Breeding Superworms: A guide to raising and breeding superworms

Add about 1 inch of wheat bran or a pre-made gutload to the bottom of the container. The beetles will eat and lay their eggs in this. Try not to use coarse bedding such as oats unless you blend it to a powder. This will make it easier to separate the superworms later for cleaning or feeding your animals.

This was achieved by characterising the F2 population of a cross between an early-and-rapidly hardening clone and a late-and-slowly hardening clone. The cold hardiness of stems was estimated using the infrared reflectance spectra of dried and homogenised samples. This method was first calibrated against the freeze test method.

Cells can endure storage at low temperatures such as--196 degrees C for centuries.

They do so if cooling is too rapid, because with rapid cooling insufficient cell water is removed osmotically to ...
