The laws of silkworm silkworms

Silkworms go through four stages of egg, larva, cockroach and adult life. The larval stage of silkworm is the stage that people call silkworm baby. Generally speaking, sericulture refers to the feeding of larvae. Larvae go through 4 times of molting from hatching to pod formation. People thus divide the larvae's passage into five ages. During the period before the molting, silkworms do not eat or move and are called sleeping. From one to four years old, silkworms need to sleep four times, and the fifth instar silkworm no longer sleeps at the later stage, but instead lay silkworms and clams, and phlegm in the cocoon, thereby completing the larval stage of silkworms. The newly hatched silkworm is called ant silkworm. The just-skinned silkworm is called silkworm, and the silkworm that sleeps is called sleep silkworm. The silkworm that is about to sleep will call it sleep silkworm, and the silkworm that will lay on the silkworm later in the fifth instar will be called mature silkworm. According to the physiological characteristics of silkworms, one to three instars are generally called small silkworms, and four to five instars are called silkworms. The length of the larval period differs depending on the variety and temperature. The general silkworm period is about 25-28 days, and the summer and autumn silkworm period is about 20-22 days. From the time when the mature silkworms are picked up to the picking process, they are called crickets. In general, it is divided into three phases: the site from whereupon to the campsite is fixed (formation of the plutonium network) is the initial stage (preceding stage), the pupation site is fixed to the end of silking is the stage of silking (middle stage), and the spinning is completed. When the temperature is 24°C (75°C), it is generally 1 day after the initial period. During the pupation stage, from the end of silking to the pupalization, after two days and nights, the carcasses of the first pupal were pale milky yellow, and the body skin was weak and easily broken. After two days and nights, the carcasses gradually changed from pale yellow to yellow brown. At this time, it is suitable for picking. The passage of time in the cockroaches is related to the temperature, but also related to silkworm varieties. The long-term use of plants in spring will take a long time and the species will be shorter in summer and autumn. The general spring period is about 7 days, the summer period is about 5 days, the Mid-Autumn Festival is about 6 days, and the late autumn is about 7-8 days. The main reason for picking pods is to look at the husk color. The spring period is better when the tan is yellow, and the summer and autumn seasons are better, that is, tender can also be picked.
