Tenebrio breeding has become a trend because of its high protein content of more than 50%, the reason why the nutritional value of adults is high, become the first choice for animal farmers feed, used for raising fish, shrimp, razor clams, cockroaches, cockroaches and so on. And Tenebrio oil is also an excellent edible oil, health food supplement oil, cosmetic additives and transformer oil. The larvae mealworms can also be eaten as food. After baking or frying, the taste is fragrant and delicious. There are sales points in major cities such as Guangdong, Shanghai, and Beijing.
Tenebrio molitor is a kind of warehouse pest, widely distributed throughout the world, and it can also be raised in urban and rural residential houses, balconies, corners or simply constructed greenhouses, so it is now welcomed by a large number of farmers.
2. Cultivation method of yellow mealworm(1) Feeding site preparation
Tenebrio breeding sites should be selected light dark, good ventilation and ventilation, good insulation effect in order to avoid the winter temperature is too low, resulting in the large-scale death of Tenebrio, Tenebrio activity at room temperature 13 °C feeding, 5 °C can still grow, Above 35 °C will cause a large number of deaths, so winter must be equipped with thermal facilities, equipped with ventilation fans in the summer to ensure that the temperature is appropriate.
(2) Feeding frames
In order to improve the utilization rate of Tenebrio breeding grounds, we now advocate three-dimensional breeding and multi-layered breeding frames. The materials are steel frames divided into six layers, each of which can hold about six feeding trays, which is not only reliable but also easy to raise. .
(3) Breeding box
The breeding cages are preferably made of tin cages with a size of 60 cm × 45 cm × 15 cm. They can also be raised with basins, porcelain basins, and tile tanks. The breeding equipment requires that the inner wall is smooth, and screens are used as covers to prevent crawling of young and adult insects, spiders, geckos, and crickets.
(4) Feed preparation
Tenebrio is divided into four growth stages: eggs, larvae, cockroaches, and adults. After the cocoon has passed through the difficult eclosion, the waste materials and moltings in the crates must be removed in a timely manner and green materials should be added (mainly including natural pasture, cultivated pasture, and green crops). , leafy vegetables, non-starchy root melons, aquatic plants, etc.) When feeding adults, add some fresh concentrate. Adults grow again for about 6 to 11 days and begin to spawn. At this time, farmers should pay attention to placing white paper at the bottom of the spawning box to concentrate the eggs of Tenebrio molitor and feeding a small amount of concentrate feed. In order to save costs, it is recommended to use gold. Fermentation of baby feed fermentation stalks, appropriate amount of auxiliary corn flour, bran or rice bran fermentation together, the effect will be better. The fermented feed not only has comprehensive nutrition and good palatability, but also enhances the appetite of the mealworms, promotes digestion and absorption, thereby increasing feed intake, growing fast, and reducing illness, greatly improving the economic benefits of the mealworm culture.
When the larvae have increased their skin food intake, they should add more concentrate; the amount of feed for one day should be limited to the amount of feed consumed in the box at night, and the amount of feed should be added in the morning and evening and the method of supplementing at noon; As a supplement, the latter is dominated by green materials, supplemented by fine materials. The larvae will phlegm after 14 to 15 times of pupa. At this time, they should cast more green material to facilitate the rapid emergence of adult worms.
3. Fine feed fermentation process(1) Preparation. First, we must remove the mildewed straw and crush it. Then use the ratio of 500 kg of fermented stalks of 1 kilogram of gold bait feed starter, and pour the starter into 30~35 degree warm water (cold water can be used in summer) to fully mix, and then dilute the good fermentation bacterium and the crushed straw. well mixed. And control the moisture content between 60 ~ 65%, judging methods: grasping a handful of material, fingers see the water does not drip, landing is scattered suitable, more water is not easy to warm, less water difficult to ferment, add about 10% Corn flour, bran or rice bran are fermented together and the effect will be better.
(2) Do heaps. The straw powder mixed with the golden bait straw fermentation starter is piled into a material stack with a height of 40 to 50 cm and a length and width, and a thermometer is placed on the stack, and a breathable moisture-retaining moisturizing cover is covered for fermentation.
(3) temperature control. Summer generally ferments 6~8 hours. For winter temperatures above 15°C, it takes 16-24 hours to ferment. If it is lower than 15°C, warming measures should be taken to maintain the fermentation temperature above 15°C.
(4) Turn over. Fermentation temperature can not exceed 45 degrees to prevent excessive fermentation deterioration, affecting the nutritional properties of straw fermentation feed. When the temperature reaches 40 degrees, it needs to be turned over once, and the entire fermentation process is suitable for overturning one or two times.
(5) Completed. When the straw powder gradually turns yellow and accompanied by the aroma of wine, it indicates that the fermentation is basically completed. At this time, the cover should be removed, the bulk of the cake should be cooled down, dried and dried, and should not be dried.
(6) Fermentation again. When the moisture content drops below 25%, add the Goldbeet type 2 feed starter, the proportion is about 0.1~0.2%, and stir and mix. Sealed fermentation should be conducted at this time, and fermentation can be completed in about 1 day.
Tenebrio breeding technology is simple, but attention should be paid to changes in the temperature during the breeding process of the mealworms, and timely adjustments are made to ensure that the growth temperature of the mealworms is comfortable. In addition, as the growth period of Tenebrio is different, the feeding of feed should also pay more attention to changes, otherwise it will affect the breeding effect of Tenebrio.
