How do you collect black soldier fly eggs? How many eggs does a black soldier fly have in a gram

There are many ways to collect black soldier fly eggs, and here are some common ones:

1.Natural reproduction: Black soldier flies are raised on a farm or at home to allow them to mate and lay eggs naturally. This method is relatively simple, but it takes a certain amount of time to wait for the black soldier fly to reproduce.

2.Artificial incubation method: purchase black soldier fly eggs for artificial incubation. Place the eggs on a moist paper towel, maintain some humidity, and place in a warm, dark environment. Change the paper towels once a day, and larvae can be observed after about a week.

3.Trapping method: Use the black soldier fly's favorite food as bait to attract the black soldier fly to feed. Then gather them together and capture them with a net bag or other tool.

4.Collect wild eggs: Look for wild eggs in some of the places frequented by black soldier flies. These places may include garbage dumps, places with a lot of decaying plants, etc.

It is important to note that hygiene and safety measures should be taken when collecting black soldier fly eggs to avoid harm to the environment and the human body. At the same time, make sure that the tools and containers used are non-toxic and harmless to avoid adverse effects on the black soldier fly.

It is estimated that a pair of black soldier flies can breed 300 billion maggots within six months without external interference, and can accumulate more than 750 tons of pure protein. The black soldier fly develops from eggs to adults, generally only 20 to 25 days, from eggs to adult larvae, only 4 to 5 days, short cycle, fast reproduction, high yield. The first hatched larvae milligrams, at 24 30 days, after 4 5 days of growth, the weight of maggots can reach 50 75 mg, and the total biomass increases by 8000 times.

As a lower animal, insects are about half as efficient as mammals in the energy conversion of ecosystems, but their production efficiency is 15 to 40 times that of mammals. It is unmatched by other methods of producing animal protein so far. If pigs and cattle grow at this rate after birth, they will weigh 325kg and 7500kg respectively after 5 days.

Miscellaneous and hobby of animal manure breeding black soldier fly raw materials are extensive, kitchen waste, livestock and poultry manure, rotten melon, rotten fruit and rotten vegetables, wheat bran, rice bran, distiller's grains, bean dregs and other agricultural and sideline products can be used for black soldier fly breeding, more rare is that the black soldier fly is extremely fond of food waste, animal manure, pig manure, chicken manure, duck manure and other livestock and poultry manure. A livestock farm with a black soldier fly farm is equivalent to building another insect protein feed production plant. The raw material is the manure excreted by livestock and poultry, and the product is high-quality black soldier fly protein feed.

Turning waste into treasure, turning harm into profit, The feces after breeding black soldier flies are odorless, do not attract black flies, and can be fertile and loose soil, It is a high-quality organic fertilizer for crops, and this special transformation function is beyond the reach of other feed insects.

There is no need for strict control, but the length of the egg stage is closely related to temperature27 °C is the optimal temperature for egg hatching. Incubation at 27-30 °C takes only 3 days, and in summer it can be shortened to more than 30 °CHowever, high temperatures can lead to heat death, and incubation at 7 °C below 27 °C is difficult.

Black soldier fly eggs are not laid directly in food, but look for suitable crevices in the vicinity to lay eggs, which provides convenience for the collection of black soldier fly egg masses in culture. In East China, 3-5 generations can occur in a year, and the overlap of generations is obvious. In the right environment, a generation can be completed in 35 days.

A pair of black soldier flies can lay nearly 1,000 eggs, and from eggs to mature larvae, the individual growth of water flies is nearly 4,000 times.

Exterior features:

Adult: gray-black wings, vestigial mouthparts, body length 15 20 mm, body is mainly black, female abdomen slightly red, second abdominal segment with a white translucent spot at each end. The abdomen of the male is bronze-colored.

The black soldier fly is larger. The mature larvae of black soldier flies weigh about 10 times as much as housefly maggots.

Eggs: about 1 mm in diameter, oblong, pale yellow to milky at the beginning of lay, gradually deepening in the later stages, each egg mass contains about 500 eggs.

Larvae: Black soldier fly larvae are plump with a small, yellowish-black head and a firm and resilient epidermis. The initial hatch is milky white and about long.

The larvae go through six instars, and the last instar larvae (pre-pupae) have brownish-black bodies. On average, it is about 18 mm long and 6 mm wide, and some individuals can reach up to 27 mm.

OK. Black soldier fly.

The larvae have a flattened, footless body and a pointed head. The young larvae are white, the body color deepens in the later stage, gradually turns dark brown and finally turns brownish black into the pre-pupal stage, which contains a lot of protein, and many fish like this bait.

