. Note that fly eggs should not be exposed on the surface of the dip material to avoid loss of water and loss of omission. The thickness of the dipping material is not higher than 40 in the dipping material fermentation temperature, not less than 20 as the standard, generally 5 to 10 cm, the summer temperature is too high to dilute the material to be more appropriate, on the contrary, the low temperature in winter can be appropriately increased. Thicker, if the use of human and animal excrement to kill bacteria and parasites after use, the ratio of its material and wolfberry, chicken manure as an example 3.5 to 4 kg 0.5 kg of fresh oysters. Regardless of the kind of raw materials used to raise oysters, the dry humidity of the mash should be controlled at 60% to 65%. 4. Collection of fly maggots Using the characteristics of the fly pods that are sensitive to light, collect them and use the urine manure in the feed huts in the larvae to continuously promote the animals. The fly maggots will drill down and remove the surface manure. This method is repeated. Many times, the last remaining amount of manure and a large number of fly larvae, the isolated fly maggots can be directly used to feed livestock and poultry, but also can be baked at 200 °C ~ 250 °C conditions for 15 to 20 minutes, drying processing into Tantalum powder is stored for future use. V. Breeding of fly species: In the production of fly maggots, some of them are also used as a source of new fly species. There are two ways to eliminate maggots: one is to let quail in the material and the water is washed out. Feed, that is, the fly maggots; the other is when the quail in the dip material cultured in about 5 to 6 days become yellow mature, the pupa will be taken out into the pot with dried wheat, promote phlegm, and then use the sieve Separation of wheat husks yields pods The size of the cockroach is required to reach 50 cocks per gram.
