1, facility construction Tenebrio molitor breeding is generally carried out indoors, and different houses are selected or built according to the scale of breeding. In the case of industrialized farming, the factory building can be divided into several rooms, and each room is equipped with a wooden frame, and each wooden frame is divided into 3-4 floors, with an interval of about 50 cm, and each floor is equipped with several larval culture trays. The size of the culture tray depends on the culture scale and management level.

Step 2 collect eggs. Larvae with large size, strong physique and strong vitality are raised separately and pupated. After the pupae emerge, the adults can be moved to the culture tray one by one and put into the culture tray. Larvae are raised on a feeding tray, and the sieve tray is placed on the tray where pupae hatch and adults lay eggs, with a layer of white paper on the bottom and then fed with compound feed.

3, temperature and humidity management Feeding Tenebrio molitor must have a feeding room, the feeding room should be ventilated and transparent, and there should be heating and insulation facilities in winter. In winter and summer, the internal temperature of the feeding house should be kept between 15℃-25℃ and the humidity should be 60%-70%. Thermometers and hygrometers should be set indoors. A thermometer should also be inserted in the center of the worm tray to measure the temperature.

4. Feed feed mainly uses wheat and vegetables as feed, and vegetables mainly include Chinese cabbage, radish and cabbage. Wheat drums can be replaced by a small amount of coarse corn flour and rice bran. Generally, 1 kg Tenebrio molitor can be raised for every 3 kg of wheat bran and 6 kg of vegetables.

5. Daily management matters

(1) Dead pupae and adults should be removed in time to avoid rot and attract germs, and the molting and feces of larvae should be screened out in time to facilitate timely replacement.

(2) The paper for catching eggs should be replaced in time, and the paper for catching eggs should be put in a different box for hatching each time to avoid different sizes of larvae.

(3) Mature larvae are about to pupate when they turn white, so the pupae should be picked out in time to prevent the larvae from killing them. Because both adults and larvae have the habit of killing each other, high-density feed is not suitable.
