The Key to High and Stable Yield of Tenebrio molitor L.

Temperature and humidity are the conditions for high and stable yield. The most basic conditions for breeding Tenebrio Molitor are temperature and humidity. It grows normally when the temperature is 20-35 ℃ and the humidity is 60-70%. When farmers are heating up in winter, most of them can raise the temperature to more than 20 ℃ in the daytime, while it generally decreases by 4-5 ℃ at night. Tenebrio Molitor grows slowly when it is below 15 ℃. If you can't keep more than 20 ℃ at night, you won't gain weight no matter how much feed you eat during the day, and no matter how much coal you burn. The feed, coal and output ratio is equal to zero. Therefore, it is most important to keep the room temperature above 20 ℃ during the day and night in winter.

Inappropriate humidity can easily lead to the death of Tenebrio Molitor, especially in the pupation stage. When the humidity is too high, the pupa will rot; if the humidity is too small, the pupa will not emerge. The solution of too low humidity: ⑴ sprinkled water in the breeding room; ⑵ adjusted the times of replenishing water; ⑶ increased the water content of the main feed. The solution to high humidity is: ⑴ opens the window to ventilate when the temperature is high. Install a ventilator when the ⑵ temperature is low. ⑶ places moisture absorbers such as quicklime and charcoal in the breeding room, and dehumidifiers can be used if the conditions are good. Second, feed is the premise of high and stable yield. Poor feed not only affects the growth of Tenebrio Molitor, but also causes death in a large area. Vegetables that have been treated with pesticides cannot be fed, and wheat bran mixed with talcum powder cannot be fed. The main feed and secondary feed should be matched reasonably. When feeding wheat bran, you should feed green fodder along with it, and then chase and feed green fodder according to the humidity of the breeding room. When the humidity is too high, the green feed is fed once every 4-5 days, and once every other day when the humidity is too small. Feed green fodder evenly so that all worms can eat it. If there is no main feed in the feed box and only insect dung is left, do not feed green feed. Third, the number and nutrition of adults are the key to high and stable production. Adults need supplementary nutrition when laying eggs. Insufficient nutrition will shorten the life cycle and reduce the yield. Adults should have adequate feed when laying eggs, renew green feed every day, and feed multivitamins once a week. In this way, not only the hatching rate of the spawning rate is increased, but also the insects produced are fat and strong. The life span of adults is 60-90 days. The number of adults can not be reduced, and it should be replenished in time, that is, strong dynamic and large individuals are selected to supplement the adults. Generally buy 50 kilograms to maintain at least 15-20 kilograms of adult population, so that the yield will be stable. Fourth, the hatching rate is the decisive factor for high and stable production and the method to improve the hatching rate: ⑴ sets up a special hatching room, the temperature can be controlled and maintained at 25 ℃, the hatching rate can reach more than 90%; ⑵ maintains the humidity needed for hatching; adults of ⑶ egg boxes should be picked out in time to prevent adults from eating eggs.
