Tenebrio molitor is relatively cold-tolerant, especially larvae, and can survive at-10 degrees. However, if the breeding does not hibernate in winter, the temperature must be raised above 20℃, and the air humidity during the breeding period should not be too low, about 75%. Because the growth of Tenebrio molitor needs a weak light environment, it cannot be irradiated with strong light. When feeding Tenebrio molitor, you can feed some bread crumbs, corn residue and other foods.

First, Tenebrio molitor breeding techniques and seedlings

Tenebrio molitor is a cold-tolerant insect, especially its larvae can survive at a temperature of MINUS ten degrees, but will enter a dormant state. If breeding does not hibernate in winter, the temperature must be raised to 20? Above c, the optimum temperature for feeding Tenebrio molitor is 12-25? Around C.

2. Keep a certain air humidity when breeding, and the humidity must be higher, not too low, about 75%. But the humidity can be lower in summer, which can prevent diseases and is conducive to growth.

3. Because Tenebrio molitor's growing environment needs weak light, it can't accept strong sunlight and live better in dark light. You can put Tenebrio molitor in a relatively dark place without sunlight, but it can transmit a little scattered light. This environment is very favorable for Tenebrio molitor.

4. When feeding Tenebrio molitor, you can feed some bread crumbs, corn residue, rice residue, bean cake and other foods. Tenebrio molitor has no special requirements for food, just ordinary vegetables, usually once every few days.

The seedlings of Tenebrio molitor can be purchased directly from the local insect breeding center or from other farmers. Pay attention to the health status of Tenebrio molitor and carefully select seedlings, because seedlings determine the survival rate of Tenebrio molitor.

Second, how to raise Tenebrio molitor

1. First choose adults or directly feed larvae, then arrange them to mate and lay eggs, and then hatch eggs. The temperature during incubation must be controlled at 25-32? C. Nymphs can hatch in about 6-8 days, and then they can be raised.

2. The mating and spawning time of Tenebrio molitor adults is generally from 10 to 2 am. They must not be disturbed during mating. Strong light and noise will frighten Tenebrio molitor and cause mating failure. The relative humidity during mating should be controlled at 65%-75%.

3. Once the adults mate, the females will put the sperm beads into the seminal vesicle. Every time an egg passes by, they will expel 1 or countless sperm, and then they will combine into a fertilized egg and be excreted.