Corn flour bait: soak the pellet feed in water for more than 20 minutes, steam the cornmeal into a nest, and the pellet feed is fully dissolved and mixed into the nest. Mix fermented bait: put cornmeal, rice flour, soybean cake flour, soybean flour.

Stir-fry together, then add the white noodles.

Stir well, add warm water and knead into a dough.

Shrimp paste bait: Corn flour is steamed into a nest, and fresh river shrimp are put in.

When using, take a small piece of the nest head and dip it in the shrimp puree and rub it. Tofu powder bait: Add cold water to the bagged tofu powder bought in the store, stir well and knead it into a dough, no other accessories need to be added, and it can be used directly.

Sponge bloodworm bait: Put the bloodworm in a bottle, put a little water at the bottom of the bottle, wash the sponge and cut it into 5-10mm squares and put it in the bottle, and the bloodworm will burrow into the sponge.

Vitamin bait: Steamed cornmeal into a nest, add brown sugar and koji wine after crushing vitamin B2 and vitamin C, take off the dough on the nest head when fishing, and dip it in an appropriate amount of accessories.

When breeding black soldier flies, it is necessary to establish breeding sites far away from water sources and residential areas, and then collect the black soldier fly eggs in the pool for hatching, and then the larvae black soldier fly produced on the same day can be put together for easy management, and the black soldier fly should be fed rotten vegetables and fruits to make it grow rapidly.

1. Breeding sites

The black soldier fly likes to eat rotten food, it will produce a large rancid smell, when breeding the black soldier fly, it is best to establish a breeding place away from residential areas and water sources, close to the garbage dump, and the reproduction rate of the black soldier fly is accelerated, and a large number of raw materials need to be transported for feeding, so the traffic around the breeding place should be more convenient.

2. Incubation method

When breeding black soldier fly, you need to establish an incubation pond in the breeding site, and then put the collected black soldier fly eggs into the pool, wait for 2-4 days, the black soldier fly will rot successfully, and it is best to gather the black soldier fly larvae hatched on the same day for feeding, easy to manage.

3. Feeding method

When raising black soldier fly larvae, it is necessary to feed them wheat bran that has fermented for a day, which is conducive to larval feeding, and it is necessary to spray humidity on the wheat bran regularly to improve the survival rate of black soldier flies, and after the black soldier fly hatches for a week, it can be fed animal feces, rotten vegetables and fruits and leftovers.

4. Feeding method

When raising black soldier flies, if the environment is too dry, or the temperature is high, it will lead to the death of black soldier flies due to lack of water, it is necessary to ensure the temperature and humidity in the breeding site, which can be placed in the environment air conditioning, etc., so that the indoor temperature is kept at about 25 degrees, and 15 cm of fine sand should be spread at the bottom of the pool.

Black soldier fly larvae are heat treated to increase the proportion of black soldier fly larvae. In this method, the black soldier fly larvae were subjected to heat treatment, so that the black soldier fly larvae underwent a stress response, so that the gas in the tail air sac was discharged.

The black soldier fly larvae are in a dead state after further heat exposure and will no longer breathe the gas back into the air sac, thus increasing the specific gravity of the black soldier fly larvae by expelling the gas in the air sac, so that the black soldier fly larvae can sink to the bottom of the water.

The initial larval feed is made of bran fermented for more than one day, and the humidity of the feed should be held in the water. After three to four days, depending on the density of the insects in the pot, it can be reared in separate boxes. After this period, the larvae can choose to be fed other feeds.

In the process of breeding water fly larvae, there needs to be a certain amount of environmental isolation to reduce the impact of odor on the environment. Therefore, black soldier flies should be farmed indoors.

The black soldier fly is a carnivorous fly that generally begins mating in the spring, and after mating, the female adult will lay eggs. If the black soldier fly does not lay eggs, it may be due to the following reasons:

Breeding environment problems: The life cycle of the black soldier fly is short, usually 20-30 days, if the breeding environment is not suitable or unclean, it will lead to the death of the black soldier fly or is not suitable for mating and egg laying.

Inadequate diet: Black soldier flies are carnivorous insects that can also cause fertility problems if they are underfed or do not meet their nutritional needs.

Unsuitable temperature: Temperature is one of the important factors affecting the egg-laying of insects, and if the temperature of the breeding environment is too high or too low, it will adversely affect the reproduction of black soldier flies.

Health problems: Black soldier flies can also cause non-spawning problems if they suffer from certain diseases or are infected with bacteria.
