Tenebrio molitor, also known as bread worm, belongs to COLEOPTERA, Tenebrionidae and Tenebrionidae (Tenebrionidae) in insect taxonomy. Originally from northern China, it was introduced by the Soviet Union in the 1950' s. Dried Tenebrio molitor contains 30% fat and 50% protein. In addition, it also contains major elements such as phosphorus, potassium, iron, sodium, aluminum and various trace elements. Because the dried Tenebrio molitor larvae contain about 40% protein, 57% pupae and 60% adults, it is known as "the feed treasure house of protein".
Flat and oblong, with a body length of (13.020.91) mm+0) mm, and a body length of (4. 1 1.33) mm, the newly emerged adult's coleoptera is beige and the chest backboard is brown. After 3 hours, the coleoptera turns reddish brown, and after 3 to 4 days, the adult coleoptera turns reddish brown.
The eggs of adults are scattered about 3 ~ 5 days before spawning, which can be produced in feed or on paper at the bottom of feed. Adults lay eggs on the top layer of loose wheat bran feed with 20 mesh sieve, and 97.4% eggs are laid on paper. Under the same thickness (5cm), only 265,438+0.4% of the eggs are laid on paper with flour instead of wheat bran. Adults generally do not lay eggs or rarely lay eggs without feed.
