Detailed Explanation of Rearing Standards and Key Technical Points for Young Silkworms
The key to rearing young silkworms is to master reasonable temperature and humidity, appropriately mature fresh mulberry leaves and reasonable techniques for handling molting and awakening. For leaves used for collecting newly hatched silkworms, the leaf color is yellow with a hint of green, slightly wrinkled; in spring pick the 2nd leaf, in summer and autumn pick the 2nd-3rd leaf. For the 1st instar, use moderately mature leaves that are green with a hint of yellow, with a flat leaf surface, the 3rd-4th leaf, preferably tender rather than old, depending on the climate. For the 2nd instar, moderately mature leaves have a normal green color; for the 3rd instar in spring, three-eye leaves can be used. For the 1st-2nd instars, cut leaves into square pieces 1.5 times the body length of the silkworm, and use strip leaves when expanding the rearing bed. During the spring silkworm season, one can aim for 10 days to the third molt.
