There are four tricks for the development of silkworms

The key to controlling daily sleep is to ensure temperature. The first-fruit mulberry temperature was 28°C, the sleep temperature was 26.5°C; the second-inocline mulberry temperature was 27.5°C, the sleep temperature was 25°C; the third-incubation mulberry temperature was 25°C, and the sleep temperature was 24°C. From the day of receiving the ants (the first day), the ants were collected at 8 am, about the 16th day of the fourth day (for mulberry), and on the seventh day, they ate at 21:30. Temperature is crucial to control "sleeping on a daily basis", especially the temperature within 24 hours of receiving ants has a great influence on the speed of development, physical fitness and uniformity of silkworms. To create a high-temperature, high-humidity microclimate, daily sleeping requirements can generally be achieved.

Early observation of mulberry has observed that about 4/5 of the silkworms have slept when they fall asleep, allowing them to eat the left leaves of silkworms. This is a good time for calming silkworms. According to observations, the front half of the silkworm is raised and does not move. There is a triangular new head at the top of the head. It gradually becomes apparent from small to large. If the triangle head area obviously appears, it is too late. Especially in the fourth sleep, the half-bodied body was lifted into a suitable period for silkworm and mulberry, and it was easy to observe.

Timely mention of youth When more than 90% of silkworms have fallen asleep, a small number of unsayed green headed silkworms are raised for breeding. This is a remedy for the neatness of the group. First spread a layer of eschar or lime powder covering the residual mulberry on the silkworm seat, and then cover a silk net on the silkworm body, and sprinkle the appropriate mulberry leaf on the net until the green head silkworm climbs on the mulberry leaf, and then take out another breeding. For ease of management, appropriate amounts of greenhead silkworms can be cultured.

According to the investigation, the sericulture people often fear the hunger and larvae, and often appear to the mulberry early phenomenon, which will lead to the development of silkworms. From the individual's point of view, silkworm pupa can feed for 2 hours after the skin, but silkworms have stronger hunger-resistance and can appropriately postpone foraging. Generally, it is better to feed for about 10 hours after 1/2 silkworm.
