What if cocoons don’t produce moths?

Best answer: Keep the temperature in the container of silkworm cocoon at about 20℃, which is the fastest temperature for silkworm pupa development. Keeping at this temperature can shorten the time for moth emergence. It takes time for silkworm to complete metamorphosis in pupa. There is no way to shorten the development period except to speed up the development. Early moth emergence will only lead to the failure of moth development and the moth produced will die.
