Breeding conditions of Tenebrio molitor
Feeding equipment:
Breeding Tenebrio molitor must have a breeding room, lighting and ventilation, and heating and insulation facilities in winter.
The feeding equipment is relatively simple, and the wooden tray sieve tray is a wooden frame.
Internal requirements of feeding room. The temperature should be kept between 15℃-25℃ in winter and summer.
Feed source
The main feed is wheat bran, which can also be supplemented by wheat bran and broken straw.
Vegetables are mainly green leafy vegetables such as cabbage, radish and potato, which are used to supplement vitamins, trace elements and water demand.
Other feeds: add a small amount of glucose powder, fish meal, etc.
Scientific feeding of Tenebrio molitor
Tenebrio molitor is cultivated indoors, so it is not limited by climate and region. Its breeding technology is very simple, mainly divided into two periods: reproduction and feeding. The breeding period is divided into four stages: seed worm-pupation-cover worm, that is, adult and spawning. It sounds complicated, but it is not difficult to operate. As long as three preparations are made and three foundations are grasped, the survival rate is above 95%. The first is the choice of venue. Tenebrio molitor's life habit is that he is afraid of heat and cold, and prefers shade to light. Therefore, the farm should be spacious, well ventilated, and the indoor light should be dark to prevent direct sunlight. Such as abandoned factories, warehouses and greenhouses. If it is a small amount of farming, as long as there are vacancies.
The second thing to prepare is the equipment. The breeding tools of Tenebrio molitor are very simple. What you see is a breeding box, which specializes in breeding Tenebrio molitor larvae and can also be used as an spawning box. Its dimensions are 100 cm long, 50 cm wide and 9 cm high. There is tape paper around, mainly to prevent Tenebrio molitor from crawling out. This tool is called a mesh screen. There are two specifications, one is 4× 4 mm, which is mainly used to isolate larvae and pupae, and the other is this specification, 12× 12 mm, which is mainly used to lay eggs of Tenebrio molitor. There are two familiar utensils, dustpan and reed. What are they used for?
Having said that, it's time to talk about the venue and equipment. Tenebrio molitor is an omnivorous insect with simple feed and wide sources. Like bran, corn flour, fish meal, bean cake, etc.
In addition, feed some vegetables without pesticide residues. Tenebrio molitor is particularly interested in sweets. Pumpkins, carrots, apples and so on are all their delicacies. We made three preparations. Let's talk about three foundations, namely temperature, humidity and density.
The optimum temperature for feeding Tenebrio molitor is 23-28 degrees, and the relative humidity should be kept at 70%-90%. It should be emphasized that it is very important to grasp the density in the breeding process.
We made three preparations, grasped three foundations, and reached the key link-species selection. Mature larvae with bright colors, large size and strong posture can be used as seed insects.
Larvae should be fed less vegetables and more bran once a day, about 15 days, indicating that pupation is going on. Pupae are milky white at first, and then gradually turn yellow.
Therefore, the pupae should be separated from the larvae after 6 hours of pupation, but the action should be light when separating, and then bran should be sprinkled, because the pupae can emerge into the cover worm in about 7 days, and then eat it. Seeing this, some viewers may ask, what is this? Why do you want to put a newspaper? The main purpose of this is to separate the covering worms. Hey, look, it's a feather-covered worm. They have wings, but they can't fly, mainly by crawling. In this way, they are separated into the spawning screen. After eclosion, the cover worms were this color at first, and then gradually turned yellow and red, and began to mate with each other. When they turn this color, they will lay eggs.
Feeding more foods with high sugar content during egg period can improve its reproductive rate. A female adult will lay more than 600 eggs in her lifetime. This is the egg of Tenebrio molitor, which is about 1 mm long and has a thin shell. If the room temperature is controlled at about 28 degrees, the larvae can hatch in 7 days. Larvae grow and develop by molting, molting once every 5-7 days, and it takes 6 molts to become a commercial insect. At this time, a dustpan is used. Don't underestimate this insect skin. It can extract chitin. This kind of insect excrement is also very useful. It can be used as feed for poultry and can be sold at a good price in the market.
