Spinning habit:
According to the habit of eating, sleeping and eating, people compare silkworms to a newborn baby and affectionately call them "silkworm babies". In fact, silkworm sleep is not a passive rest, but a way of self-renewal during its growth.
Silkworms have to be skinned four times in their lives, and once they are skinned, they will grow back, and every time they are in their sleep. Silkworms are restless when they sleep. It turns out that the silkworm brain can secrete a brain hormone. Brain hormones can also make the body produce juvenile hormones and exfoliating hormones.
The ability of juvenile hormone is to maintain the appearance of larvae after peeling, inhibit the appearance of adult characteristics, and keep silkworms young; The function of desquamation hormone is to accelerate the maturity of larvae.
The two are opposite and complementary, and the unity of opposites promotes the growth of silkworm. By the middle age of five, the secretion of juvenile hormone in the body basically stopped, the function of molting hormone was strengthened, and the silkworm matured quickly.
