First, temperature and humidity are the conditions for high yield and stable production. The most basic condition for breeding yellow mealworm is temperature and humidity. Temperature is normal at 20-35°C and humidity 60-70%. When farmers raise their temperature during the winter, most of them can raise their temperature to more than 20°C during the day and generally decrease 4-5°C at night. Tenebrio slow growth at less than 15 °C. If you can't keep above 20°C at night, no matter how much feed you eat during the day, it won't gain weight. No matter how much coal is burned, it's white. The feed, coal, and output ratios delivered are equal to zero. Therefore, keeping the room temperature above 20°C during the winter and nighttime is the most critical. Inappropriate humidity can easily cause the death of Tenebrio, especially during the pupation stage. When the humidity is too high, it will rot; if it is too small, it will not be achieved. The solution of the humidity is too small: (1) sprinkle water in the breeding room; (2) adjust the times of water supply; (3) increase the moisture content of the main feed. The solution to high humidity is: (1) Open the window for ventilation when the temperature is high. (2) When the temperature is low, install a ventilation fan. (3) Place moisture-absorbing materials such as quick lime and charcoal in the culture room, and use a dehumidifier with good conditions. Second, the feed is a prerequisite for high and stable production feed bad not only affects the growth of Tenebrio, but also cause a large area of ​​death. Any leaf that has hit pesticides cannot be fed, wheat bran with talcum powder cannot be fed. The main feed and the deputy feed should be used properly. When feeding wheat bran, it should follow the feeding of green feed, and then follow the size of the humidity in the breeding room and follow the green feed. When the humidity is too high, the green feed is fed once for 4-5 days, and once every other day when the humidity is too low. Feed the green feed evenly so that all insects can eat it. If there is no main feed remaining in the feed box, do not feed green feed. Third, adult population and nutrients are the key adults for high yield and stable production. It is necessary to supplement nutrients when spawning, and insufficient nutrition will shorten the life cycle and reduce the yield. Adults should have sufficient feed when they lay eggs, fresh green feed should be renewed every day, and multivitamins should be fed once a week. This not only increases the hatching rate of the egg production rate, but also produces the insects that are both fat and strong. The adult life is 60-90 days. The number of adults can not be reduced, it is necessary to add in time, that is, to select adult animals that have strong activity and individuals in the commercial insects. The general purchase of 50 kg at least to maintain the number of 15-20 kg of adults, so that production will be stable. 4. The hatching rate is the determinant of high production and stable production to increase the hatching rate: (1) Set up a special incubation room, the temperature can be controlled and maintained at 25°C, the hatching rate can reach more than 90%; (2) Keep the humidity required for incubation; (3) Adult egg trays should be singled out in time to avoid adult eggs.
