How to cultivate Tenebrio Molitor?

The breeding technique of yellow powder insect is relatively simple. According to the needs of production, large-scale factory cultivation or small-scale family cultivation can be carried out.

(1) cultivation mode

① factory cultivation this mode of production can provide yellow powder insects as bait on a large scale, which is suitable for the breeding needs of ornamental fish. Factory farming is carried out indoors. The doors and windows of the feeding room should be fitted with screen windows to prevent the enemy from invading. Several rows of wooden or iron frames are arranged in the room, each wooden (iron) frame is divided into three or four layers, each floor is separated by 50 centimeters, and a feeding trough is placed on each floor. The size of the trough is commensurate with the wooden frame. The feeding trough can be made of iron or wood. The general specification is 2 meters long, 1 meter wide and 20 centimeters high. The inner wall of the frame is mounted with glossy paper to make it smooth and prevent the yellow powder insect from climbing out.

The ② family breeds the yellow powder insect, the scale is small, the yield is very low. Containers such as basins, wooden boxes and cartons can be put on the balcony or under the bed for breeding. Pay attention to prevent the bite of rats and flies, as well as the pecking of chickens.

(2) Culture mode

The ① box is made of wood (60 cm long, 40 cm wide and 30 cm high) and nailed with plastic window screens to prevent flies and mosquitoes from entering. In the box, there is a frame buckled around the box, with 10 mesh sieve silk as the bottom to raise the yellow powder worm; under the frame is the egg receiver, with a wooden board as the bottom. The cases are stacked with wooden frames for three-dimensional production.

② plastic buckets can be raised in any size. But the inner wall should be smooth and the rough edges should not be damaged. Put a layer of screen at the height of the barrel, cultivate Tenebrio Molitor in the net layer, and pick up the eggs in the lower layer. Cover the bucket with a window screen.

The ③ pool is made of brick and stone with an area of 1 meter. The culture pool is 30 cm high, and the inner wall is flattened with cement to prevent the yellow powder insect from climbing out and escaping.

Large area culture in ④ culture room usually adopts three-dimensional culture, that is, a multi-storey shelf is set up indoors, on which a rectangular plate (60 cm long, 40 cm wide and 15 cm high) is placed, and the Tenebrio Molitor is cultured in the plate. The larvae can be cultured at 2-3 kg per plate.

(3) feeding and management of Tenebrio Molitor can survive the winter safely above 0 ℃, and can eat more than 10 ℃. The suitable temperature for growth is 25 ℃ ~ 36 ℃, the highest is no more than 39 ℃, and the indoor air humidity is about 60%. To the south of the Yangtze River, it can be farmed all the year round. Under very dry conditions, Tenebrio Molitor (especially adults) have the habit of cannibalizing each other. The larvae and adults of Tenebrio Molitor can move day and night, but they are more active at night.

Before raising, put fine bran and other feed screened by human screen in containers such as boxes and pots, and then put the larvae of Tenebrio Molitor into the containers with a density of no more than 2 to 3 centimeters at most. Finally, cover the vegetable leaves and let the worms live between the bran and the vegetable leaves and eat freely. The proportion of worms to food is 1 kg of worms, 1 kg of wheat bran and 1 kg of vegetable leaves. Of course, the newly hatched larvae should be carefully reared, mainly throwing more corn flour and wheat bran. With the growth of individuals, increase the diversity of feed. Every week or so, replace with fresh feed and timely add wheat bran, rice bran, cake powder, corn flour, carrot slices, green vegetable leaves and other feed, you can also add appropriate amount of fish meal. The feces were cleaned every 7 days or so. The suitable growth temperature of the larva is 25 ℃ ~ 30 ℃, the suitable humidity is 80% ~ 85%, and the larva has to molt 15 times and 17 times. Grow up a little every time you molt your skin. When the larvae grow to 20 mm, they can be used to feed animals. In general, when the larvae continue to grow to 30 mm in length, 8 mm in diameter, 33 mm in length and 8.5 mm in diameter, the color changes from yellowish brown to light, and food intake decreases, which is the late stage of mature larvae and will soon enter the pupation stage. The first pupa is silvery white and gradually becomes yellowish brown. The first pupa should be picked out from the larvae in time for centralized management. The pupa period should adjust the temperature and humidity to avoid mildew.

The feeding period of Tenebrio Molitor is about 100 days. The egg hatched into larva after 3-5 days, and the larva became pupa after 8 times of molting. The pupa itself sleeps in the fodder pile and sometimes moves on its own. After 7-9 days, the pupa itself is feathered into an adult (moth). When the adult is about to be feathered, it rotates left and right from time to time, and the pupa coat can be shed into an adult in a few minutes or dozens of minutes. Adults live for 30 to 60 days. In the process of feeding, the hatching of eggs, larvae, pupae and adults should be raised separately. When the older larvae stop eating, they should be picked out and placed in another instrument so that they can pupate and feather fairies lay eggs. After 1-2 months of breeding, it entered the spawning period. At this time, the egg collection paper should be changed frequently, every 5 to 7 days, and each time the collected eggs should be put in the incubator to hatch collectively. The larvae can be hatched after 7 days and 10 days. The hatched larvae are separated and reared in a feeding box. In this way, it goes round and round and multiplies in a cycle. As long as the room temperature is kept at 15 ℃ ~ 32 ℃, it can reproduce all the year round. Each female adult can reproduce more than 3000 larvae at a time.
