Production method of super-selenium-enriched tenebrio molitor

Abstract

The invention relates to a production method of super-selenium-rich tenebrio molitor, and straw, leftovers of agricultural production and selenium-containing raw materials are directly subjected to fungal conversion so as to become a nutritional feed loved by tenebrio molitor. According to the method, the cost of the breeding feed is reduced to be less than one third of that of an original feed, the purpose of selenium enrichment is achieved, the breeding economic benefit is increased by more than three times, and the problem that the crop straw is efficiently utilized is solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a production method of super selenium-enriched Tenebrio molitor. Background technique [0002] Tenebrio molitor is a holometabolous insect, and its life (referring to a growth cycle) can be divided into four stages: egg, larva, pupa, and adult. [0003] Eggs: oval, milky white, with markings on the surface. The egg length is (1.72±0.27) mm, and the egg width is (0.91±0.09) mm. The hatching rate of eggs laid by indoor rearing in August was 88.24%. [0004] Larva: The body is slender and cylindrical, the body length of mature larvae is (24-29) mm, the newly hatched larvae are milky white, and then turn yellowish brown, the front and back edges of each node are light brown, the internodes and ventral surface are yellowish white , the body length and head shell width of each instar larvae are relatively stable, which is the main basis for larval age class...
