How do Tenebrio Molitor reproduce?

Tenebrio Molitor is what we often call bread worms, it is a soft reptile, it has its figure in many parts of our country at present. Tenebrio Molitor has a high breeding value, and now there are a lot of people raising it. However, many people do not know much about its specific breeding methods and breeding techniques before breeding.

How to raise yellow powder insects

1. Temperature management. Tenebrio Molitor is cold-tolerant, overwintering mature larvae can tolerate-2 ℃, while low instar larvae die in large numbers at about 0 ℃, 2 ℃ is its survival limit, 10 ℃ is the starting point of development, hibernating above 8 ℃, 25-30 ℃ is the suitable temperature range, the fastest growth and development is 32 ℃, but it is easy to get disease when exposed to high temperature for a long time, and it will die when it exceeds 32 ℃.

2. Humidity control. Tenebrio Molitor is drought-resistant and can survive in feed with a water content of less than 10%. In a dry environment, it grows slowly, reduces the worm body, and wastes a lot of feed. The ideal feed water content is 15% and the humidity is 50% 80%. If the feed water content exceeds 18%, the air humidity exceeds 85%, the growth and development slows down, and it is easy to get sick, especially the moth is most likely to get sick. If the culture room is too dry, clear water can be sprinkled, and the humidity should be ventilated in time. The water content of Tenebrio Molitor is 48-50%.

3. Lighting control. Tenebrio Molitor was originally a warehouse pest, afraid of light, active, and active day and night, indicating that there is no need for sunlight, and female adults lay more eggs in dark places than in strong light.

How does Tenebrio Molitor reproduce

The suitable reproduction temperature of breadworm is 20: 30 ℃. At 20: 25 ℃, the egg stage is 7-8 days, the larva stage is 122 days, and the pupa stage is 8 days. At 28 ~ 30 ℃, the egg stage, larval stage and pupa stage are 3-6 days, 100 days and 6 days respectively, and it takes only 110 days for eggs to develop to adults. Humidity also has a great impact on its reproduction, the relative humidity is 60% to 70%, when the humidity is too high to 90%, most of the larvae die when they grow to the 2nd and 3rd instar, and when the relative humidity is less than 50%, the number of eggs laid is greatly reduced.

What's good for the yellow powder worm?

1. The commonly used formula for larvae: wheat bran 70%, corn meal 25%, soybean powder 4.5%, feed multivitamin 0.5%. Mix the above ingredients well, press them into particles through a feed granulator, or dress up into balls with 16% boiled water and press them into small cakes. Use after drying.

2. The commonly used formula for adults: fish meal 4%, corn meal 15%, wheat bran 75%, sugar 4%, feed multivitamin 0.8%, mixed salt 1.2%, the processing method is the same as the larva formula, this formula can increase the fecundity of Tenebrio Molitor and prolong the life span of adults.

Disease control of yellow powder insect

1. Tenebrio Molitor dry blight. Prevention and treatment: in the hot summer, the feeding box should be placed in a cool and ventilated place, or open doors and windows for ventilation, timely supplement various vitamins and green fodder, and sprinkle water on the ground to cool down to prevent the occurrence of the disease. When heating with a coal stove in winter, the air humidity in the feeding room should often be measured with a temperature and hygrometer. Once it is less than 55%, it is necessary to sprinkle water to the ground to humidify, or increase the moisture in the feed, or give more green fodder to prevent the occurrence of the disease.

2. Yellow powder insect rot. Prevention and treatment: after discovering this situation, we should immediately reduce or stop feeding green vegetable feed, clean up the feces of diseases and insects in time, open doors and windows to vent moisture, and pick out diseases and insects that become soft and black in time. If the humidity in the continuous overcast and rainy room is high and the temperature is low, the coal-fired stove can be heated up and drained to provide a suitable temperature.

The most important thing for Tenebrio Molitor in breeding is to control the temperature, humidity and light. Too high or too low temperature is disadvantageous to its growth. Tenebrio Molitor usually needs to strengthen the management of feeding and diseases. Only by doing a good job can the Tenebrio Molitor grow better.
