What do flies eat? How to raise flies?

Flies are creatures with a very sensitive sense of smell. They like many things with strong smells, and mainly like to eat insects, beetles and fruit flies.

Flies have a very sensitive sense of smell and a very diverse diet, liking all kinds of fragrant, sweet, fishy, ​​and smelly foods. They especially like all kinds of corrupt organic substances and fermented products, and can even eat phlegm, pus, blood, and sweat. The feeding characteristics of flies are that they eat, spit, and defecate at the same time, and the hairs on their bodies and the sticky hairs on their pads can carry a large number of pathogens and parasite eggs, which is the main way flies spread diseases.

What food to eat?

Flies are omnivorous insects, and most common species prefer sweet or carrion food. For example, aphid flies and parasitic flies like to visit flowers to suck nectar; fruit flies and fruit flies like to eat fruits or rotten fruits; blow flies, house flies and flesh flies prefer carrion and feces. When raising flies, they are usually fed with milk or animal offal. These things can be placed in places where flies gather and become good feed, allowing flies to quickly turn into pupae.

Breeding methods

1. Fly house design:

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 inside 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 into a paste, 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 inducer: Take bran and add 0.03% ammonium bicarbonate and mix well, or it is better to use chicken feces.

③Stocking density: 50,000 to 80,000 flies can be raised per cubic meter of fly cage, usually 10,000 to 20,000.

④ Management method: When the male and female breeding flies mate, place them in the egg-laying tray 2 days after the discovery. 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, so the egg-laying tray should be replaced in time.

⑤ Overwintering seed preservation: The fly pupae that have been removed and selected can be stored in a container with appropriate temperature, humidity and loose manure, placed indoors and covered with straw to keep warm and moist.
