Tenebrio molitor is the bread worm we often say. It is a mollusk reptile. It is present in many places in China. Tenebrio molitor has high breeding value, and there are many people breeding it. However, many people did not know much about its specific breeding methods and breeding techniques before breeding.

How to raise yellow mealworm
1. Temperature management. Tenebrio molitor is cold-tolerant. Overwintering mature larvae can tolerate -2 ° C, while younger larvae die in large numbers at about 0 ° C. 2 ° C is their survival limit, 10 ° C is the starting point of development, hibernation is above 8 ° C, 25-30 ℃ is a suitable temperature range, with the fastest growth and development at 32 ℃, but it is easy to get sick if it is exposed to high temperature for a long time. It will heat die if it exceeds 32 ℃. The above temperature refers to the internal temperature of the insect body.
2. Humidity control. Tenebrio molitor is resistant to drought and can survive in feeds with a moisture content of less than 10%. In a dry environment, the growth and development are slow, the insect body is reduced, and a lot of feed is wasted. The ideal feed moisture content is 15%, and the humidity is 50 ~ 80%. For example, feed moisture content exceeds 18%, air humidity exceeds 85%, growth and development are slowed down, and disease is easy to occur, especially moths are most likely to become sick. If the breeding room is too dry, you can sprinkle clean water. If the humidity is too high, ventilate it in time. The water content of the mealworm body is 48-50%.
3. Lighting control. Tenebrio molitor is a warehouse pest. It is afraid of light by nature and is active by nature. It is active day and night, indicating that it does not require sunlight. Female adults lay more eggs in dark places than under strong light.
How yellow mealworms multiply
The suitable reproduction temperature for bread worms is 20-30 ° C. At 20-25 ° C, the egg stage is 7-8 days, the larva stage is 122 days, and the pupal stage is 8 days. It takes about 133 days from egg development to adult. At 28-30 ° C, the egg stage is 3-6 days, the larval stage is 100 days, and the pupal stage is 6 days. It takes only 110 days for the eggs to develop to adult. Humidity also has a great impact on its reproduction. The relative humidity is suitable to be 60 to 70%. When the humidity is too high to 90%, the larva grows to the 2nd to 3rd instars and most of them die. When it is less than 50%, the spawning amount is greatly reduced .
