Cage Flies Daily Feed Management Manual

First, understand the morphological characteristics and living habits of Musca domestica

(1) Morphological characteristics: Musca domestica is a fully metamorphic insect that has been through four stages of egg, larva, pupal and adult life.

(2) Living habits

1 Lifetime: In natural conditions, the number of births per year of housefly varies from place to place. Under artificially controlled temperature conditions, as long as the temperature is appropriate, the housefly can reproduce for an annual period.

2 Insect duration: The family fly of the housefly is shorter than other insects and develops rapidly. The developmental duration of each insect state is closely related to temperature. Within the appropriate temperature range, the development period shortens as the temperature increases. At 25 to 35°C, the generation period is only 10 to 15 days. The egg duration is less than 1 day, the larval duration is 4 to 6 days, the flood period is 5 to 7 days, and the adult's life span is 1 to 2 months.

3 Activity habits: Adults like to move outdoors during the day, inhabit more trees or indoor ceilings at night, and prefer to cluster in warm places when temperatures are low.

4 Breeding habits: Adults emerge sexually after 2 to 5 days and begin mating and spawning. Every batch of fly breeding in actual production should be eliminated after 20~25 days.

5 Feeding habits: Housefly adults like to eat liquid foods with high protein content. Water is a necessary condition for the survival of adults. Brown sugar and milk powder are the best foods for adults, and the lifespan of adults fed with milk powder, milk powder and white sugar/brown sugar can reach 50 days or more. Adding vegetables, fruits and other substances in the feed to supplement vitamins and trace elements can help increase the amount of eggs laid. Adults fed with fresh mash have an increased fecundity of 10% to 20% compared to milk powder.

Larvae like to eat corrupt organic matter, all kinds of corrupt organic matter can become its source of nutrition. The formulated artificial feed is suitable for feeding larvae after fermentation for about 6 hours.

7 Relationship with temperature and humidity: Temperature directly affects the survival, growth and life activities of Musca domestica. In actual production, it is appropriate to control the larval rearing temperature at 25~35°C, and the growth cycle below 22°C is prolonged. Above 40°C, the larvae will climb out of the medium and look for a cool and warm place. Adults stop developing below 12°C and do not produce eggs. No eggs can be laid below 15°C. The longest life is at 20-30°C, which can reach 50-60 days. Adults are most active at 30°C and rest in shade at temperatures above 30°C. If the temperature exceeds 35°C, the breeding fly is disturbed and can not lay eggs at 39°C. The fly species gradually dies at 40°C and is lethal at temperatures above 45°C. .

The growth and development of housefly eggs, larvae, and pupa require that the culture medium be moist and not flooded, and the moisture content of 50% to 60% is most appropriate. Studies have shown that the matrix moisture content has a great influence on the development of housefly eggs. When the water content is 60%, the minimum egg period is 18 hours and the hatching rate is the highest. The optimum matrix water content for larvae survival is 60%~70%; The development of the period has lower humidity requirements, with 40% to 50% humidity being more appropriate. It is difficult for adults to survive when they leave the water. In adults, the relative humidity is 50% to 80%. Adults begin to drink and feed after they have emerged for 1 hour. Generally, they die and die after 2 to 3 days of water consumption. Production is often used. Adults after spawning.

Second, cage fly technology points

(1) Determination of farming scale

The size of the farming scale is determined by the expected daily production. Taking a farm with a daily output of 100 kg of fresh fly maggots as an example, the following aspects should be considered when designing a farm:

1 Adult breeding scale: Each 10,000 head house adults are raised every day for five to six days at the peak of their eggs. They can produce 4 kg of fresh oysters. If they produce 100 kg of fresh quail, they need to feed the adults that are at the peak of egg production. 250,000 heads, considering the influence of other factors, the breeding scale of a production unit should be at least 300,000 heads. Considering the phasing out of seed flies at the same time, an update cycle takes 4 days. Therefore, two units of seed fly production scale must be prepared in order to ensure the continuous supply of egg mass needed for Nissan 100 kg fly maggots.

