Silkworm baby information Silkworm baby introduction

1, silkworm baby, also known as silkworm, feeds on mulberry leaves and spins cocoons. It is one of the economic insects. Silkworm originated in China. As early as four or five thousand years ago, our ancestors planted mulberry and sericulture, which is recognized as one of the great discoveries in the world.

2. Silkworm babies are domesticated from primitive silkworms that lived on mulberry trees in ancient times. They are homologous to wild silkworms that eat mulberry trees in China today, and have 28 pairs of chromosomes. The development temperature of silkworm is 7-40℃, and the optimum feeding temperature is 20-30℃, which is mainly distributed in temperate, subtropical and tropical regions.

3. Silkworm is a completely abnormal insect, which has to go through four stages of development with completely different morphology and physiological functions: egg, larva, pupa and adult. Eggs are the stage of embryogenesis and development to form larvae, larvae are the growth stage of feeding, pupae are the metamorphosis stage of the transition from larvae to adults, and adults are the reproductive stage of mating and spawning to reproduce offspring. The whole generation only eats in the larval stage, storing nutrients for the life activities of pupae and adults.
