After the mature silkworm has spun silk, its body shrinks slightly into a spindle shape and remains still. At this point, it is called a dormant pupae (pre pupae). The latent pupa is the period when the dermis layer separates from the larval epidermis and forms the pupal epidermis, which takes about 2 days. The process of metamorphosis and molting is the result of the action of molting hormones. The newly molted pupae are spindle shaped, milky white, and later turn dark brown. The pupae are divided into three parts: head, chest, and abdomen. The female pupae have a large abdomen with a blunt and rounded end, and there is a longitudinal line on the midline of the eighth abdominal segment; The male pupae have a small and pointed abdomen, with a brown dot in the center of the 9th abdominal segment. The general weight of pupae is 1.5-2.5 grams. During the pupal stage, there is intense destruction of larval tissues and organs, as well as physiological processes such as the occurrence and formation of adult tissues and organs, and the development and maturation of reproductive cells. After pupation, adult development is completed about 14 days later. At this time, the eclosion hormone synthesized and stored in the pharyngeal side of the body by the brain nerve secretion cells is secreted into the bloodstream due to light stimulation. After about 40 minutes, the pupae will emerge.