2 The area needed for breeding adults There are two methods for raising adult worms, cage breeding and housekeeping. A 15- to 20-cubic-meter room can be placed in two to five cubic meters of fly cages of 20 to 25, and the raised adults can meet the egg mass required for a 100-kilois fly per day.

3 The area required for feeding the fly larvae can produce 500 grams of fresh quail per square meter of cultivated area, and the daily production of 100 kilos of fresh quail requires 200 square meters of cultured area. For outdoor breeding, plane culture is adopted, and aisles, etc., occupy an area of ​​250 square meters, and are produced continuously according to five production units. The area needs to occupy 1,250 square meters. Most of the indoor production uses three-dimensional culture, and a four-story room is constructed as a production unit by four floors, and five production units are required to have a production plant of 350 square meters.

(2) Construction of aquaculture facilities

1 species of flyhouse: specifically for the breeding of adults, requiring fresh indoor air, temperature maintained at 24 ~ 30 °C, relative humidity 50% ~ 70%, 10 hours of light each day. A large glass window should be left on the south for lighting. The area of ​​each room is determined according to the farming scale, generally 20 to 40 square meters, equipped with screen doors, screen windows, exhaust fans, and heating pipes.

2 Fly cage production: It is an essential facility for raising houseflies. The fly cages usually have 50 cm square fly cages of length, width and height; they are made of coarse iron wire, steel bars or bamboo wood strips, and are then covered with plastic screens or iron screens on the side of the fly cage. A 20 cm diameter circular hole is left in the lower corner, and the mouth is sewn with a 30-cm-long cloth tube for feeding, feeding water, and picking and placing egg laying mats. When not in use, it is tightly trapped to prevent the adults from fleeing. Each fly cage should also be equipped with a feed tray, a drinking tray, and a small porcelain plate for egg production. In addition, a few pieces of nylon gauze can be hung in the cage to increase the habitat of adult fly. When used, the fly cage is fixed on the shelf like a mosquito net, and the cage is placed on a small flat plate. In order to facilitate the dismantling and easy disinfecting and cleaning, the four corners of the fly cage can be clamped or hooked on the three-dimensional culture rack.

3 breeding room: for indoor breeding. The room temperature needs to be maintained at 26~35°C and humidity 65%~70%. However, the larvae are afraid of light and do not need light. Attention should be paid to installing blackout curtains. Other indoor aquaculture facilities are determined according to the farming methods adopted, such as multi-layer breeding stands, nursery bowls, breeding boxes, breeding ponds, breeding platforms, automated production equipment and heating, control equipment, etc. These facilities are generally On both sides, people are allowed to walk in the middle to make full use of space and to facilitate operation and management.

4 Yucai plastic shed: used for warming the outer chamber. The basic structure is similar to the current anti-season vegetable greenhouse promoted. The area and quantity are determined according to the scale of feeding. Generally, 80 to 130 square meters of small sheds are commonly used as a production unit. There are two kinds of flat and three-dimensional farming. The sheds open one door to the south and the north for ventilation, air intake, and discharge. Two exhaust fans are installed above the shed, and a 1-meter-wide walkway is left in the middle and front and back of the shed.

5 fly larvae separation box: For the isolation of fly larvae when used for solid feed cultivation. The separation box is designed according to the negative phototaxis of the larvae. Its length, width and height are 50, 30, and 15 centimeters respectively. It consists of a screen, a darkroom, and a lighting part. The screen is equipped with a strong light. When detaching, the culture medium mixed with a large number of larvae is placed on a sieve plate, the light source is turned on, and the above culture medium is manually scraped off. The larvae see the light and drilled and repeat until they are separated.

(3) Preparation of aquaculture feed

Feed is the material basis for raising fly maggots. The feeds required for the breeding of fly maggots include egg-laying feeds, adult feeds, and fly maggot feeds. According to the physical shape of feeds, they are divided into solid feeds and liquid feeds.

