Nanchong, Sichuan: Raise stiff silkworms in winter and make money without silk or cocoons

Silkworms are generally raised in spring and autumn. It is rare to hear of people raising silkworms in winter. What’s even more incredible is that these off-season farmers deliberately make silkworms sick. Why is this?

In this silkworm house in Huilong Town, Gaoping District, Nanchong, Sichuan, white Bombyx silkworms are raised. Beauveria bassiana does not spin silk and make cocoons, but the dried worm bodies of silkworm larvae that are killed by Beauveria bassiana. In traditional sericulture, Beauveria bassiana is the nemesis of silkworms. To cultivate Beauveria bassiana, the silkworms must be artificially infected with Beauveria bassiana.

Pu Xiugang, the person in charge of a sericulture breeding cooperative in Nanchong, Sichuan: This is the bacteria application process for cultivating White Bombyx silkworms. At this time, we calculate back how many days the silkworms will grow, and then prepare the concentration of bacteria based on the number of days. By then it will have ossified on its own.

The dead silkworms can be used as medicine and in the production of beauty products after being dried and processed. Currently, the market price of zombie silkworms is around 200 yuan per kilogram. This four-season cycle of raising zombie silkworms allows farmers to raise more than 20 batches a year. Using intelligent silkworm room equipment, compared with the traditional breeding model, the labor force can be reduced by half, and the per capita annual income of silkworm farmers can be increased by three times.