1 Egg-laying fodder Solid fodder for attracting adults to lay eggs, also known as egg-laying (information). This type of feed is nutritionally comprehensive and can meet the nutrient requirements of adults and fly lice at the same time. And has a special smell of stench, a strong attraction to adults. When livestock manure or artificial fly maggot feed is used as an oviposition matter, spray of 0.03% ammonia water or ammonium bicarbonate aqueous solution, human urine, rotten leeks, etc. can significantly increase attracting power to adults. (Attachment: “Huoyinsu” formula: Taking 150 square meters of farmed area for one day as an example: Epimedium 5g, Yangshuo 5g, Angelica 2g, Cyperus rotundus 2g, Motherwort 3g, Dodder 3 Grams, all the above Chinese herbal medicines are all mixed, chopped or beaten into powder, when used, wrapped in gauze, and the medicine can be boiled out of the syrup. The syrup is added directly to the syrup, and it is fed for three days and stopped for three days. For three days, stop for three days.... The main ingredient and role of the ovulation hormones is the aphrodisiac of the flies, which results in more mating of the flies and allows the flies to spawn more eggs.)

2 Adult worms Like other animals, adult worms need enough egg, sugar and water to maintain their life and reproduction. Under artificial rearing conditions, artificial diets must be formulated to meet these needs. We recommend using milk powder 50% + brown sugar 50%.

3 fly maggot feed, also known as fly maggot medium, feed water content is generally controlled at 65% to 75%, sufficient water, but no clear water outflow. Commonly used agricultural and sideline products waste and Tenebrio feces 2 categories, the former with wheat bran, rice bran, bean curd residue, soy sauce residue, distiller's grains, sugar troughs and so on. To improve feed utilization, it is best to use 6-12 hours of fermentation or saccharification before use. We recommend using wheat bran 90% + fishmeal 3% + bean 6% + milk powder 1%.

(4) Matters needing attention in feeding and management

Musca domestica is an important health pest. In all aspects of feeding and management, it is necessary to do a good job of controlling breeding to prevent the breeding stock from entering the natural environment. For example, in the larval growth period, sufficient feed must be provided to prevent the larvae from crawling to find food. When the larvae are matured, the larvae must be separated and handled in time to prevent the larvae from losing their control. In the adult stage, great care must be taken. Pay attention to the closed conditions of the rearing cages and doors and windows and find loopholes in time. In the case of large-scale production, it is also necessary to strengthen the planning and continuity of production, do a good job of streamlining, organize production by unit, and inoculate one unit per day to produce one unit and update a batch of fly species.

Third, species fly breeding

After 20-25 days, the fly will spawn a large number of eggs and will be eliminated in time. The species fly should choose the eggs produced by the flies for the 6th to 10th days, and appropriately add high-nutrient feeds for centralized feeding. The flies must be large and full.

IV. Daily management schedule of fly breeding

(1) Production steps: Select site → Building aquaculture house → Fermentation feed → Adding seed fly → Cycling production.

(2) Operation steps: Incubation of earthworms (2-3 days) → Breeding of fly breeding → Collection of egg masses (starting from the third day) → Incubation (1-2 days) → Feeding (2-3 days) in divided plates → Water insulation Breeding → Separation of fly larvae → Partial seeding → Utilization of fresh alfalfa → Repetitive cycle production.

(3) Management Diary:

1 Add seed fly feed, place egg collection, and change drinking water at 6 o'clock in the morning.

2 The hatching of the aphids is reared in separate trays. Key points: Feed should be added once.

3 Record the indoor and outdoor temperature and humidity in the morning and record the incubation time of the eggs. The temperature in the fly room is too high to pay attention to ventilation and cooling.

4 At noon high temperature, observe the temperature and humidity of the fly house and pay attention to adding drinking water. A large-scale breeding day will be divided into two eggs.

After 5 pm, collection of egg collection concentrates hatching. The best time is 8-9 p.m. and can be picked up twice a day.

6 Feeding the flies on the food tray should be cleaned once every two days, including the sponge. Sponge 20-30 days to replace the new one. Otherwise, the sponge will soften and smell, and the fly will not feed on the plate.
